bluez version on netPi
#2
Hi Armin,

I started with the netpi-raspbian image. I shared the file /var/run/dbus/system_bus_socket and use the host network in the container and started the container in privileged mode so I can connect to the bluetoothd running on the host via dbus.
Then I built the bluez-5.41 from source to match the bluez version with the one of bluetoothd running on the host.
> cd bluez_source_dir
> ./configure
> ./make

There should be a file called bluez_sorce_dir/client/bluetoothctl which also uses the bluez dbus-API as I want to used from my own application. You have to start it as root.

After powering on the bluetooth adapter
> [bluetooth]# power on
scanning for bluetooth devices
> [bluetooth]# scan on
> [NEW] Device B0:91:22:68:27:01 Name: XXX
and connecting to a bluetooth device
> [bluetooth]# connect B0:91:22:68:27:01
there should appear a list of GATT characteristics depending on the bluetooth device.

Something like this:
[CHG] Device 5C:31:3E:71:0C:E7 UUIDs: 00001800-0000-1000-8000-00805f9b34fb

...

You can test with a fitness-tracker or another bluetooth peripheral using GATT. Or you could use an android phone. To start a GATT server and start advertising you can use the nRF Connect for Mobile app.

With bluez-5.41 the GATT-DBUS API is still experimental and the Characteristics are not discovered because you have to compile and run the bluetoothd with experimental features enabled. I expect it to work with bluez version >= 5.43 since this feature is no longer experimental from this point. I would prefer version 5.47 because the release notes state some fixes for GATT until there.

Thomas
