Bluetooth Advertising Interruption Issue with BlueZ Versions Above 5.55 on nRF52833

[Doris.chen]

We are currently using a Linux system and controlling HCI_UART firmware through BlueZ.

The problem we are encountering is that using BlueZ V5.55 allows normal Bluetooth advertising and connection with mobile phones. However, when using higher versions like 5.64 and 5.66, we experience interruptions in advertising.

Has anyone encountered similar issues? Do we need to adopt a higher version of NCS?

Or is there any modification needed in the firmware? Currently, we are using the original code provided by NCS.

Current information is as follows:

Board: nRF52833

NCS version: V2.5.0

Hi, 

It is worth trying to update your NCS version if there are any specific compatibility issues between the BlueZ version and the NCS version you are using. The latest NCS is v2.7.0.
