Flashing Tuya A5F-53F1-02 with TR6260S1 Chip: ESP-02S Pairing Issues

A5F-53F1-02 WIFI mini switch
Is it possible to flash this Tuya chip?
TR6260S1
I could not flash it. Maybe I used the wrong pin for boot mode?
But I did get some info in a sniff from RX2/TX2 pins.
See attached file.

Newbie but want to learn this stuff a little better
The chip is replaced with an ESP-02S and working with Tasmota.
{"NAME":"RS01-TAS-1","GPIO":[0,0,0,32,576,0,0,0,0,224,160,0,0,0],"FLAG":0,"BASE":18}
But it is lighting on 2 sec off 2 sec after pairing. Any solution?
Is there a standard? What info do you pros need?
I will gladly provide

TR6260 is not currently support, but we've already done some research and I think it may be possible to port OBK to this platform in the future. However, I currently do not have any TR6260 modules at hand so I can't do any testing. Futhermore, we would need to find a flash tool for TR6260, but I've heard it's possible to be done with at least SPI

It's normal, it's just blinking because you need to connect to Tasmota access point and configure it...

Anything I can do. Have equipment.
Did read a thread about. It could be needed to get info while on main.
I have a USB isolator ADUM3160 USB Power Isolation (enough?)
and SPI I have a XGecu TL866 II laying somewhere

New to IO, but okay in general.
Or I could send you a letter with 2 chips (I have 12 unsoldered) if it could make a big difference.
A letter from DK to PL is only 7€
Think I can survive that

Yes, sending few pieces of this modules could help a lot, especially when it comes to porting. Thank you. Send me a PM and I'll provide you data.

If you have some equipment and chips at hand, you can try checking the flash procedure yourself. We need to know is it possible to read and write the device flash easily and then we need to check if any of available SDKs are really working.

pm your way

Hello, @micbanand

Sorry for resurrecting this old thread but, as I have a device with the same module (TY-WE2S-A), and there has been some progress with it another thread you may not be aware of, I wanted to notify you and others that could be monitoring this one. See from this post onwards.

I see you also participated in this newer thread and posted photos of the same module, but it's now locked, so I cannot give this info there.
