Hi everyone,
I would like to make a watermeter with an Arduino Mega2560 and a GSM shield. The purpose would be to send the data from the watermeter to a database on a server through electric pulses that the meter sends to the Arduino Mega. Does the GSM shield have a MAC-address that can be send together with the data? This so that I could eventually install multiple watermeters and I would verify them with their MAC-address.
