BLEGATT API not working properly in 55UR80006LJ model

Web App Development
1

Hi;

I’m developing a web app where I want to use BLEGATT APIs. I’m testing on a TV with webOS24:

  • model: 55UR80006LJ
  • sdkVersion : 9.2.1
  • firmwareVersion : 23.21.30

The BLEGATT API seems not working properly, with getState, pairedDevices and connectedDevices arrays are always empty, even if I have paired devices.
Also the nearby devices permission is always showing when I start the app, sometimes with a wrong application name.
I tried to use the BLEGATT sample app: BLEGATT sample but the application opens and closes immediately.

Are those known issues in that model. if not, could you please share more information about the BLEGATT implementation and how I can have consistent permission while the application is installed.

Thank you in advance.
Best regards.

To use the BLE GATT API, your app should acquire user permission. For more information, please refer to BLE GATT Description. Thank you.

Hi @narae0.kim, I tried thet BLEGATT sample but it open and close immediately.

Please check the permission. Add/delete permissions can be changed in the nearby devices menu in the Settings app. Thank you.

If the BLE GATT API is not working properly on the 55UR80006LJ model, there could be several factors causing the issue. Here are a few troubleshooting steps to consider:

  1. Check API Compatibility – Verify whether the BLE GATT API is fully supported on the 55UR80006LJ model. Some devices may have limited or restricted Bluetooth capabilities. Reviewing the official documentation or contacting the manufacturer may provide clarity.
  2. Firmware & Software Updates – Ensure that the device is running the latest firmware version. Manufacturers often release updates that fix Bluetooth-related bugs and improve API functionality.
  3. Test with Other Devices – Try connecting to different BLE peripherals to determine if the issue is device-specific or a broader API problem.
  4. Inspect Logs & Debug Output – If possible, check system logs or debug output for any error messages related to Bluetooth connectivity or GATT operations. This may provide insight into the failure points.
  5. Confirm Proper Permissions & Settings – Some APIs require specific permissions or settings to function correctly. Ensure that all necessary Bluetooth permissions are granted and that the device is configured to allow BLE connections.
  6. Check for Known Issues – Look through the manufacturer’s forums or support pages to see if other users have reported similar issues and if there are any recommended fixes.
