Hello,
I am using Bluez 5.32 on kernel 4.1.
When I run advertisement-example, bluez successfully sends
advertisement but then as an answer to scan request it sends an empty
scan response.
Any idea what can be the problem?

Could you please add the trace, iirc BlueZ only set the scan data so
it is up to the controller to generate the scan response not the host
stack so perhaps there is something wrong with your controller.

Hi Luiz,
I tried with 2 BT 4.0 dongles both of which have the same problem. And
instead of running example-advertisement, if I run the following
commands 2 commands manually, it works fine and I can discover and
connect to my device:
hcitool -i hci0 cmd 0x08 0x0008 3 02 01 05
hciconfig hci0 leadv
So I only have problem with the dbus advertising api. Copying the
commands and output from btmon below. example-advertisement does not
seem to set and advertisement data at all.
