Hello all,
As the title suggests, does anyone know if it's possible to get a list of all client IP address connected to an ESP8266 configured as an access point (ie: wifi.SOFTAP) ?
In my case, all the clients will be other ESP8266 devices. So one option I have is to configure each client to send it's IP address to the master ESP8266 on connection. The master then keeps a record. The problem is what happens when a client disconnects without telling the master...?
For context: the reason I want to do this is to enable the master to send a message to all connected devices (which have all set up their own servers). One way could be to just try and connect to all devices between 192.168.4.2 and 192.168.4.255, letting it fail when a client doesn't exist with a certain IP, but this doesn't feel very efficient.
Cheers, any thoughts welcome.
