Hello, This is Souvik. We were testing the RC7620 module using mangOH red evaluation board. We were successful in testing for call functionality using AT commands but while testing for SMS and HTTP, we were encountering a certain error with error code as +CMS ERROR: 305 while passing the commands
+CMS ERROR: 305
We have tried several iterations of the same even by changing the syntax of at+cmgs=“8178743739” to at+cmgs="+918178743739", yet the result was an error as mentioned above.
Any help regarding the same is greatly appreciated. Thank you.
