That seems all correct for now. Test example-gatt-server registers
Heart Rate, Battery & Test services. All of them appeared as expected.
My problem is that I can't list GATT attributes. I don't any output.
Is there anything I'm doing incorrectly?
I decided to test nRF Connect Android app. It showed something
interesting about my bluetooth devices. It nicely displays & parses
advertising data.
Logitech M590 advertises:
0x01 Flags
0x03 Complete List of 16-bit Service Class UUIDs
0x09 Complete Local Name
0x0A Tx Power Level
0x19 Appearance
BlueZ on "elitebook" advertises:
0xFF Manufacturer Specific Data
or to say precisely:
0x1BFF750042040180AE78BDBC0B7E307ABDBC0B7E2F01000000000000
Any idea/hint why BlueZ 5.30 on my "elitebook" notebook doesn't
advertise more data?
I've discovered I also need to run test/example-advertisement. Then I
can see my notebook advertise UUIDs and characteristics. It seems that
test/example-gatt-server is insufficient on its own.
