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: [elitebook]# info 20:16:B9:D8:A9:3B Device 20:16:B9:D8:A9:3B (public) Name: elitebook Alias: elitebook Class: 0x001c010c Icon: computer Paired: yes Trusted: yes Blocked: no Connected: yes LegacyPairing: no UUID: IrMC Sync (00001104-0000-1000-8000-00805f9b34fb) UUID: OBEX Object Push (00001105-0000-1000-8000-00805f9b34fb) UUID: OBEX File Transfer (00001106-0000-1000-8000-00805f9b34fb) UUID: Headset (00001108-0000-1000-8000-00805f9b34fb) UUID: Audio Source (0000110a-0000-1000-8000-00805f9b34fb) UUID: Audio Sink (0000110b-0000-1000-8000-00805f9b34fb) UUID: A/V Remote Control Target (0000110c-0000-1000-8000-00805f9b34fb) UUID: A/V Remote Control (0000110e-0000-1000-8000-00805f9b34fb) UUID: Headset AG (00001112-0000-1000-8000-00805f9b34fb) UUID: Phonebook Access Server (0000112f-0000-1000-8000-00805f9b34fb) UUID: Message Access Server (00001132-0000-1000-8000-00805f9b34fb) UUID: Message Notification Se..

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?
