i am trying to interface gsm shield and NI myRIO. I am using gsm shield v3.0. I am facing problems while interfacing. can anybody tell what are the uart pins (RX & TX) in gsm shieldv3.0. It will be helpful for me.
In GPRS shield v3.0 the uart pins are as follows
for software serial
for hardware serial
Select them using the jumpers available in the board.
Please refer the wiki page for more information.
Thanks and Regards
