no connection to wifi, and self resets..

[yo2ldk]

after flashing, work it some hours, then I cannot have access to app via wifi because module it not was connected anymore..
when I got it to pc, I see name was like after flash, but some settings it was like I made it.. Oh, and it have I2C BME280 sensor, but I cannot see it on map, just in app
very strange; I give one more chance / try
