XBee3 micropython uart communication

0 votes

I am using XBee3 to communicate with a meter through RS485. Refer to https://www.digi.com/resources/documentation/Digidocs/90002219/#reference/r_uart_constants.htm?TocPath=Access%2520the%2520primary%2520UART%257C_____1, I access the uart via stdout.buffer.write() and stdin.buffer.read(). The meter able to receive modbus request that sent from XBee but the modbus response is not what I expected. I transmit the response to coordinator XBee to console out the reading as XBee3 modules only have one uart available. So I suspect by using stdin.buffer.read() method to read from uart is not safe as stdin stream will also contain other information that redirect to that stream. Am I correct?

No, these functions should work properly.
