The effect of (a) is the modem only answers "ERROR" to the +CGDATA="PPP" command. I have tried different commands to reset the internal state, but it was stuck, only a power cycle could solve this. I have added an automatic power cycle for this situation, but it didn't occur again yet.
My modem has been in the powered-off state for quite some time because I have only been testing on the bench where I have wifi connectivity. Today I installed the module in my Roadster to test some metrics as requested by Greg, and when I plugged it in I saw the blue modem light come on. After I did my test and removed the module to bring it back in and connect to my laptop, the blue light is still on. About every 20 seconds I see this cycle repeating: I (43342) simcom: State timeout, transition to 1 I (43342) simcom: State: Enter CheckPowerOff state I (54352) simcom: State: Enter PoweringOff state I (54352) gsm-ppp: Shutdown (direct) I (54352) gsm-nmea: Shutdown (direct) I (54352) simcom: Power Cycle I (54352) netmanager: Interface priority is st1 (192.168.1.84/255.255.255.0 gateway 192.168.1.254) A command "simcom setstate PoweredOff" is not effective. -- Steve
