Binding ELRS Receiver
Gunduy is compatible with any Express LRS (ELRS) receiver. There are several different methods for binding a receiver.
Traditional Binding Procedure
Power off your transmitter/radio.
Power-cycle the receiver 3 times.
Supply power to the receiver.
The receiver LED lights up.
Turn it Off.
Repeat 2 more times.
Make sure the LED is doing a quick double-blink, which indicates the receiver is in bind mode.
Power up your transmitter/radio
Hold the
Button to open the tools menu.
Select ExpressLRS
Select
[Bind].The Popup will briefly show up and then disappear.
Hold
to leave the menu.
If the receiver LED turned into a solid light, it's bound!
Binding Phrase
You can select a short and simple Binding Phrase for your devices before flashing or updating using the field in the ExpressLRS Configurator.
Alternatively, you can also change the Binding Phrase via the WebUI if your device has WiFi capabilities and is already updated to ExpressLRS 3.0 or newer. See this page for the WebUI User's Guide.
We recommend using a unique phrase with at least 8 alpha-numeric characters. This phrase need not be complicated or super-secret as it isn't a password or encryption key.
By default, Gunduy is configured with GUNDUY as its binding phrase.
