Suppose, I have 2 ESPrtk modules.
They have Device ID respectively xx_B, xx_R.
I will configure xx_B as Base station.
xx_B will collect RTCM data on port RX_UART1 from RTK receiver and send it to the Rover.
xx_R1 is Rover, it will receive RTCM data from xx_B and Stream to port TX_UART2.
The password for this model connection is kml-123_KLM
Because WIFI-UDP on version 2.4.1 only supports up to 1 connected device, Device IDs are no longer needed. Users need to know that Rover is xx_R, and the main Base is xx_B.
