FOTA over Bluetooth Low Energy using the nRF5340 DK

[sasikumar p]

  We are currently working through Exercise 5 – FOTA over Bluetooth Low Energy using the nRF5340 DK  and encountering an issue where the mobile application (nRF Connect for Mobile) displays a “Device not supported” message upon connecting to the board.

Details:
Device Name: Nordic_LBS
Exercise  Used :  I9/I9_e5sol
Bluetooth Address: C7:01:13:DD:1E:93
App Used: nRF Connect for Mobile (Android)
nRF5340 DK Terminal Output: The board repeatedly connects and disconnects (0x13 error), which causes it to restart advertising.

Attachments:
Screenshot of the nRF Connect app with error
Terminal output from the nRF5340 DK (via serial terminal)

Could you please advise on what might be causing the “Device not supported” issue and how it can be resolved?

Hello,

This issue could be related to the SDK version you are using. Are you building the application using Sysbuild?

To ensure you're using the correct sample from the repository, could you please confirm which branch you're selecting for l9/l9_e5sol? Please refer to the screenshot below. Note that the main branch only works with NCS v3.0.0 and above.

Regarding the configuration, I believe what you're looking for is CONFIG_MCUMGR_TRANSPORT_BT, which is enabled by setting CONFIG_NCS_SAMPLE_MCUMGR_BT_OTA_DFU.

Kind Regards,

Abhijith

Hello,

Thank you for your previous response.

I’m currently working with the nRF5340 DK and SDK version v2.6.4, and I would like to enable FOTA (DFU over BLE) in this version.  

Could you please guide me on the correct steps or configurations required to implement FOTA using MCUmgr over BLE with SDK v2.6.4?

Any information about necessary configurations (prj.conf), overlays, partition settings, or compatible samples would be greatly appreciated.

Best regards,
Sasi
