Hi Friends, This is my first post , I'm trying to interface a GSM module with the arduino UNO board. I found that the Tx pin (pin 3) or pin 1 (for hardware serial ) both are loading . Can you guys help me out with this problem? Thnks in Adavance Santu

Tx pin loading for both SoftSeraial and Hardware serial

Is there any interfacing mistake I'm making it??

Aside from not posting a picture of your setup or any code? Can't think of anything else that might be wrong.
