§Management
For managing the Bluetooth controllers on your device (pairing, discovery,
broadcasting, etc.), you can use the management API. This is contained
inside of the management module, where the central type is
management::ManagementStream.
§Communication
For communicating with other bluetooth devices, you have a couple of
options. You can use L2CAP streams or RFCOMM streams, both of which are
exposed through BluetoothStream.
This library also contains an implementation of Service Discovery Protocol
(SDP) which operates over L2CAP and is availabile in the
communication::discovery module.
§Permissions
Commands that just query information, such as
get_controller_info,
will usually work. However, commands that try to change any settings, such
as
set_powered
will fail with ‘permission denied’ errors if your process does not have the
CAP_NET_ADMIN capability.
