The factory firmware version of HGLRC ELRS GEMINI RX dual receiver is 3.X or above. 3.X and 2.X firmware are not compatible, so the TX Module firmware needs to be upgraded to 3.X and above before binding;
1. The receiver is powered on and off 3 times continuously (power off after the light is on)
2. Observe the RGB light of the receiver. After starting from the rainbow gradient, it turns into an orange double flash state, indicating that the receiver has entered the binding state.
3. Use the ELRS remote control or TX Module to link to the receiver. If the RGB light of the receiver changes from double flashing to solid, it means the binding is successful.
