6.7 FAST NETWORKING PROTOCOL
When the WIFI serial server is operating in AP mode, it will open a UDP port for receiving fast
networking protocol commands, with a port number of 49000. The mobile phone can be directly
connected to the WIFI network of the WIFI serial port server, and can query the SSID information list
and set the router SSID and password through the commands under UDP protocol. After the setting is
completed, the WIFI serial server will automatically restart and connect to the router, and it will work
in STA mode at this time.
Protocol format description:
