I have noticed that sometimes (I noticed it only one time) WS6318 module malfunctions. I made it enter the data mode and send data to it but the module doesn’t pass it through (the Tx_Cntrl line is low - no blinking). It looped it back. I decoded the signal on the output UART line on the oscilloscope and determined that the output data is equal to input data.
Had anybody faced with such a problem?
Thanks a lot!
