Hi Shreya,

It may be due to the long distance, you can use copper cable for testing again.
And could you grab the RX / TX waveform on the error frame?

Best Regards

Johnson

Hi johnson,

Thanks for response ,but we are using RS-485 port for communication and also in some meters with 19200 baud rate it working properly ,

can you send me the RS485 setting of UART with baud rate 19200 and 1MHz clock frequency so that i can cross check my registers setting
