RILd

[Gianmaria Iaculo]

Hi,

I'm using BBB with android 4.4.4_r1. I have all set for RIL but on logcat i continue to receive this message and nothing else:

root@ubuntu:~/aosp# adb logcat -b radio

Someone have a solution for this?

This is my idea also, but ho to set the right permission in unit.rc? 

Also... It seem like the ril works like a phone in airplane mode. Set the cfun to 4 and does nothing else later... Also my hui interface have no gsm status... 

Very tricky....

Thanks,

Gianmaria

Could it be either linux permissions or selinux permissions limiting access /proc/cmdline?

At a guess I'd suggest adding the following line to your ueventd.rc

/dev/ttyACM0                 0660   radio      radio

Hi Gianmaria,

the Java part of the RIL (not the Telit one) is responsible to send the power request to put the modem in +CFUN=1.

The Telephony manager error should not be related to what you are experiencing.

Anyway, my advice is to contact Telit customer support: I don't think that anyone can help you here without source code (and Telit RIL is under NDA, so you cannot share it).

Regards,

Daniele
