Comfee Board

[fraschizzato]

Hi,
I have a Comfee CF-DEHU-12 without WiFi support. I've found that it has the internal connector but I can't get any data from UART (power is ok). I've checked the PCB routes and all seems connected (except from the lines that goes to the different display of other products, the "disp n5" on image).
The fact is that I don't have the WiFi toggle button, can someone check in their unit what the WiFi button does? I suppose that only pulls up or down on pin of the IC.
Probably a wire check of the display connector to see which pins are shorted could be fine.
For any one interested the IC is a SINO WEALTH SH79F161AF (search for SH79F161A, the F is a package version). Used pins are TXD, RXD, P2.7 (generic PWM or INT) and a blank one (probably GND)
Thanks

@fraschizzato did you ever figure it out?

[fraschizzato]

nope, as I remember my last check was about uart and it seems disabled by software
