Bluetooth¶
Use bluetoothctl to enable bluetooth and scanning:
$ sudo bluetoothctl
[bluetooth]# agent on
Agent is already registered
[bluetooth]# default-agent
Default agent request successful
[bluetooth]# scan on
Discovery started
Press the Bluetooth button on SPIKE, in bluetoothctl you should see something like:
[NEW] Device 40:BD:32:46:9D:3F 40-BD-32-46-9D-3F

[CHG] Device 40:BD:32:46:9D:3F Alias: LEGO Hub@dwalton76-hub
Now pair with that device:
[bluetooth]# pair 40:BD:32:46:9D:3F
