Thank you, can you provide the pins configuration for that device?

I am creating multiplatform open source firmware (Tasmota replacement), right now supporting BK7231T, BK7231N, XR809, BL602, W800, W600, LN882H and soon supporting RTL and W701:

Well, you have either to look at the board and check traces with multimeter to see where things are connected, or just try pin roles one by one... you can also search for similar devices on our template list. https://openbekeniot.github.io/webapp/devicesList.html
