Bluetooth for RISC OS
=====================

Plays sound through Bluetooth speakers and headphones (A2DP), and works
with Bluetooth mice and keyboards (classic and Low Energy), through a
USB Bluetooth adapter. Tested with a TP-Link UB400 (CSR8510) on a
Raspberry Pi CM4 under RISC OS 5.

Icon bar
  SELECT   open the Devices window
  MENU     status, Info, Devices, connect the saved speaker,
           Disconnect all, Configure, Quit
  ADJUST   open Configure > Bluetooth

Devices window
  Scan       look for devices for 10 seconds; put the device in
             pairing mode first
  Connect    pair with the chosen device and connect it
  Disconnect drop the chosen device's connection
  Forget     remove the pairing; the device must be paired again

Paired devices come back by themselves: when the computer starts, and
whenever a sleeping mouse or keyboard wakes. A speaker that was off is
picked up within a few minutes of being switched on, or click Connect.

Problems are shown in the Devices window's status line, never in a box
that would stop the desktop.

The drivers (BluetoothVoice and the USB driver) are loaded before the
desktop starts, from Choices:Boot.PreDesk.Bluetooth. Use !Install to
add or remove everything.

Settings and pairings are kept in Choices:Bluetooth.
