| Linkandzelda | DocScrutinizer05: Last Measured Discharge: 1252 mAh | 01:18 |
|---|---|---|
| kerio | that's pretty decent | 01:27 |
| kerio | what was the draw? | 01:27 |
| DocScrutinizer51 | Linkandzelda: sounds correct | 01:33 |
| DocScrutinizer51 | now after next unplug from charger start the calibrate script right away | 01:34 |
| Linkandzelda | DocScrutinizer51: i'll let it charge up again until tomorrow morning, and will run it again | 01:35 |
| Linkandzelda | though it died from 100% in 9 hours in standby with only SSH running and xchat for 5 mins | 01:35 |
| DocScrutinizer51 | yes, let it charge up tonight, and tomorrow after unplug start the script | 01:35 |
| DocScrutinizer51 | ideally run bq27200.sh 60 >>xxxxm in parallel | 01:37 |
| DocScrutinizer51 | Linkandzelda: actually I ponder to make bw27200.sh >>/var/log/batlog.txt an autostart on my device | 01:41 |

| ceene | also, i don't feel that much comfortable with donatios | 13:33 |

| Wizzup | cool -- 128GB card seems to be detected by the n900 | 16:28 |
| KotCzarny | samsung pro ? | 16:28 |
| KotCzarny | anything else just sucks on 4k random writes | 16:29 |
| Maxdamantus | Pretty much any SD card will be. | 16:29 |
| Wizzup | Uh, I don't buy SD cards for speed | 16:30 |
| Wizzup | They're all the category of: SLOW | 16:30 |
| KotCzarny | nope | 16:30 |
| KotCzarny | samsung pro excel at 4k writes | 16:30 |
| KotCzarny | which means 10-100x faster than anything else | 16:30 |
| Wizzup | And does the n900 interface support that? | 16:30 |
| Wizzup | And what job would you do on your n900 to require that | 16:30 |
| KotCzarny | as someone pointed out 5 minutes on apt-get upgrade instead of 2 hours | 16:30 |
| KotCzarny | chroot running? | 16:31 |
| Wizzup | Are you suggesting I run my rootfs on a sd card? | 16:31 |
| KotCzarny | compiling/running chroots/vms | 16:31 |
| Wizzup | I would never compile on a SD card. | 16:31 |
| Wizzup | Although it is true, I run gentoo on a sd card on my other n900, but I never use my n900 to build anything | 16:31 |
| KotCzarny | building all packages for that gentoo externally? | 16:32 |
| Wizzup | On my laptop. Chrooted into the n900 sd card. | 16:32 |
| Wizzup | but all the I/O is done on a tmpfs. | 16:32 |
| Wizzup | Except for the 'make install' phase :) | 16:32 |
| KotCzarny | anyway, it's 4MB/s vs 40kB/s on random writes | 16:32 |
| Wizzup | I mostly care about reads | 16:33 |
| KotCzarny | similar story | 16:33 |
| KotCzarny | http://forum.armbian.com/index.php/topic/954-sd-card-performance/ | 16:33 |
| Wizzup | I'll benchmark it for you if you want, even though I don't care and I'm quite happy with my sd card :) | 16:33 |
| Wizzup | They're all in the "not useful for anything but slow access" category | 16:33 |
| Wizzup | people using armbian have very different use cases I think | 16:34 |
| KotCzarny | yes, running as rootfs | 16:34 |
| KotCzarny | i was planning to run n900 from sd card too | 16:34 |
| Wizzup | I mean, for work we have our own embedded distro running on allwinner machines | 16:34 |
| Wizzup | It's a custom gentoo one, and all the device needs for updates is a 4MB squashfs system | 16:35 |
| Wizzup | (It will run portage and everything else, but it will fetch binary packages) | 16:35 |
| Wizzup | So I'm not really worried about the i/o regardless | 16:35 |
| Wizzup | but this was just for: cool, I can store so much on my n900, it's insane, idea | 16:35 |
| KotCzarny | :) | 16:35 |
| * Maxdamantus has been using a 128 GB card for a while. | 16:36 | |
| KotCzarny | now imagine n800 has 2 full size sd slots ;) | 16:36 |
| *** sq-one has quit IRC | 16:36 | |
| ceene | http://www.amazon.com/Samsung-Class-Adapter-MB-MG64DA-AM/dp/B00IVPU88U | 16:36 |
| ceene | one of these, KotCzarny? | 16:36 |
| KotCzarny | looks like | 16:36 |
| Wizzup | KotCzarny: there was also a samsung 128gb card in the shop, about 20 eur more | 16:36 |
| KotCzarny | my next sd card will be samsung pro | 16:36 |
| Wizzup | This is a transcend one | 16:37 |
| KotCzarny | remember samsung makes the flash chips so they can put higher quality chip at lower price | 16:37 |
| freemangordon | Wizzup: I have 128GB sammy pro and can confirm that it makes all the difference when you put swap on it | 16:38 |
| * Maxdamantus expects SD cards to die eventually. | 16:38 | |
| Wizzup | I see, maybe I'll go to plesio and get one at some point. | 16:38 |
| Wizzup | Maxdamantus: Me too | 16:38 |
| freemangordon | I have that one for,umm...., 2? 3? years? | 16:38 |
| KotCzarny | create 32 swapfiles and rotate them every month? | 16:38 |
| freemangordon | this make no sence | 16:39 |
| KotCzarny | ok, 8 | 16:39 |
| freemangordon | the controller in the card is supposed to do the wear leveling | 16:39 |
| KotCzarny | fmg, when you write a file its marked as used? | 16:39 |
| *** ArGGu^^ has joined #maemo | 16:40 | |
| Maxdamantus | "write a file" isn't something the SD card understands. | 16:40 |
| freemangordon | I am not sure I understand the question | 16:41 |
| Maxdamantus | also, 2 years? Didn't know they had 128 GB microSD cards that long ago. | 16:42 |
| freemangordon | or even 3 years, I really can't remember | 16:43 |
| Maxdamantus | apparently SanDisk introduced the first one in Feb 2014. | 16:44 |
| KotCzarny | idea is sd card doesnt use new block every time, only when it detects that block needs wear levelling | 16:44 |
| KotCzarny | i might be wrong because i dont know the real algo used | 16:44 |
| KotCzarny | maxd: samsung pros are ~3-4 years old | 16:44 |
| freemangordon | KotCzarny: I wouldn't dare to predict what might have been implemented in the card controller :) | 16:44 |
| Maxdamantus | KotCzarny: but not 128 GB ones. | 16:44 |

| freemangordon | yep, mine is class 10 | 16:47 |
| KotCzarny | funny as it is google sucks at finding release news for pros | 16:47 |
| * Maxdamantus is using a "SanDisk 128GB Ultra® microSDXC™ UHS-I Class 10" | 16:48 | |
| freemangordon | Maxdamantus: this card is like snail | 16:49 |
| Maxdamantus | was using some 64 GB Kingston thing not too long ago, but it did actually seem to have bad performance. | 16:49 |
| KotCzarny | there are only few flash chips manufacturers | 16:49 |
| KotCzarny | and there are plenty of fakes, kingstones are leading in that area | 16:49 |
| Maxdamantus | I don't think it'd be a fake. I just bought pretty much the cheapest one. | 16:50 |

| KotCzarny | maxd: check manf id in /sys | 16:50 |
| Maxdamantus | Don't the "fake" ones usually have limited storage? | 16:51 |
| Maxdamantus | (but where they pretend to still maintain everything) | 16:51 |
| KotCzarny | maxd: doesnt matter, thing is they are usually done via ghost runs in real factories but using degraded material | 16:52 |
| KotCzarny | also, serial number is usually low | 16:52 |

| Linkandzelda_ | DocScrutinizer05: ive had that tab open for a few days, i'll get to it soon, hehe | 18:54 |
| DocScrutinizer05 | anyway screen-on *massively* depends on brightness setting and usually even ambient light | 18:55 |
| *** Mek has joined #maemo | 18:56 | |

| *** at1as has quit IRC | 18:59 | |
| DocScrutinizer05 | Linkandzelda_: for example WLAN eats huge amounts of power when enabled but *not* logged in to a WLAN-AP | 19:05 |
| Linkandzelda_ | DocScrutinizer05: how do i get current mA value? | 19:07 |
| DocScrutinizer05 | by reading 2nd col ;-) | 19:07 |
| Linkandzelda_ | ok | 19:08 |
| DocScrutinizer05 | it's a almost singular measurement, averaging over at max 2.5s | 19:09 |
| Linkandzelda_ | Average Current: 158 mA | 19:09 |
| Linkandzelda_ | right now: screen off, wifi on (connected), ssh on and connected (2 connections), bq script logging + calibrate running. no sim, no other apps running | 19:10 |
| Linkandzelda_ | seems like a lot of current | 19:10 |
| *** corvinux has joined #maemo | 19:10 | |
| DocScrutinizer05 | wifi on power savings mode MAX? | 19:10 |
| DocScrutinizer05 | AP decent? | 19:10 |
| Linkandzelda_ | AP is strong, its 2 feet from the box | 19:11 |
| Linkandzelda_ | not sure about power saving mode | 19:11 |
| DocScrutinizer05 | 2 feet might be too close actually, and PSM is not related to distance resp signal strength | 19:11 |
| Linkandzelda_ | with screen on max brightness same other situation: Average Current: 564 mA | 19:12 |
| DocScrutinizer05 | there won't be much of an option other than run the script from local xterm or using `screen` to run it, then disable WLAN | 19:12 |
| Linkandzelda_ | 42% TTE: 77 minutes | 19:13 |
| DocScrutinizer05 | WLAN without proper PSM might easily eat 200mA according to http://wiki.maemo.org/N900_Hardware_Power_Consumption | 19:13 |
| Linkandzelda_ | something isnt going right thats for sure lol | 19:13 |
| Linkandzelda_ | going to switch to another AP | 19:14 |
| Linkandzelda_ | or not, it will kill the scripts | 19:14 |
| DocScrutinizer05 | :nod: | 19:14 |
| DocScrutinizer05 | unless you used nohup or screen | 19:14 |
| KotCzarny | Linkandzelda_: did you check with wlan off? | 19:15 |
| DocScrutinizer05 | there won't be much of an option other than run the script from local xterm or using `screen` to run it, then disable WLAN | 19:15 |
| DocScrutinizer05 | s/using `screen`/using nohup or screen/ | 19:16 |
| infobot | DocScrutinizer05 meant: there won't be much of an option other than run the script from local xterm or using nohup or screen to run it, then disable WLAN | 19:16 |
| Linkandzelda_ | ok, except | 19:16 |

| DocScrutinizer05 | you fist need to create settings (and save them) before you can restore them | 19:34 |
| DocScrutinizer05 | first* | 19:34 |
| DocScrutinizer05 | you're free to name them any way you like, "basic" and "all" are arbitrary names I chosen | 19:35 |
| Linkandzelda_ | ok, so i enable the ones i want in ham, then save a profile, then enable others, then save another profile, etc | 19:36 |
| Linkandzelda_ | yay for screen | 19:37 |
| DocScrutinizer05 | yes | 19:38 |
| DocScrutinizer05 | exactly | 19:38 |
| Linkandzelda_ | my battery will be dead in 67 mins | 19:38 |
| Linkandzelda_ | and the calibrate script will end | 19:39 |
| DocScrutinizer05 | isn't your device a little warm already? | 19:39 |
| Linkandzelda_ | yea | 19:39 |
| DocScrutinizer05 | must get warm at this power level | 19:39 |
| Linkandzelda_ | could it be the overclock to 805? | 19:40 |
| DocScrutinizer05 | you started handwarmer app ;-P | 19:40 |
| Linkandzelda_ | i imagine it draws more power | 19:40 |
| DocScrutinizer05 | yes | 19:40 |
| DocScrutinizer05 | do not overclock! | 19:40 |
| *** l_bratch has joined #maemo | 19:41 | |
| DocScrutinizer05 | unless you know **exactly** what you're doing, and why (and that should be a really good rationale, like "otherwise the video playback skips frames2) | 19:41 |
| DocScrutinizer05 | overclocking (app) makes it damn easy to set completely nonsensical parameters, like lock CPU to 800MHz | 19:42 |
| Linkandzelda_ | if im not gonna overclock then i guess i have no reason to run kernel-power | 19:43 |
| DocScrutinizer05 | seen that a bazillion times that users came here whining about their short battery standby time - turned out they did lock CPU to always clocked at insane speed, while it SHOULD auto-adjust clock frequency and go to zeroclock 99%+ of the time | 19:44 |
| KotCzarny | hmm, where is fakeroot package? | 19:45 |
| Linkandzelda_ | oh, i made sure not to lock it, just raised the max to 805, min still at 250 | 19:45 |
| Linkandzelda_ | oh nice, extras devel has tmux as well as screen | 19:46 |
| Linkandzelda_ | will these ever make it to the stable repos? | 19:46 |
| KotCzarny | answer is: maybe | 19:46 |
| DocScrutinizer05 | prolly not | 19:46 |
| * Linkandzelda_ is tempted to upgrade everything from extras-devel and see what happens | 19:47 | |
| DocScrutinizer05 | lack of maintainers to promote them, and testers to vote them up in maemo-testing | 19:47 |
| DocScrutinizer05 | it will break your system | 19:47 |
| KotCzarny | Linkandzelda_: do it, you are on the verge of reflashing anyway | 19:47 |
| KotCzarny | and its better to risk it now than later | 19:47 |
| DocScrutinizer05 | there are a lot of broken packages in extras-devel which will replace the perfectly working versions you got now | 19:47 |
| DocScrutinizer05 | well, at least potentially | 19:48 |
| Linkandzelda_ | well | 19:48 |
| *** SpeedEvil has quit IRC | 19:48 | |
| Linkandzelda_ | i'll let this calibration script end | 19:48 |
| Linkandzelda_ | then if i decide to reflash, i will see what happens | 19:48 |
| DocScrutinizer05 | won't take long, eh? ;-P | 19:48 |
| Linkandzelda_ | 168 mins if i leave my screen off | 19:48 |

| DocScrutinizer05 | check WLAN PSM setting | 20:03 |
| Linkandzelda_ | i still dont know how to do that | 20:03 |

| Linkandzelda_ | transmission power 100 mW, power saving on (max) | 20:05 |
| DocScrutinizer05 | second row | 20:05 |
| DocScrutinizer05 | max is good | 20:05 |
| DocScrutinizer05 | your AP might not be compatible | 20:05 |
| Linkandzelda_ | any way i can find that out? | 20:05 |
| DocScrutinizer05 | TX power is basically irrelevant | 20:05 |
| KotCzarny | change channel in ap | 20:05 |
| Linkandzelda_ | i guess by disconencting and monitoring | 20:05 |
| KotCzarny | maybe its just noisy env | 20:05 |
| DocScrutinizer05 | hmm, this is very hard to find out, afaik | 20:05 |
| DocScrutinizer05 | yes, disabling WLAN and checking power during that is the easiest way to spot the culprit | 20:06 |
| Linkandzelda_ | channel is 11 | 20:06 |
| DocScrutinizer05 | irrelevant | 20:06 |
| KotCzarny | try 6 and 1 | 20:06 |
| KotCzarny | iwlist scan could help if it was supported, but you can check on laptop | 20:06 |
| Linkandzelda_ | i'll change that stuff later, since its gonna boot me out and scripts will die, not sure how to move them into a screen when they are running | 20:07 |
| DocScrutinizer05 | serach interval in first menu is relevant as long as you're _not_ connected to AP | 20:07 |
| Linkandzelda_ | that one is set to 10 mins | 20:07 |
| DocScrutinizer05 | you can't | 20:07 |
| DocScrutinizer05 | 10min ok | 20:07 |
| Linkandzelda_ | yea, didnt think so (re:screen) | 20:07 |
| DocScrutinizer05 | 30 min better, but... who would want that | 20:07 |
| *** M4rtinK has joined #maemo | 20:07 | |
| DocScrutinizer05 | you can assume each $interval time the WLAN will go active searching for APs to connect to, for at least 60s, and eats lots of power (200mA) during that time | 20:08 |
| Linkandzelda_ | well thats useless if im always on the same AP right | 20:09 |
| DocScrutinizer05 | yes, irreleavnt when you are always connected. Relevant as soon as you leave range of the AP though | 20:09 |
| DocScrutinizer05 | when WLAN is connected to an AP, it won't search for other APs, basically. It's already active all the time and only PSM allows it to go inactive | 20:10 |
| DocScrutinizer05 | 99% of time inactive, between one beacon and next, of AP | 20:11 |
| DocScrutinizer05 | you could try PSM: medium | 20:11 |
| *** Elektra is now known as ashley | 20:11 | |
| DocScrutinizer05 | sometimes yields better results with borked APs than PSM: max | 20:11 |
| Linkandzelda_ | changing it will work if im still connected without booting me? | 20:12 |
| DocScrutinizer05 | that's why PSM is a per-connection setting | 20:12 |
| DocScrutinizer05 | yes, works | 20:12 |
| Linkandzelda_ | ok | 20:12 |
| DocScrutinizer05 | it should just reconnect you instantly, which will go unnoticed by ssh | 20:13 |
| Linkandzelda_ | ok it changed | 20:13 |
| DocScrutinizer05 | my ssh sessions survive 30 minutes out-of-flat ;-) | 20:13 |
| Linkandzelda_ | gave me a power warning | 20:13 |
| DocScrutinizer05 | quite amazing to come home and see your ssh session simply resuming | 20:14 |
| KotCzarny | for survival of ssh sessions see: mosh | 20:14 |
| Linkandzelda_ | that is quite good, how is that possible | 20:14 |
| DocScrutinizer05 | ssh doesn't do much keep-alive to detect 'packet loss' | 20:15 |
| DocScrutinizer05 | so it's just like pulling your ethernet cable from your PC for a few seconds | 20:15 |
| DocScrutinizer05 | nothing really bad will happen | 20:15 |
| Linkandzelda_ | Average Current: 234 mA | 20:16 |
| DocScrutinizer05 | for the TCP stack it's just like arbitrary packet loss, worst case | 20:16 |
| Linkandzelda_ | screen on Average Current: 557 mA | 20:16 |
| DocScrutinizer05 | I'd not bet important limbs on this PSM change taking immediate effect | 20:16 |
| Linkandzelda_ | thats ok | 20:17 |
| KotCzarny | what bonehead made git depend on busybox? | 20:17 |
| DocScrutinizer05 | first go do the `nohup/screen bq27200.sh >> batlog.txt` test and disable/disconnect WLAN, tomake sure it's WLAN at all | 20:18 |
| DocScrutinizer05 | what's your AP brand/model? | 20:18 |
| Linkandzelda_ | what about calibration script? | 20:18 |
| Linkandzelda_ | it will die in 20 mins | 20:19 |
| Linkandzelda_ | the make and model, its a tp link.. something | 20:19 |
| DocScrutinizer05 | finish the calibration, then you're done with calibrating anyway | 20:19 |
| Linkandzelda_ | is it safe to reflash after calibrating? | 20:19 |
| DocScrutinizer05 | hmm, seen crappy tplink models, inded | 20:19 |
| DocScrutinizer05 | seen semi-good ones too | 20:20 |

| *** lxp has joined #maemo | 20:20 | |
| DocScrutinizer05 | sorry, can't comment. Maybe try aunt google, "$AP-model powersavings" | 20:20 |
| DocScrutinizer05 | you might want to make sure the AP doesn't send more than one beacon per second | 20:22 |
| Linkandzelda_ | beacon interval is 100 | 20:23 |
| *** Mek has joined #maemo | 20:23 | |
| DocScrutinizer05 | http://www.techworld.com/mobile/a-guide-to-wi-fi-power-save-technologies-4103/ | 20:23 |
| Linkandzelda_ | will this slow it down if thats changed? | 20:23 |
| Linkandzelda_ | also something funny, if i dont refresh the bq script its Average Current: 172 mA | 20:24 |
| DocScrutinizer05 | 100ms/beacon is still tolerable | 20:24 |
| Linkandzelda_ | then if i go and use wifi ssh it jumps to 350+ | 20:24 |
| *** chfoo0 is now known as chfoo | 20:25 | |
| Linkandzelda_ | it will die any minute so i'll disable wifi when it does and will find out the current | 20:26 |
| DocScrutinizer05 | I suspect a cablemodem WLAN router will use all sorts of bandwidth maximation techniques, neglecting any powersaving | 20:27 |
| DocScrutinizer05 | the typical usecase for such AP is to sport WLAN linked internet TV sets etc | 20:28 |
| DocScrutinizer05 | which do not need to bother about powersaving | 20:29 |
| Linkandzelda_ | makes sense | 20:30 |
| DocScrutinizer05 | I suggest you run bq27200.sh|tee -a batlog.txt from a device-local xterm | 20:31 |
| DocScrutinizer05 | I even have an icon for that ;-) | 20:32 |
| Linkandzelda_ | ok, i will kill the ssh one then | 20:32 |
| *** lobito has quit IRC | 20:33 | |

| Linkandzelda_ | i need to make a script create-screen-if-not-exists | 20:35 |
| DocScrutinizer05 | ? | 20:36 |
| Linkandzelda_ | then when i open the icon it will connect to the screen if its existing, or it will make a new one and run the logger automatically in the screen | 20:36 |
| DocScrutinizer05 | screen the command? | 20:36 |
| Linkandzelda_ | anyway, i think it just died | 20:36 |
| Linkandzelda_ | yea | 20:36 |
| Linkandzelda_ | sorry, gnu screen i usually call it | 20:36 |
| DocScrutinizer05 | I think screen has an option that does exactly that already | 20:36 |
| Linkandzelda_ | then i can have another window in that which tail -f batlog | 20:37 |
| Linkandzelda_ | i'll fiddle with that later, im going to disable wifi now | 20:37 |

| Linkandzelda_ | i just turned off wifi and the device reset itself | 20:40 |
| DocScrutinizer05 | yeah, you also might want to get man-db-n900 | 20:40 |
| DocScrutinizer05 | ;-) | 20:40 |
| Linkandzelda_ | seems current now is really low | 20:43 |
| Linkandzelda_ | 25-50 mA max | 20:43 |
| DocScrutinizer05 | plus nuke that silly docpurge, see ~jrtools | 20:43 |
| DocScrutinizer05 | that's better :-D | 20:43 |
| Linkandzelda_ | is it normal for current to be low after a reboot? | 20:43 |
| DocScrutinizer05 | err, it's always normal for current to be low ;-D | 20:43 |
| Linkandzelda_ | ok | 20:43 |
| Linkandzelda_ | oh, and, it didnt apply my OC settings | 20:44 |
| KotCzarny | Linkandzelda_: your normal current should be ~10mA | 20:44 |
| Linkandzelda_ | its 13 mA now | 20:44 |
| KotCzarny | (n900 idle, gsm on but idle, wifi off) | 20:44 |
| DocScrutinizer05 | that's normal now! | 20:44 |
| Linkandzelda_ | shall i wait a bit more or enable wifi? | 20:44 |
| DocScrutinizer05 | that's what I'd mandate | 20:44 |
| DocScrutinizer05 | well, wait a bit more, then enable wifi | 20:44 |
| Linkandzelda_ | ok | 20:45 |
| DocScrutinizer05 | you'll see current go through the roof | 20:45 |
| DocScrutinizer05 | I bet | 20:45 |
| Linkandzelda_ | i need to go away, will be back to enable it in 1-2 hours | 20:45 |
| Linkandzelda_ | will let it charge up a bit too | 20:45 |
| DocScrutinizer05 | better that | 20:45 |
| DocScrutinizer05 | btw what's your LMD now? | 20:45 |
| DocScrutinizer05 | seems your battery is in quite good condition i'd say | 20:46 |
| Linkandzelda_ | current raised to 135 | 20:47 |
| Linkandzelda_ | and its 1193 LMD now | 20:47 |
| Linkandzelda_ | 113 on max brightness, normal? | 20:49 |
| KotCzarny | it will get higher | 20:49 |
| KotCzarny | but yeah | 20:49 |
| DocScrutinizer05 | depends on ambient light, might even be higher | 20:50 |
| DocScrutinizer05 | ~power | 20:51 |

| Linkandzelda_ | [18:44:05] <KotCzarny> Linkandzelda_: your normal current should be ~10mA <- this would be with screen off? | 20:51 |
| KotCzarny | yes | 20:51 |
| DocScrutinizer05 | yes | 20:51 |
| Linkandzelda_ | ok makes sense | 20:51 |
| Linkandzelda_ | then it has to be wifi i guess, only logical explanation in this case | 20:51 |
| DocScrutinizer05 | yes | 20:51 |
| KotCzarny | remember, crowded channels will wake the chip more often | 20:51 |
| Linkandzelda_ | i had xchat off the whole time before | 20:52 |
| Linkandzelda_ | oh, wait, my bad | 20:52 |
| Linkandzelda_ | wifi channels.. | 20:52 |
| KotCzarny | that's why i suggested scanning (can be with your lappy) to check which part of the radio is a bit freeer | 20:52 |
| DocScrutinizer05 | hmm? | 20:52 |
| Linkandzelda_ | and then i pick a free channel that other networks are not using much of? | 20:53 |
| DocScrutinizer05 | hmm?? | 20:53 |
| KotCzarny | usually your options are limited to 1/6/11 | 20:53 |
| KotCzarny | otherwise you get noise no matter what | 20:53 |
| DocScrutinizer05 | you're talking to somebody about setting up your AP? | 20:53 |
| Linkandzelda_ | current down to 32 | 20:54 |
| Linkandzelda_ | going to check out the other networks here | 20:55 |
| Linkandzelda_ | they are all using 1/6/11, both mine are using 11 and 10 | 20:56 |
| KotCzarny | um | 20:56 |
| KotCzarny | using 10 and 11 is not that wise | 20:57 |
| KotCzarny | i mean close channels interfere each other | 20:57 |
| Linkandzelda_ | i'll flip one of them over to 1 then | 20:57 |
| *** Avasz has quit IRC | 20:58 | |
| DocScrutinizer05 | dunno what you're doing but keep in mind you need a 2 free channels distance gap between used channels on WLAN, usually. Better 3 | 20:59 |
| Linkandzelda_ | god dammit, i have 3 APs in this place that belong to me | 20:59 |
| Linkandzelda_ | ok, disabled one | 20:59 |
| KotCzarny | just use 1 with guest/alt essids? some APs support multiple networks on single channel | 20:59 |
| DocScrutinizer05 | WLAN can cope with interferences but to avoid interferences and thus maximize bandwidth you need a gap to next used channel, left and right | 21:00 |
| *** krnlyng has joined #maemo | 21:00 | |

| Linkandzelda_ | channel 1 is very crowded | 21:01 |
| Linkandzelda_ | 6 has 3 on it | 21:01 |
| Linkandzelda_ | 11 has 4 | 21:01 |
| Linkandzelda_ | not sure how else to do this | 21:01 |
| KotCzarny | use 6 and 11 then | 21:02 |
| DocScrutinizer05 | http://my-maemo.com/software/applications.php?fldAuto=1241&faq=37 | 21:02 |
| Linkandzelda_ | does range matter in interference? | 21:02 |
| DocScrutinizer05 | yes | 21:02 |
| KotCzarny | yes | 21:02 |
| DocScrutinizer05 | of course | 21:02 |
| KotCzarny | too close and you get noise too | 21:02 |
| Linkandzelda_ | ok, all the ones in channel 1 are weak | 21:02 |
| DocScrutinizer05 | that's good | 21:02 |
| *** netkat_ is now known as netkat | 21:03 | |
| Linkandzelda_ | channel 6 has some ones that are stronger than the ones in my own house | 21:03 |
| KotCzarny | hehe | 21:03 |
| Linkandzelda_ | so i guess i'll go with 1 and 11 | 21:03 |
| Linkandzelda_ | ok, looking good | 21:04 |
| DocScrutinizer05 | install wifieye, I can recommend it. nice app | 21:04 |
| Linkandzelda_ | i will grab it | 21:04 |
| Linkandzelda_ | when i next turn on wifi | 21:04 |

| Linkandzelda_ | im going to turn on wifi | 21:07 |

| KotCzarny | whatever that is? | 21:11 |
| Linkandzelda_ | not sure what it is | 21:11 |
| KotCzarny | maybe someone packaged some different wifi driver | 21:12 |

| DocScrutinizer05 | al this supposedly leete stuff messes with maemo internals in a very obscure way and usually causes problems | 21:20 |
| DocScrutinizer05 | BT and USB should show up in your list of connections to choose from, when installed | 21:24 |
| DocScrutinizer05 | no reason to use any interface switcher for that | 21:25 |

| DocScrutinizer05 | and I made me a QueenBeecon applet to switch on/off WLAN auto-connect | 21:27 |

| * DocScrutinizer05 could figure just *one* interface handler app that's lacking and might be useful: reconfiguring GPRS to have none or invaid APN so the modem doesn't connect to GPRS connectivity at all, when you go 2offline" by whatever criteria manually or automatic. Since there's no other way to stop inbound traffic via GPRS, except going completely airplane-mode aka off with the modem, which would also block regular calls and SMS. | 21:57 | |

| DocScrutinizer05 | yes, your wifi is "borked" | 23:01 |
| freemangordon | hmm, check wifi power management, on the device that is | 23:02 |
| Linkandzelda_ | now since i turned on the screen, its down to 186 for the last 2 mins | 23:02 |
| DocScrutinizer05 | freemangordon: been there done that :-) | 23:02 |
| freemangordon | ah, ok | 23:02 |
| Linkandzelda_ | its ad medium now, i could put it back? | 23:02 |
| DocScrutinizer05 | you need to compare, but honestly I guess you're out of luck unless you get better AP or reconfigure the one you have | 23:03 |
| Linkandzelda_ | this is funny | 23:03 |
| Linkandzelda_ | http://sprunge.us/CZFD | 23:04 |
| DocScrutinizer05 | http://www.techworld.com/mobile/a-guide-to-wi-fi-power-save-technologies-4103/ is realy worth a read | 23:04 |
| Linkandzelda_ | 21:12 is when i went afk and left the screen off | 23:04 |
| Linkandzelda_ | 22:59 is when i returned | 23:05 |
| Linkandzelda_ | check the figures there, its idling at 350 but when im using it its lower | 23:05 |
| Linkandzelda_ | sense isnt made, unless im looking at the wrong column | 23:05 |
| DocScrutinizer05 | you're aware that negative mA are DIScharge while positive are charging? | 23:06 |
| Linkandzelda_ | yea | 23:06 |
| Linkandzelda_ | wait | 23:07 |
| DocScrutinizer05 | and this is just battery, not complete system | 23:07 |
| *** SpeedEvil has quit IRC | 23:07 | |
| Linkandzelda_ | its charging now since earlier | 23:07 |
| Linkandzelda_ | its 68% | 23:07 |
| *** SpeedEvil has joined #maemo | 23:07 | |
| Linkandzelda_ | i thought this was how much current was being used | 23:07 |
| Linkandzelda_ | so really i should not charge it | 23:08 |
| Linkandzelda_ | to get accurate figures? | 23:08 |
| DocScrutinizer05 | so 21:10 and 21:11 you either disconnected charger or system drew more power than charger been able to deliver, so it used battery to fill in | 23:08 |
| DocScrutinizer05 | yes, this is plain battery current | 23:08 |
| DocScrutinizer05 | system and charger are 'on the one end' and battery 'on the other end' | 23:09 |
| Linkandzelda_ | oh, so the higher the positive number while charging the less usage? im getting overly confused | 23:09 |
| DocScrutinizer05 | basically yes | 23:09 |
| Linkandzelda_ | then i'll leave it to charge 100% and take it off power | 23:09 |
| Linkandzelda_ | then will messure how much current it pulls | 23:09 |
| DocScrutinizer05 | while charging you can't tell about system power consumption | 23:10 |
| Linkandzelda_ | i should have known that earlier, that was a waste of time lol | 23:10 |
| *** M4rtinK2 has joined #maemo | 23:10 | |

| Linkandzelda_ | its no problem, i learn new things every day with this device | 23:12 |
| *** SpeedEvil has quit IRC | 23:13 | |
| Linkandzelda_ | so a mA of 0 is no charge and no discharge | 23:13 |
| DocScrutinizer05 | yes | 23:13 |
| *** SpeedEvil has joined #maemo | 23:13 | |
| Linkandzelda_ | so with brightness full + wifi i'd expect a -350 mA? just want to confirm that | 23:13 |
| DocScrutinizer05 | and still the system may be on | 23:13 |
| DocScrutinizer05 | yes | 23:13 |
| Linkandzelda_ | ok | 23:14 |
| Linkandzelda_ | i will look out for the numbers its discharging at then | 23:14 |
| Linkandzelda_ | after it charges | 23:14 |
| DocScrutinizer05 | when not connected to charger (or calibrate script disabled charger) | 23:14 |

| Linkandzelda_ | its my error | 23:14 |
