Wireless Sensor Won't Connect or Not Available on Android Device

I am running SPARKvue for the first time on my Android device and the software cannot find my sensor.

Running SPARKvue for the first time on Android, the software asks for permission to use location services.  This is required for BLE, due to the proximity feature. 

Requirements to connect PASCO Wireless Sensors to Android OS:

The following must be enabled in the Android System Settings menu to pair to Wireless Sensors:

• Bluetooth
  Location Services (always on)*
  You must also have the free SPARKvue or MatchGraph App from the Google Play store
  • *Location Services is required for the full Bluetooth identification and pairing on Android. It must be set to "always on" to use the Wireless line of sensors. Location data is not transmitted to PASCO or any third-parties.
• Note: SPARKvue is only supported on native Android OS. We do not support any Android OS variants such as EMUI or Oxygen OS.

Different Android Models seem to be, behaving differently in these instances.

In Android 9, granting permission allows sensors to be detected right away. 

In Android 10, SPARKvue must be restarted before sensors can be seen.

In Android 12, the permission requested is ‘approximate’ location on first run.  If this is given, SPARKvue must be restarted at which point ‘precise’ location permissions will be requested.  Only after this the precise permission is given will sensors show in the connection dialog.

If the above do not get your wireless sensor connected to your Android device, please uninstall SPARKvue and reinstall.  Please pay close attention to any notifications that are presented to you when you are reinstalling. 

You may also need to clear the SPARKvue app data:

• Tap on the “Settings” icon on your device to get to all of the settings options.
• In Settings, scroll down the left side and tap on “Apps.” Then in the list of apps, scroll down to SPARKvue and tap on the listing to see the settings for SPARKvue.
• In the SPARKvue settings, first tap on “Force Stop” found at the top of the page.  This assures that SPARKvue is not running in the background.
• Next, tap on the “Storage” section.  You will now see two options to “Clear Data”, and “Clear Cache”.  Tap on both of these selections.  This deletes and stored data.
