Package: Bluez Version: 5.48
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 start ----------------------------------------- #: ../bluez-5.48/src/adapter.c:adapter_service_add() /org/bluez/hci0 #:

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.
