Inside the box of dash lines is what we are trying to achieve. And in this doc, I am going to take RadioMaster Ranger and the RadioMaster RP1 as an example to show you how to set up the ELRS AirPort on TX and RX.
Configure AirPort
Step 1 - Flash the latest version of ELRS onto both devices (v3.3.0 onwards)
If you don’t know how to do that, you can take a look at this page Set up ELRS between controller and receiver
Step 2 - Enable the WIFI on the TX module
By plugging RadioMaster Ranger into power and waiting for 60 seconds, the devices would enter WIFI mode. For Ranger, this can also be achieved by long pressing the button and switching the mode to WIFI mode.
