Jim Mussared 919d640aec extmod/modbluetooth: Allow discovery of svc/char by uuid.
In most situations this is a more efficient way of going straight to the
service and characteristic you need.

Jim Mussared 6a3c89d584 extmod/modbluetooth: Add discover complete events for svc/char/desc.
Without this it's difficult to implement a state machine correctly if the
desired services are not found.

Damien George 3b6c9119eb extmod/modbluetooth: Add support for changing the GAP device name.
This commit allows the user to set/get the GAP device name used by service
0x1800, characteristic 0x2a00.  The usage is:

    BLE.config(gap_name="myname")
    print(BLE.config("gap_name"))

As part of this change the compile-time setting
MICROPY_PY_BLUETOOTH_DEFAULT_NAME is renamed to
MICROPY_PY_BLUETOOTH_DEFAULT_GAP_NAME to emphasise its link to GAP and this
new "gap_name" config value.  And the default value of this for the NimBLE
bindings is changed from "PYBD" to "MPY NIMBLE" to be more generic.

Jim Mussared c987adb9e9 extmod/btstack: Implement more robust init/deinit sequencing. 2020-04-29 16:45:46 +10:00
Jim Mussared 8119ec0765 extmod/modbluetooth: Don't hold atomic section during mp_sched_schedule.
Because, for example, on unix the atomic section isn't re-entrant, and
mp_sched_schedule() will try to re-acquire the atomic section.

Damien George 899e89d4c6 extmod/btstack: Pass through SCAN_RSP events.
The latest version of BTstack has a bug fixed so that it correctly
configures scan parameters if they are set right after activating the
stack.  This means that BLE.gap_scan() will correctly set the scanning to
passive and so SCAN_RSP events are not passed through, so we don't need to
explicitly filter them in our bindings.

Damien George dd0bc26e65 extmod/modbluetooth: Change scan result's "connectable" to "adv_type".
This commit changes the BLE _IRQ_SCAN_RESULT data from:

    addr_type, addr, connectable, rssi, adv_data

to:

    addr_type, addr, adv_type, rssi, adv_data

This allows _IRQ_SCAN_RESULT to handle all scan result types (not just
connectable and non-connectable passive scans), and to distinguish between
them using adv_type which is an integer taking values 0x00-0x04 per the BT
specification.

This is a breaking change to the API, albeit a very minor one: the existing
connectable value was a boolean and True now becomes 0x00, False becomes
0x02.

Documentation is updated and a test added.

Fixes #5738.

Jim Mussared 1937fb22ab extmod/nimble: Clarify active state and check for active in all methods.
This commit ensures that the BLE stack is active before allowing operations
that may otherwise crash if it's not active.  It also clarifies the state
better (adding the "stopping" state) and renames mp_bluetooth_is_enabled to
the more self-explanatory mp_bluetooth_is_active.
