I'm using my ESP in WiFi.mode(WIFI_AP).
Is there any way to limit the number of allowed connections?
To be specific I'd like not to have more than one client connected at the same time.
Thanks!

See line 111 of https://github.com/esp8266/Arduino/blob ... WiFiAP.cpp

You'll either have to change the lib file, or easier, just write your own set ap config function, along the lines of:

Code: Select allstruct softap_config conf;
wifi_softap_get_config(&conf);
conf.max_connection = 1; 
ETS_UART_INTR_DISABLE();
ret = wifi_softap_set_config(&conf);
ETS_UART_INTR_ENABLE();   


So read the current config set through the usual method, and merely change the max_connection parameter.

I can still connect more than one client, should I report this on github!?
thanks anyways!

your solution works like a charm!!
thank you very much!!!!
