Question

we´d like to use the  TRB142 for a existing SMS Application with RS232

we need the comands AT+CMGR=1, AT+CMGF=1, AT+CMGS="+49...."

does the TRB142 support these comands?

e.g. for  AT+CMGR=1 we do not get the correct response

AT+CMGR=1

OK

should be e.g. for empty memory 1

AT+CMGR=1

+CMGR: 0,,0

OK

pleas let us know if there is solution

Hello,

You will need to check which modem your TRB142 uses. For example, I have a Quectel EC21-EU modem in my TRB142 and it does support these commands. When you know which modem you have, refer to Quectel manual how to use these commands: https://www.quectel.com/UploadImage/Downlad/Quectel_EC25&EC21_AT_Commands_Manual_V1.3.pdf

Regards.
