Hi,
I am trying to use a sierra wireless modem on android and i
encountered the same problems as you did and resolved part of those
with this procedure:
hardware/ril/libril/ril.cpp
First #if 0 to #if 1 Removes can't connect to rild socket, but now we
have can't connect to rild-debug
Comment next #else Removes can't connect to rild-debug socket
hardware/ril/rild/rild.c
/* special override when in the emulator */
#if 1
{
to
/* special override when in the emulator */
#if 0
{
/system/core/init/devices.c
{ "/dev/ttyACM0", 0660, AID_RADIO, AID_RADIO, 0 },
/init.rc
loglevel 4 instead of 3
service ril-daemon /system/bin/rild -l /system/lib/libreference-ril.so
-- -d /dev/ttyS0
I still have some issues though: it seems that either my igep board or
the sierra wireless modem is too slow for the other as i have several
AT ERRORS (see log http://pastebin.com/YRJBfBYV). Any help on this log
will very much appreciated.
Plus i am trying to find info on setting up APNs.
