Lilygo T watch 2020 ve

The unit arrived in a solid package with an instruction sheet. However, I tried to program it according to the instructions, but regrettably quite unsuccessful. I ventured into VSC, PlatformIO, Arduino. That brought me into a frenzy process of updating, reading of codes, rebooting etc .. I contacted customer service, and the replies were swift. But today, I am still trying to get the features working after various installations. I am still learning new processes, and it has been a pretty steep learning curve. Hence if anyone is planning to purchase this, you should have basic knowledge of Arduino and be prepared to spend time with the PC. It is not a straightaway process, though it can be interesting and challenging.

Not compatibility

Really hard to setup the envirionment to code watch with c++ arduino ide, and there is not any working library for micropython.

lack of documentation

The product is very good but there´s poor documentation, for example how to make your own usb connected sensor. You can run out of the box some examples but further is really a challenge, that would be less painful if some written docs are well mantained.
