  Hi, 

  I recently bought a new phone: OnePlus 13 and I'm trying to pair with my Aranet4 device. I press "Add a new device" and nothing happens. I get a spinning wheel for a couple of seconds and it says "Loading..."

  My first thought was that it was my previous pairing that was interfering with pairing with my new phone so I forgot that device and uninstalled the app on the old phone. I've also cleared the cache and reinstalled the app multiple times now. No luck. It's quite an expensive device, so it's important to me to get this working. Any help to be had?

  Please try these steps in order:
  
  •             Take out the batteries of your Aranet4 device for 15 minutes.

  •             Make sure the Bluetooth switch at the back of the Aranet4 is ON.

  •             Uninstall the Aranet4 app on the phone.

  •             Delete Aranet4 from the Bluetooth-paired list on your phone.

  •             Restart your phone.

  •             Install the Aranet4 app from the Google Play store.

  •             Connect the Aranet4 sensor to your phone using the Aranet4 app; you should be prompted for a 6-digit PIN code presented on the sensor screen.

  
  If this doesn’t work, clearing your phone's Bluetooth cache might.

  I've tried all these steps. It doesn't work.

  I can also confirm that it works on my old phone still: Google Pixel 6. Therefore it's not a problem with the unit. 

  Is there a known compatibility issue with OnePlus 13?

  We have not had any OnePlus 13 compatibility issues reported, but we cannot verify compatibility with every brand and model.

  Searching the Web it is apparent that various OnePlus 13 users report Bluetooth connectivity and stability issues, and as possible temporary solutions, the following is mentioned:

  • Enabling Developer Options and changing the Bluetooth AVRCP version to 1.3.

  • Clearing the Bluetooth cache: Settings > Apps > Bluetooth > Storage > Clear Cache.​

  • Resetting network settings: Settings > System > Reset options > Reset Wi-Fi, mobile & Bluetooth.​

  • Ensuring the device is updated to the latest firmware.​

  Additionally, you can use Bluetooth debugging software (e.g., nRF Connect from the Google Play Store) to see if the Aranet4 is discoverable and analyse the connection process. Pairing can be initiated in nRF Connect via “Secure DFU Service --> Buttonless DFU”. The device will appear as “BONDED” when successfully paired.
