Checking for Updates

1. Navigate to Settings → Firmware Update or tap the firmware notification if shown.
2. The app checks for available firmware versions.
3. Available updates show the version number and changelog summary.

Update Methods

OTA (Over-The-Air) via Bluetooth

The most common update method for Android users:

1. Ensure your radio is connected via Bluetooth.
2. Navigate to the Firmware Update screen.
3. Select the desired firmware version.
4. Tap Update to begin the OTA process.
5. Wait for the update to complete — do not disconnect during the update.

⚠️ Warning: Interrupting a firmware update can brick your device. Ensure your radio has sufficient battery (>50% recommended) and maintain Bluetooth proximity during the entire process.
