Hmm, I still don't seem to be getting any data out of the RS485 port. I have it connected to a known working RS458 to USB on my computer, and I'm not seeing any data on my serial terminal (all set for 9600, 8N1).
What board definition should I be using in the Arduino IDE? I'm currently using 'ESP Dev Module'. I'm wondering if Serial2 is using the correct TX and RX pins for this board.
Thanks again!
