Damien George 7bf62562ce extmod/nimble: When getting BLE MAC try public address if random fails.
This is needed for BLE.config('mac') to work on esp32.

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.

Damien George e965363b6b stm32: Refactor Bluetooth HCI RX to be independent of transport layer.
Now all HCI specific code (eg UART vs WB55 internal messaging) is confined
to modbluetooth_hci.c.

Damien George 0ac06a510a extmod/modbluetooth: Extract out gatts_db functionality from nimble.
For use by other stacks, if they need it.

Work done in collaboration with Jim Mussared aka @jimmo.

Damien George 894c550c86 stm32: Refactor bluetooth stack/hci/driver bindings.
This makes a cleaner separation between the: driver, HCI UART and BT stack.
Also updated the naming to be more consistent (mp_bluetooth_hci_*).

Work done in collaboration with Jim Mussared aka @jimmo.

Damien George c44d52f33e extmod/modbluetooth_nimble: Move nimble specific code, factor nimble.mk.
Move extmod/modbluetooth_nimble.* to extmod/nimble.  And move common
Makefile lines to extmod/nimble/nimble.mk (which was previously only used
by stm32).  This allows (upcoming) btstack to follow a similar structure.

Work done in collaboration with Jim Mussared aka @jimmo.

Damien George 78145b98ef extmod/nimble: Remove unneeded nimble_sprintf wrapper function. 2019-11-01 12:15:07 +11:00
Jim Mussared 418f12c5f5 extmod/modbluetooth: Increase maximum connections from 1 to 4.
This avoids a confusing ENOMEM raised from gap_advertise if there is
currently an active connection.  This refers to the static connection
buffer pre-allocated by Nimble (nothing to do with MicroPython heap
memory).

Jim Mussared 902bb4ceae stm32: Extract port-specific Nimble implementation.
On other ports (e.g. ESP32) they provide a complete Nimble implementation
(i.e. we don't need to use the code in extmod/nimble). This change
extracts out the bits that we don't need to use in other ports:
 - malloc/free/realloc for Nimble memory.
 - pendsv poll handler
 - depowering the cywbt

Also cleans up the root pointer management.
