Quick Fix: Android Permissions
Most Bluetooth problems on Android are caused by missing permissions. Check all three before doing anything else.
| Permission | Where to Check | Required |
|---|
| Location | Settings > Location | ON (system-wide) |
| measureQuick Location | Settings > Apps > measureQuick > Permissions > Location | "Allow while using the app" |
| Nearby Devices (Android 12+) | Settings > Apps > measureQuick > Permissions > Nearby devices | Allow |
Why Location? Android requires Location for Bluetooth Low Energy scanning. This is an Android OS requirement, not a measureQuick setting. If Location is off, the app cannot find any probes.
After an OS update: Android may reset permissions during major updates. If probes that previously worked stop appearing, re-check all three permissions above.
Quick Fix: iOS Permissions
| Permission | Where to Check | Required |
|---|
| Bluetooth | Settings > Privacy & Security > Bluetooth > measureQuick | ON |
| Location Services | Settings > Privacy & Security > Location Services > measureQuick | "While Using the App" |
| Background App Refresh | Settings > General > Background App Refresh > measureQuick | ON |
Probes Not Showing Up
Work through these in order. Stop when the probe appears.
- Check permissions (tables above).
- Confirm the probe is powered on and not in sleep mode.
- Check if another phone is connected. BLE probes connect to one device at a time. If a coworker is connected, the probe is invisible to your phone.
- Move within 10 feet of the probe.
- Power-cycle the probe. Off, wait 5 seconds, on.
- Force-close and reopen measureQuick.
- Toggle Bluetooth off and on in phone settings.
- Clear app cache (Android): Settings > Apps > measureQuick > Storage > Clear Cache.
- Restart your phone. This clears the Bluetooth stack.
Probes Disappeared After Reinstalling the App
Reinstalling measureQuick clears all stored probe pairings. To reconnect:
- Open measureQuick and go to the test screen or Probe Manager.
- Power-cycle each probe (off, wait 5 seconds, on).
- The app will rediscover and reconnect probes automatically.
- If a probe does not appear, its internal pairing list may be full. Use the manufacturer app (Fieldpiece Job Link, Testo Smart, etc.) to clear paired devices, then retry.
Connection Drops During a Test
- Low battery is the most common cause. Replace or recharge probe batteries.
- Battery optimization (Android): Go to Settings > Apps > measureQuick > Battery and set to "Unrestricted." Samsung devices: also check Device care > Battery > Background usage limits.
- Range: BLE range varies by probe. If you walk away from indoor probes to check the outdoor unit, use the Hold button to freeze readings before leaving BLE range.
- Too many probes: Some phones struggle with 7+ simultaneous BLE connections. Disconnect tools you are not actively using.
Probe Connected but No Data
- Make sure the probe display shows a live reading (not a sleep or error screen).
- Check channel assignment in Probe Manager. Tap the probe and reassign if needed.
- Update probe firmware via the manufacturer companion app.
- Update measureQuick to the latest version.
Device Compatibility
measureQuick requires:
- iOS: iPhone or iPad running iOS 15.0 or later
- Android: Android 10 or later with Bluetooth Low Energy support
Older devices or budget tablets may lack BLE hardware. If a specific probe model is not compatible with your device, the manufacturer companion app (not measureQuick) determines hardware support.
