    Ensure airplane mode is toggled off.

  • Make sure Discovery is enabled: Settings > Connectivity > Discovery.

Verify on your phone:

  • Ensure you have the latest app version installed. Go to Play Store (Myapp or other) and check for available app updates.
  • Check if Bluetooth is activated on your mobile phone.


Troubleshooting steps:

Verify after every step if the connection issue was resolved. If not proceed with the subsequent tips:

  1. Restart your mobile device.
  2. Reset the Bluetooth connection: Turn your phone’s Bluetooth off, wait for a few seconds and activate it again.
