Hi All!
I have previously used succesfully Arduino Uno + Arduino GSM Shield to receive SMS, but now with the newer Arduino Uno and Arduino GSM Shield 2 R3 all I get from received SMS is a HEX-coded string.
For an example string "123AB" I send from phone is dislayed like this in the ReceiveSMS sketch example:
SMS Messages Receiver
GSM initialized
Waiting for messages
Message received from:
+35840xxxxxxxx
00310032003300410042
END OF MESSAGE
MESSAGE DELETED
How do I get my new Arduino R3 + GSM shield 2 R3 to output text not HEX???
