Hi all,
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.
Hi,
In GPRS shield v3.0 the uart pins are as follows
for software serial
Rx------>7
Tx------->8
for hardware serial
Rx------>0
Tx------->1
Select them using the jumpers available in the board.
Please refer the wiki page for more information.
Thanks and Regards
