35 0D 0A 5..the problems lies in this sequence:
- gateway sends sms (AT+CMGS)
- Modem sends unsollicited code (+CMTI)
- Modem sends prompt (>) as reaction to the +CMGS command
modem hangs in CME error 515 status (device busy), I can only recover the modem by restarting via AT+CFUN=1
I tried to simulate this case manually but then the unsollicited response comes only AFTER if the complete the CMGS command (PDU and CTRL-Z)
I think this is a wavecom bug. The CNMI setting is 2,1,1,0,1. Firmware is R74_00gg.FSU005 (modems were initially in R73, I upgraded the firmware to see if made a difference)
Please help me!
Cheers,
Kris
