Firmwares:
- Receiver Target (all target options below will work):
- Generic ESP32 PWM Vario 2.4Ghz RX
- RadioMaster ER6-GV
- RadioMaster ER6-G
- 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 here.
- 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“.
