Receiver protocol: Serial-based receiver – CRSF

Traditional Binding

Receivers have ExpressLRS fw V1.1.0 preloaded without BINDING_PHRASE

1. Power on and off your receiver three times

2. Make sure the LED is doing a quick double blink, which indicates the receiver is in bind mode

3. Use the [BIND] button on the Transmitter Lua script, which sends out a binding pulse

4. Receiver will switch to slow blink once it has received binding pulse.

5. Power off and power on receiver again. If the receiver LED switch to solid on from slow blink, it’s bound with your transmitter.

Important

If the RX firmware has a bind phrase, the RX will never enter binding mode using the above procedure. It must be flashed without a binding phrase to do traditional binding.
