Trying to send an SMS message using the 9-pin serial port. Here is the example given <<<15105554200,ASCII,12,54657374206d657373616765>>> (I change the cell# to mine).
and no message is sent or error on from the serial software (I’m using RealTerm), and it seems to be connecting correctly with 115200,8,1,N settings.
Is there a step by step example for this?
Thanks
