Overview
Firmware updates address compatibility and reliability issues. Use the official in-app update flow only.
How updates are offered
- Auto-prompt — once a Compass Series device is paired, if a firmware update is available, Navigator Mobile prompts you to install it.
- Tools tab — the firmware version row exposes an update option whenever the version is outdated.
Before you begin
- Adequate battery on both phone and device.
- Stable Bluetooth proximity for the duration of the update.
- Identify model and hardware version (V4 vs V5+) on the Tools tab if you escalate.
Update
- Tap Update from the auto-prompt or open Tools and tap Update on the firmware row.
- Read warnings; do not force-quit the app or move out of Bluetooth range mid-phase.
- Keep the phone on with the app open for the duration of the update.
- Wait for completion; verify the firmware version changed as expected.
- Validate Voltage and Current tab readings and the heartbeat after any post-update reboot.
