What response do you get when you issue
AT+CMGD=1,4
?
The screenshot of the monitor does not match the code.
Where does Serial.println("AT+CMGD=1,4"); get printed?
The SMSFULL message is probably occurring as there are text messages waiting to be received.
Remove the commands from the setup routine, and type the command at the Serial Monitor prompt - what do you receive?
I use
MODEM.send("AT+CMGD=0,4");
MODEM.waitForResponse(5000);
if you want to do it in the sketch. Maybe the u-blox m-connect software could help to debug.
And it work?
Yes, why not? Depends if there is a sms in the memory. The modem answers with OK if sms are present or ERROR with no sms on the AT console. You can see this on serial monitor if you call with (true) argument:
GSM gsmAccess(true);
Here is the manual:
Thx for you help
Next time you should read the manual...
RTFM... good rule to live by.
