Really, the most probable cause is your password is too short. Please try a password that is at least 8 characters.

I will add a check on that in the code.

Interesting, there is already such a check.

Can you try this: enable debugging (fs print-debug and then cw and then r). And then capture what's written to the UART. It will tell what SSID/password is actually used.

BTW it's never required to overwrite all flash memory, overwriting the config area is sufficient, for a "regular" (non-OTA) image that is 7a000 - 7afff. It wil revert to the default ap initial mode.

Ok I will test this.
Could you try for me one more thing?
Do you have problem with restart clients?

I reset clients (connection) few times and after 3'th and more reset i have connect to wifi network (got ip) but no data receiving from server (from uart in server)
Could you test it? Do you have the same?

What is your exact setup? Are you using tcp or udp connections?
