so here’s what i’m sending:
"AT+CNMI=3,2,0,1",
"AT+CMGS=35\r0011000B814134471567F000000B17C8329BFD064D9B5362999DB697E565B96BFC6E8700\x1A",
/* Add more here if needed */
};
and here’s the output from the sms app when i press the button:
Button pressed at 952749
AT+CNMI=3,2,0,1
0011000B814134471567F000000B17C8329BFD064D9B5362999DB697E565B96BFC6E8700
and here’s a decent online URL to decode the message showing it’s valid: https://www.smsdeliverer.com/online-sms-pdu-decoder.aspx
still nada coming to my phone… interestingly, no response callback is called …
and if i type AT or press the button once more, i get an error and the modem is left in a weird state no longer accepting commands from the terminal:
0011000B814134471567F000000B17C8329BFD064D9B5362999DB697E565B96BFC6E8700. Error: -1.
and from that point until RESET it solely echoes back what i type to the serial port
