BINDING PROCEDURE:

  • Supply power to the PP/EP1/EP2 RX, wait until the LED on the RX is off, then immediately turn off the power. Repeat the above steps once again. After the RX is powered on for the third time, the LED light will start to double-flash, which means that the RX has entered bind mode.
  • First, copy the ELRS.LUA file to the SD-Card. Then, insert the ES24TX module or other 2.4G ELRS TX Module into the Radio Transmitter, and choose External RF mode to CRSF protocol. Find the ELRS menu, and select "ELRS", then select the [Bind] option. If the binding was performed successfully, the LED on the RX module will turn solid.
  • Receiver LED Meaning:
    • Solid: Bind Successful or Connection Established
    • Double-flash: Bind Mode
    • Slowly Flashing: No signal connection from the TX module
    • Quickly Flashing: WiFi Hotspot Mode*
*Once in WiFi Hotspot Mode, you can connect the WiFi of the RX and upgrade the receiver's firmware by opening your web browser and typing in "10.0.0.1". Use the password "expresslrs".
