adb error
$./adb shell error: device offline
New android require adb authorization upon first connect, authorized pc's file live in /data/misc/adb/adb_keys
So if you have error that device offline either you have old adb version or not authorized.
Make android code support old and current android api

rfkill mystic
rfkill устройства оказывается гуляют туда сюда между rfkill0 и rfkill1 для gpio и bt, это создает всякие странности в работе обоих когда ставятся не правильные права, т.к. в андроиде прописано жестко на какое устройство какие права ставить (юид и гид)

Марвин в курсе, что такое может быть, но пока не знает как пофиксить
[01:22] <zombah> marvin24: hello, i noticed that sometimes rfkill0 and rfkill1 change their names between hci0 and wifi_rfkill and in rare cases rfkill2 appear with name phy0, is this ok or im missing something? [01:36] <zombah> marvin24: i mean, now i just rebooted and wifi_rfkill is rfkill1, but how this happen because i thought it always must be rfkill0 [01:39] <-- ojn покинул(а) сервер (Remote host closed the connection). [01:44] <marvin24> zombah: could be [01:44] <marvin24> I didn't looked for a better way to connect rfkill to thier devices [01:44] <marvin24> and I don't have a bt model [01:44] <zombah> marvin24: ohh is it possible to always bind to rfkill0? android need to set specific permissions adn they differ for bt and wifi [01:45] <marvin24> there must be some method [01:45] <marvin24> but again, I didn't looked into it yet [01:45] <woglinde> he marvin24 [01:45] <zombah> i see, i will search other examples, thanx [01:46] --> styopah вошел на канал ([email protected]). [01:47] <marvin24> we have a similar problem for rtc [01:48] <woglinde> hm? [01:48] <marvin24> because the regulator and the tegra soc supplies a rtc device and it is just random which one get which [01:48] <woglinde> oh [01:48] <woglinde> damn [01:48] <marvin24> and system seems to use rtc0 as a clock source by default [01:48] <marvin24> so sometimes date works, and sometimes not [01:48] <woglinde> I thought we wanted to use the one from the tps [01:48] <marvin24> you can only force module load in the right order [01:48] <woglinde> and disable the other [01:49] <marvin24> you should be able to enable all supported hw [01:49] <woglinde> ? [01:49] <-- styopah покинул(а) сервер (Client Quit). [01:49] <marvin24> I think this is a common problem for many device, so there must be a simple solution [01:49] <marvin24> maybe udev or so [01:49] <woglinde> if the tegra rtc is not usefull why not disable it [01:49] <marvin24> it is useful [01:50] <woglinde> hm [01:50] <marvin24> it just starts art 1.1.1970 at every system start [01:50] <zombah> andoroid lack udev support [01:50] <marvin24> maybe there is some other method [01:50] <woglinde> how is that usefull if the tps rtc has the right date [01:54] <marvin24> if you only need relative time chances [01:55] <marvin24> and I guess the tegra rtc is more accurate in short term [01:57] <marvin24> often some other device properties are use to define the device id [01:57] <marvin24> e.g. mac address or serial number [01:58] <marvin24> but this doesn't work for a gpio only ...
