Bind Procedure:

1. Supply power to CrazyF4 ELRS flight controller (Plug the USB), wait until the RX LED is off, immediately turn off the power (Unplug the USB), and then repeat the above steps again. When the RX is powered on for the third time, the LED light will start to double-flash, which means that the RX enters into the binding mode

2. Insert the ES915TX module or other DIY 2.4G ELRS TX to your OpenTX Radio transmitter, and choose External RF mode to CRSF protocol, then you can find ELRS menu from the Radio system (Need to copy the ELRS.LUA file to the SD-Card tools first), Enter into ELRS and press [Bind], the RX LED on the Flight controller will getting to be solid if bind successfully.

3. Receiver LED status meanings:LED solid means bind successful or Connection established; LED double-flash means in bind mode; LED flash slowly means no signal established with the TX module
