I am using Groov Rio module.
I want to perform serial to USB conversion. I have configured serial port in Node RED.
and on the hardware side I have connected serial to USB convertor IC(FT232).
On Hrdware side I have shorted Rx-TX Pin so that I can get sent data back.
in debug msg I am able to send data but not receiving it back.
Do we have any example of Serial to USB conversion?
