All wifi module supports UDP search, they will return to their respective IP, MAC,
MID, detailed search process is as follows: 1. PC via UDP broadcast (broadcast address:
xx.xx.xx.255, Port: 48899) sent a password, the default password is: "HF-
A11ASSISTHREAD", the password can be used AT commands (AT + FASWD) set up, it's
Up to 100 bytes. 2. After the module receives a password, if the password is correct, to
the address (Unicast, Port: 48899) sends local IP address and MAC address and name of
the module. (IP, MAC, MID as 10.10.100.254,888 B5D0000E2, guxin). So you can get to
