And as I said before, if you reset a device without closing the socket properly, the other end of the socket will keep waiting for the socket to become closed for some time until it timeouts. So either don't reset but close the socket properly or use UDP, which is designed for that use.

Maybe you have right, i try find solution for that.
So is a little strange, the same client on HLK module works perfect.
I will try close socket to the end of send data.

In client mode can the ESP8266 connect to a hidden SSID?

No, hidden SSID's are not supported. There is no use for it.

Security guidelines for Home networks recommend hiding the router SSID.

I want to use this to WiFi-enable a legacy home automation device. The device uses RI (Ring Indicator) to wake a sleeping PC. Will your firmware relay RI via WiFi?

Also, for one device, it would simplify things if the serial signals could be active high. Is this possible?
