Getting help with BLE Inspector

Frequently Asked Questions

The app can't find my device.

Confirm Bluetooth is on and the peripheral is actively advertising (many sensors only advertise after a button press or wake). Move closer — BLE range is far shorter in practice than the 50m spec. Check the device is not already bonded to another phone/tablet, which can suppress its advertisements.

I can't connect to the device.

Some peripherals accept only one connection at a time — disconnect from any other app (or phone) first. If the device requires pairing, initiate pairing from the connect flow and accept the prompt on macOS. Bonded devices that have changed pairing keys may need the old bond removed in macOS Bluetooth settings before reconnecting.

Services or characteristics are empty.

Service discovery can take a few seconds after connect. Wait for the GATT tree to finish loading. If it stays empty, the device may restrict discovery until paired, or the service UUIDs may be vendor-specific — try a full discovery pass rather than filtering on standard services.

Writing to a characteristic fails.

Check the characteristic's properties — writes require the WRITE or WRITE WITHOUT RESPONSE property. Protected characteristics require an authenticated/encrypted link (pairing). For write-without-response, use that exact write type or the device will silently drop the value.

How do I enable notifications?

Open the characteristic, then enable Notify (or Indicate). The app subscribes to the CCCD and streams incoming values as they arrive, with timestamps. Notifications require the NOTIFY or INDICATE property on the characteristic.

My license key doesn't work.

Enter the full key including dashes (format: VOLTRUS-BLE-XXXX-XXXX-XXXX). An internet connection is required during first activation so the app can validate the key once. After activation, the app works offline. If it still fails, contact support below.

I bought from the Mac App Store. Do I need a license key?

No. The Mac App Store version is automatically licensed through your Apple ID. No license key needed. The paywall only appears in the direct-download (DMG) version.

I bought via Polar.sh but want to switch to the Mac App Store.

Purchases through Polar.sh and the Mac App Store are separate. We cannot transfer purchases between platforms. Both versions are identical in features.

The app crashes or freezes.

Make sure you're running macOS 13 (Ventura) or later. If the app freezes while connected, try disconnecting and reconnecting. If the issue persists, contact support with your macOS version, the app version, Mac model (Bluetooth version matters), and the peripheral you are testing.
