- Factored periodic timer funcitonality out of fiber scheduler and into a new SystemTimer module module.
- Enapsulated "ticks" variable within SystemTimer module, with accessor funciton.
- Added accessor/mutator functions to get and set the tick period.
- Added a class wrapper to permit periodic callbacks to both C and C++
functions.
- Updated all references in microbit-dal to use this refactored API.
Previously the range of the servo API was incorrect and would only
translate to a range 0 degrees - 90 degrees in the real world.
This patch updates the #defines used in the servo api default
calculation to calibrate for the intended range of 0 - 180 degrees.
This was all due to working from a specification that applied to a
subset of servos.
Previously, we would rely on service changed to complete successfully
to signify a successful cccd state restore.
However, android doesn’t register for service_changed notifications,
and as a result sd_ble_gatts_service_changed always returns an error.
This meant that cccds would be erased when the complete flag was not
one, which would have been all the time.
Updates to MicroBitButton and MicroBitMultiButton to align the API through
which CLICK events are filtered. Also, updates to the mechanism through which
buttonA and buttonB CLICK/LONG_CLICK events are filtered by
MicroBitMultiButotn to reduce RAM footprint.
No changes to external behaviour of these classes.
This commit introduces a wait_ms before entering DFU mode to allow soft
device to communicate to an android handset that the current connection
should be terminated.
This commit addresses a number of outstanding issues:
* whitelisting behaviour, form the nrf51-sdk, where an address and an
irk were added to the whitelist
* bond management bugs, from the nrf51-sdk, where one device would
replace another.

Re-pairing the same BLE device under SoftDevice 8.0 Nordic SDK 10 appears to
add a second entry to the bonding table when private resolvable addresses are
used by the central device. This adversely affects whitelisting, as only the
first added matching entry will be succesfully added to the whitelist. i.e. A
central device will no longer be able to connect to a micro:bit after pairing
a second time as the older bond will take prescedence.
Althoguh reported to Nordic, a long term fix is not immediately forthcoming.
This patch applies a workaround, by simply reversing the order of the
whitelist before use. As the list is maintained in the order of insertion,
reversing the list guarantees that the entry added to the whitelist will be
the most recently bonded one for any given peer.
Update to MicroBitConfig.h such that the MICROBIT_BLE_OPEN option now also
sets the radio transmission power to its hardware default (0dbm),
rather than the child protection setting (-30dbm).
before resetting
Requests made for an optional timeout function to define the period of time in
which the device will remain in a panic state. This patch introduces a
setErrorTimeout() method with this functionality.
MicroBitMultiButton now provides an indication to MicroBitButton instances when an application is actively utilising that button as part of a button group. This
permits that MicroBitButton to more accurately filter events, and provide a
consistent abstraction.
More specifically, this patch:
- Extends the MessageBus functionality to indicate when listeners are
attached to events. This allows components to perform on demand tailoring
of their behaviour.
- Extends MicroBitMultiButton to indicate to relevant MicroBitButton
instances when they are part of a button group.
- Extends MicroBitButton to perform filtering of button events dynamically
(rather than statically) when part of a MultiButton group.
- Code cleanup of static functions that are more cleanly implemented as
methods.
Updates to MicroBitConfig options and initialisaiton code of the BLE stack to
allow Soft Device's GATT table to be of a given size. If this size is smaller
then the default, the runtime will reclaim that that memory as heap storage.
The nordic implementation of the mbed whitelist API introduces entries into
the table that are not bonds. This patch corrects an assumption in
microbit-dal that the number of entries in the bond table table corellates
with the number of bonds.
The BLE security options mandated for child protection can be highly
detrimental to the development process for new BLE services. This patch
introduces a configuration option to disable BLE security for this purpose.
Default BLE security settings remain unchanged.
Datagram receive code incorrectly calculated the payload length, resulting in
packets being delivered to applications that were two bytes shorter than they
should be.
