Touch dev question: enabling wifi on demand?

jape · 03-04-2012, 05:52 PM

Any dev types know if I can enable wifi on demand somehow with the kobo touch? I've enabled telnet and what I'd like to do is browse around the device to look at the logs and use evtest to see if the touch driver is still generating events when touch input fails.

Every few days touch input stops respoding and I'd like to see if I can debug this further.

The problem is that the device shuts down wifi to conserve battery (presumably) and the only way I know to force wifi on is to launch the web browser but obviously I can't do that if touch input has failed.

I'm wondering if its in the realm of possibility that I could somehow listen for a double click on the home button and cause that to kick wifi (or maybe launch the web browser?).

Any thoughts?

It sorta looks like this process is related to the network access, since I lose connection when I kill it:

978 root 0:00 wpa_supplicant -s -i wlan0 -c /etc/wpa_supplicant/wpa_supplicant.conf -C /var/run/wpa_supplicant -B

but running that command doesn't seem to be sufficient to enabling wifi access.

Take a look at http://hostap.epitest.fi/wpa_supplicant/ and take a look at the README for info on how wpa-cli works,

Thanks for the pointer. I have a script which can execute a command in response to a long press of the home button, but for some reason when I try to run the wpa_supplicant command it seems to die immediatly with no info to stdout/stderr.
