Hi Ram,

Please do not top-post on this mailing list.

I have just tried my HE910 with unmodified oFono 1.16 and I am able to 
successfully activate the context.

My firmware version is 12.00.003, but 12.00.004 is recommended.

What you should be seeing is something like this:

ofonod[19130]: drivers/atmodem/gprs-context.c:at_gprs_activate_primary() 
cid 1
ofonod[19130]: Modem: > AT+CGDCONT=1,"IP",""\r
ofonod[19130]: Modem: < AT+CGDCONT=1,"IP",""\r
ofonod[19130]: Modem: < \r\nOK\r\n
ofonod[19130]: drivers/atmodem/gprs-context.c:at_cgdcont_cb() ok 1
ofonod[19130]: Modem: > AT+CGDATA="PPP",1\r
ofonod[19130]: Modem: < AT+CGDATA="PPP",1\r
ofonod[19130]: Modem: < \r\nCONNECT\r\n
ofonod[19130]: drivers/atmodem/gprs-context.c:at_cgdata_cb() ok 1
ofonod[19130]: drivers/atmodem/gprs-context.c:setup_ppp()
ofonod[19130]: drivers/atmodem/gprs-context.c:ppp_connect()

What you are seeing is this:

ofonod[6586]: drivers/atmodem/gprs-context.c:at_gprs_activate_primary() 
cid 1
ofonod[6586]: Aux: < \r\n
ofonod[6586]: Aux: < +CIEV: rssi,5\r\n
ofonod[6586]: src/network.c:ofono_netreg_strength_notify() strength 100
ofonod[6586]: Aux: < \r\n
ofonod[6586]: Aux: < +CIEV: rssi,4\r\n
ofonod[6586]: src/network.c:ofono_netreg_strength_notify() strength 80
ofonod[6586]: Terminating

That tells me that the port detected as the 'Modem' port is incorrect.

ofonod[6586]: plugins/udevng.c:setup_he910() modem=/dev/ttyACM0 
aux=/dev/ttyACM3 gps=/dev/ttyACM5

Please check that those TTYs are indeed live and can accept AT commands. 
  If not, then you need to update firmware, set the appropriate PORTSEL 
setting or update plugins/udevng.c logic for detecting your particular 
variant of HE910.
