Hi,
I have 2 notebooks with Bluetooth running bluez 5.30. I called them:
1) "elitebook" with controller 20:16:B9:D8:A9:3B
2) "matebook" with controller 38:BA:F8:3F:7C:A7
Normally, when I check elitebook from matebook I get this:

I decided to test GATT. On elitebook I started:
./test/example-gatt-server
and waited to let matebook refresh all info.
After that I got:

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 guess what you are looking for is list-attributes local though that
only works for service register by bluetoothctl itself not by other
applications, those objects are normally accessible to bluetoothd only
and we don't expose objects from other application.

I'm confused now. I thought I understand the purpose of "menu gatt" +
"list-attributes". I'm not BlueZ expert but it seems to me to be well
capable of accessing GATT of remote devices.
When I connect my Logitech M590 BLE mouse I can use "menu gatt" +
"list-attributes" to access its GATT.
Why accessing GATT of another notebook would be any different? I'm not
sure what I'm missing.
There is an example of me using "bluetoothctl" to access GATT of M590:

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?

Just to be sure, are you using 5.30? If so, update to 5.50..

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.

Yeap, gatt-server is only for GATT. And advertisement has spearate API as
those are not necesserily used together.
