Hi,guys:
I am porting android to smdk6410.now I want to send mms,but the
datacall can not be setup.
My wireless module is Huawei EM770W,the rild.libargs=-d /dev/ttyUSB0.
When apns-conf.xml is not added in system/etc/,the system can dial a
phone and send a sms;while apns-conf.xml is add ,I can see the GPRS
flag the topbar,but the signal state become gray which means that it
is connected but the signal is zero.
the LAST lines of logcat -b radio :

errer appears,should I delete this AT command in reference-ril.c?

Whether set it to /dev/ttyUSB0 or /
dev/ppp,they are the same ouput.

##############Question3:No response after AT+CSQ ,but before apns-
conf.xml being added ,I can see the response "D/AT ( 688): +CSQ:
14,99 ",so Why?Wrong PPP_TTY_PATH? pppd not started?
1659 D/RILJ ( 811): WAKE_LOCK_TIMEOUT mReqPending=0

1660 D/RILJ ( 811): 0: [9] SET_NETWORK_SELECTION_AUTOMATIC
1661 D/RILJ ( 811): 1: [61] SIGNAL_STRENGTH
then the logcat hangup.
The questions I want to ask are inside the logcat above.
Could you tell me what the problem is?and How to solve it ?
Maybe pppd should be started and initiated ,how to?
Thank you
