SmartConfig is a way to communicate SSID/Pass from a device already on a wifi network to an ESP module that would like to join that same network, but does not yet know SSID/Pass. At its core, two pieces of information get transmitted: BSSID of relevant network (part of packet metadata) and Password hidden in packet lengths.
Question:
Is there a way to send a custom payload along with the password? I'd like to transmit host/port for the ESP to connect to, once it is on the network.
