Receiver has ExpressLRS 3.3.2 preloaded with binding phrase “123456”, the Receiver will never enter binding mode if using the traditional binding procedure. 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 30s, 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

Disconnect ESC and servos from receiver first. Wire the receiver into the USB-TTL adapter, with TX(PWM 2 pin) on receiver connected to the Rx on the USB-TTL, and RX(PWM 3 pin) 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. Press the boot button while powering on the receiver, then release – the Red LED on receiver should now be solid on. In configurator, Select the target Generic ESP32 PWM Vario 2.4Ghz RX, or RadioMaster ER6-GV and “UART” for Flashing Method, set your bind phrase and Firmware Options , Check “erase before flash” and “Force FLash “.
