Ola, I took out an old relay from the cupboards, opening it to try to put OBK in, the chip is called WA2. By searching on the net it would be under BK7231 I flashed the module everything went well, but after the first boot no AP is displayed. I don't understand

This is not a BK7231N, but one known as BK7231Q. It is not supported anywhere afaik. There is only libretiny, but it has only minimal support done, not even wifi works. The only solution, i believe, is to swap it to WB2S, CB2S or ESP-02S.

Do you have a 2MB flash dump to share?

I have the dump of the basic software if you want
