Unable to advertise Bluetooth BLE in peripheral mode in OS Ubuntu 18

[ankursaxena]

Hi All,

My aim is to create Bluetooth BLE Peripheral who would be able to advertise the device and services. For achieving this, I have tried to run the heartrateserver example provided by QT Creator.

I simply run this program and i got following error in the output:

host mode: QBluetoothLocalDevice::HostConnectable
qt.bluetooth: Using BlueZ kernel ATT interface
