4. Setup

4.1 Protocol Switching

The G-129 supports two protocols: ELRS 2.4G (Firmware v3.0-3.3) and APEX's autonomous TX protocol. To switch between protocols:

1. Ensure the device is powered off.
2. Press and hold the FN key and the power button simultaneously.
3. Listen for beeps: a quick four beeps indicate the APEX TX protocol, and a slow four beeps indicate the built-in high-frequency head ELRS 2.4G protocol.

Note: After connecting to an ELRS protocol-based aircraft, it is necessary to configure the settings via the corresponding ground station; otherwise, the remote control may fail to function.

4.2 Connecting to FPV Simulators

The G-129 supports both PC and Android mobile FPV simulators without requiring a dongle.

• For PC: Connect the G-129 to your PC using a USB-C cable. The controller will be recognized as a joystick for simulators like TYPEFPV, Uncrashed, or DJI Virtual Flight.
• For Android: Connect the G-129 to your Android phone using a USB or OTG cable. You can then play FPV simulators available on Android.

6. Firmware Upgrade

Firmware upgrades are available through the ApexFlight ground station application. This process is not recommended for beginners.

1. Download the ApexFlight app from the Google Play Store.
2. Connect your phone to the remote controller via USB or OTG cable.
3. Navigate to the firmware upgrade section within the app.
4. Follow the on-screen instructions to upgrade the firmware.

Important: During the firmware upgrade, the phone must remain connected to the remote controller and should be kept charged to prevent the remote from malfunctioning if the phone shuts down.

8. Troubleshooting

• Binding Issues: If the controller fails to bind with your drone, ensure the correct protocol is selected (ELRS or APEX TX). For ELRS, verify ground station settings. Consult your drone manufacturer's instructions for specific re-pairing methods.
• Simulator Not Responding: Ensure the USB or OTG cable is securely connected. Try a different cable if issues persist. Verify that the simulator software recognizes the controller input.
• Firmware Upgrade Failure: Ensure your phone remains connected and charged throughout the upgrade process. Interruption can cause malfunction.
• Battery Draining Quickly: Check the 4 battery indicator lights. If battery life is significantly shorter than expected, ensure the controller is fully charged before use.
