Unsupported Watch - instructions to tinker with them

[arthurlutz]

I get the following message when trying to flash the device I bought :

The connected device is not supported! Its either not using a Telink Chip or uses a different OTA method

I had a fair warning in the video, not all devices work the same, so no surprises there.

Any indication on how to go about support the devices I got ? Should I open them up and see which chipset is being used ? Is there any information than can be useful "just" from BLE ?

Poking around I found some information that might be related : @dalenunns did some reverse engineering on a similar device https://xor.co.za/post/2022-11-30-hacking-smartwatch/

There are by now 3 Different Types of the watch sadly,
Most likely you got a PHY+ one which currently has no custom firmware, it is still on my list but will take a lot of time to finish
