`bluetooth`

Bluetooth, from BlueZ, followed live: the first adapter, the devices paired with it, and the devices in range while a pairing page reads them.

Field	Type
`powered`	`bool rw`	The adapter is on. Writable.
`devices`	`[BluetoothDevice]`	Paired devices, keyed by `address`.
`available`	`bool`	BlueZ answers and has an adapter: false without them (or without a system bus), so a menu can hide what cannot work.
`nearby`	`[BluetoothDevice]`	Unpaired devices in range that have a name, keyed by `address`, found by discovery. Discovery runs only while a visible reader reads them (a pairing page that is open).
`scanning`	`bool`	The adapter is discovering devices, for `nearby` or for another program.

Event
`on bluetooth.failed(address: text, error: text)`	Connecting, disconnecting, pairing or forgetting a device failed (out of range, turned off, timed out, or the service not running): `on bluetooth.failed(address, error) { … }`.
