I've got an XBee to RS485 adapter communicating to a ConnectPort gateway using Python.
I can send data from the gateway to adapter using the loopback Cluster ID 0x12.
I can also send from my RS485 device to the gateway.
But so far I've been unable to send from the gateway to the RS485 device.
I'm sure it has something do do with flow control, but I haven't had any luck finding documentation on how to implement flow control from python. I did find docs on configuring the D7 setting:
Any ideas on how to implement flow control for XBee to two wire RS485?
