Hi Everyone, I am new in this forum. I am working on how to transfer data through RF using serial communication. I bought Rf module (KYL500s). it is a transceiver. I first of all tested serial communication between two 8051. it can only work when I connect the ground together. Pls, how do I make it work without connecting the GND together? Also, is there any way I can ensure that my data is not affected by noise? Thank you
