"""
Low-level Bluetooth radio functionality.
MicroPython module: https://docs.micropython.org/en/v1.21.0/library/bluetooth.html
This module provides an interface to a Bluetooth controller on a board.
Currently this supports Bluetooth Low Energy (BLE) in Central, Peripheral,
Broadcaster, and Observer roles, as well as GATT Server and Client and L2CAP
connection-oriented-channels. A device may operate in multiple roles
concurrently. Pairing (and bonding) is supported on some ports.
This API is intended to match the low-level Bluetooth protocol and provide
building-blocks for higher-level abstractions such as specific device types.
``Note:`` For most applications, we recommend using the higher-level
`aioble library <https://github.com/micropython/micropython-lib/tree/master/micropython/bluetooth/aioble>`_.
``Note:`` This module is still under development and its classes, functions,
methods and constants are subject to change.

Each **characteristic** is a two-or-three-element tuple containing a UUID, a
**flags** value, and optionally a list of *descriptors*.
Each **descriptor** is a two-element tuple containing a UUID and a **flags**
value.
The **flags** are a bitwise-OR combination of the flags defined below. These
set both the behaviour of the characteristic (or descriptor) as well as the
security and privacy requirements.
The return value is a list (one element per service) of tuples (each element
is a value handle). Characteristics and descriptor handles are flattened
into the same tuple, in the order that they are defined.
The following example registers two services (Heart Rate, and Nordic UART)::

def irq(self, handler, /) -> int:
"""
Registers a callback for events from the BLE stack. The *handler* takes two
arguments, ``event`` (which will be one of the codes below) and ``data``
(which is an event-specific tuple of values).
**Note:** As an optimisation to prevent unnecessary allocations, the ``addr``,
``adv_data``, ``char_data``, ``notify_data``, and ``uuid`` entries in the
tuples are read-only memoryview instances pointing to :mod:`bluetooth`'s internal
ringbuffer, and are only valid during the invocation of the IRQ handler
function. If your program needs to save one of these values to access after
the IRQ handler has returned (e.g. by saving it in a class instance or global
variable), then it needs to take a copy of the data, either by using ``bytes()``
or ``bluetooth.UUID()``, like this::
connected_addr = bytes(addr) # equivalently: adv_data, char_data, or notify_data
matched_uuid = bluetooth.UUID(uuid)
For example, the IRQ handler for a scan result might inspect the ``adv_data``
to decide if it's the correct device, and only then copy the address data to be
used elsewhere in the program. And to print data from within the IRQ handler,
``print(bytes(addr))`` will be needed.

def config(self, param, /) -> Tuple:
"""
Get or set configuration values of the BLE interface. To get a value the
parameter name should be quoted as a string, and just one parameter is
queried at a time. To set values use the keyword syntax, and one or more
parameter can be set at a time.
Currently supported values are:
- ``'mac'``: The current address in use, depending on the current address mode.
This returns a tuple of ``(addr_type, addr)``.
See :meth:`gatts_write <BLE.gatts_write>` for details about address type.
This may only be queried while the interface is currently active.
- ``'addr_mode'``: Sets the address mode. Values can be:
* 0x00 - PUBLIC - Use the controller's public address.
* 0x01 - RANDOM - Use a generated static address.
* 0x02 - RPA - Use resolvable private addresses.
* 0x03 - NRPA - Use non-resolvable private addresses.
By default the interface mode will use a PUBLIC address if available, otherwise
it will use a RANDOM address.
- ``'gap_name'``: Get/set the GAP device name used by service 0x1800,
characteristic 0x2a00. This can be set at any time and changed multiple
times.
- ``'rxbuf'``: Get/set the size in bytes of the internal buffer used to store
incoming events. This buffer is global to the entire BLE driver and so
handles incoming data for all events, including all characteristics.
Increasing this allows better handling of bursty incoming data (for
example scan results) and the ability to receive larger characteristic values.
- ``'mtu'``: Get/set the MTU that will be used during a ATT MTU exchange. The
resulting MTU will be the minimum of this and the remote device's MTU.
ATT MTU exchange will not happen automatically (unless the remote device initiates
it), and must be manually initiated with
:meth:`gattc_exchange_mtu<BLE.gattc_exchange_mtu>`.
Use the ``_IRQ_MTU_EXCHANGED`` event to discover the MTU for a given connection.
- ``'bond'``: Sets whether bonding will be enabled during pairing. When
enabled, pairing requests will set the "bond" flag and the keys will be stored
by both devices.
- ``'mitm'``: Sets whether MITM-protection is required for pairing.
- ``'io'``: Sets the I/O capabilities of this device.
Available options are::
_IO_CAPABILITY_DISPLAY_ONLY = const(0)
