[quote userid="646799" url="~/support/microcontrollers/arm-based-microcontrollers-group/arm-based-microcontrollers/f/arm-based-microcontrollers-forum/1489213/ek-tm4c1294xl-tm4c1294ncpdt"] Lets say, if I use JSON frames in the payload, as key value pairs, based on the key part, could that be directed or redirected to different UART? Or based on the KEY part, could the message be used to initiate a sensor reading and send the readout as an answer? [/quote] I don't see why not. It is up to your application how to decode/parse a JSON frame and take appropriate actions for them.
