Is there an easy way to check if a device is esp or beken without opening it up?
Well if you connect it at Wifi the mac address of device might help as you can check if it’s part of Expressif ones !
Tasmosta database might help too: https://templates.blakadder.com/
Checking MAC address…good idea.
Thanks
If you end up down the Beken route and you want to proceed, you will probably still need to figure out the specific chip that is being used and whether either of the firmware replacement methods support the chip and firmware rev.
Unfortunately getting good with a spudger tool is need to have in your quiver
Good hunting!
