Segmentation Fault in BLE Heart Rate Game example adaptation code.

DukeReddy

Hi all,

I am currently working on a BLE Central device. I adapted the project from one of the examples (Heart Rate Game).
The modifications I did to this project are:

Removed QML (Only CLI interface is present)
On finishing the communication between the central-peripheral the BLE service is closed.

The segementation fault occurs when I close/shutdown the BLE service.
Qt version: 6.2.3, qthread_p.h, Line 310.

I am not sure why there is a segmentation fault. Could anyone please help me or point me to look in the right direction of figuring out the issue?

Best regards,
Navin
