Ok I have the explanation.
Esp32 itself makes low level at +1V and high level at +3,3V
Your hav2 board is a real rs485 level. +1,5 and - 1,5v
So you cannot use an esp32 mcu directly in the rs485 bus.
You have to tell this thing in the presentation video of the hav2 board. I have purchased an uart to rs485 and I will try to add it to the circuit and see what happens.
I will update you.
Thank you
