is it possible to do Modbus RTU / RS485 Communication via Micropython on XBee3 Pro?
There's the D7 (DIO7) setting that enables RS-485 communication either idle high or idle low. But I cannot find any documentation on how to send and receive the hex commands.
I assume that this must all be done via the primary UART serial line (the only one for XBee3) and using a logic level converter (for higher voltage on the slave RS-485 lines).
Been searching with combinations of "xbee, micropython, modbus rs-485". Only thing I can find is a micropython-modbus library which requires "from machine import UART" which XBee3 doesn't have.
Any help is appreciated. Thank you.
