Hello,
To avoid other people to be caught in that trap, I think it’s very important to report here Pycom company behavior, manufacturer of non-working ESP based devices. It’s very sad as their products look really promising but nothing works, no support and products detailed specifications can’t be found preventing you to install alternative firmware like ESPhome . They have quite a bad history already on a crowfunding website (I won’t name crowfunding website as it’s also an swindler but easy to find) and checking history of company, it’s part of companies that don’t leave in real world (they would have disappeared very quickly) but on funds of generous sponsors… so don’t even consider their fake products that don’t work
Hope it’ll prevent other people to be caught into that,
Vincèn
