I am trying to communicate wirelessly using two holybro 433 MHz telemetry modules. My main objective is not to use the pixhawk but to communicate wirelessly between two computers. I am able to send characters from one module to another and view the result on putty. However, the displayed characters are garbled. I have confirmed the baud rate, parity and number of bits are the same on both modules. This is the first time I am using these modules. Am I missing something?
