I am writing an application which communicates to Bluez over dbus APIs. I have a wilink 8 bluetooth 4.2 Low energy chip on my board.

I am using example-advertisement and exmaple-gatt-server from test folder of the project as a reference to write my applicaiton.

When I perfrom RegisterApplicaiton followed by RegisterAdvertisemtn then I can see that the bluez service is crashing.

Please find below bluez logs. I dint not find any error or timeout in btmon.

----------- Bluez logs end -----------------------------------------


My application is really simple whcih registers one service and characterisits and the required LE properties. I dont see any error in dbus communication.

I dont understand the reason for bluez crash. Please help me out.

I would like to know what I am doing in wrong in my applicaiton. My application uses sd-bus library.

Any comments would also be helpful. I am ready to share if any further information is required.

Thanks for the support.
