• You need to reflash it with your binding phrase OR connect it to your PC/phone via WiFi and set your binding phrase in WebUI.

Tips

• Full Resolution Switch Configuration Modes
• Powering receiver with Reverse Voltage will damage the regulator chip. DOUBLE CHECK the power wires connected to the receiver.
• Transmitter fw version should be EdgeTX 2.7.1/OpenTX 2.3.15 or newer

Flashing via Wifi

• Power on receiver. Receiver’s LED(Red) will blink slow at first, and after 20s, it should blink fast indicating it’s on Wifi Hotspot Mode.
• Wifi SSID “ExpressLRS RX”,  Password “expresslrs”
• More detailed steps,  pls refer this page.

Flashing via UART

1. Disconnect ESC and servos from receiver first.
2. Wire the receiver into the USB-TTL adapter, with TX on receiver connected to the Rx on the USB-TTL, and RX on receiver connected to the Tx of the USB-TTL. Wire 5V and GND of the USB-TTL to “V” and GND of the Receiver.
3. Press the boot button while powering on the receiver, then release – the Red LED on receiver should now be solid on.
4. Configurator 1.6.x or newer,  Select the target Generic targets used as a base 2.4 GHz  –> Generic ESP32 PWM Vario 2.4Ghz RXX  and  “UART” for Flashing Method,  set your bind phrase and Firmware Options , Check “erase before flash” and “Force FLash “.
