Receiving SMS Messages

Thank you for the reply. I have used the send methods to send various AT commands. Still not able to read any of the SMS messages. I have tried the following commands to list, read, and send CMGL, CMGR, CMGS. Responses have been inconsistent. I have tried clearing the messages from the sim and device using CMGD.

Now I’m not able to send using the send sms example. Here is the output using the example code (last 4 of phone number redacted here but not in output)…

Sixfab Raspberry Pi Cellular IoT Shield Class initialized!
BG96 module disabled!
BG96 module enabled!
BG96 module powered up!
ATE1

OK

AT+CMGF=1
AT+CMGF=1
OK

AT+CMGS=“176081XXXX”
AT+CMGS=“176081XXXX”

hello world!











---- End of output

It seems the final send command fails and just re-attempts. This send method was working a few days ago and now all I get is the above response. Is there a way to reset the modem back to original settings?
