(minimumv1.6
) - bluez bluetooth
v5.48
(minimum supportedv5.43
) - ubuntu 16.04 and raspbian (armv7)
Bluez, the linux bluetooth implementation, has introduced GATT support from v5.43
Ensure you are using an up to date version with bluetoothd -v
See in scripts/
how to upgrade bluez
-
Give access to
hciconfig
to any user (may have security implications)sudo setcap 'cap_net_raw,cap_net_admin+eip' `which hciconfig`
-
Create a dbus profile
ln -s `pwd`/scripts/dbus-dev.conf /etc/dbus1/system.d/go-bluetooth.config
-
Monitor activity
sudo dbus-monitor --system "type=error"
-
View
bluetoothd
debug messagessudo bluetoothd -Edn P hostname
-
Enable LE advertisement (to use a single pc, you will need 2 bluetooth adapter)
sudo btmgmt -i 0 power off sudo btmgmt -i 0 name "my go app" sudo btmgmt -i 0 le on sudo btmgmt -i 0 connectable on sudo btmgmt -i 0 advertising on sudo btmgmt -i 0 power on
- Add docs with examples
- Add Device read / write and custom data converters
- Unit tests coverage
- Integrate hci communication from
