Uart spam from display no sensor data

[alanv72]

I have this deployed on an esp32. I have uart debug on and as long as the display is connected I get spammed with this.... Which looks like valid traffic based on the protocol doc. However, when I pull the display off the comms go silent and nothing responds when the uart command is sent from esp32...

All sensor show "unknown"...

Log showing all the traffic when display is plugged in...

I switched to an esp8266 with a ttl to rs485 converter that doesn't have flow control pin. It is now working. Not sure what was wrong with the esp32.

Might try again sometime.
