v1.1.1 - 02/05/2024

Patch release

Package	Version
Bootloader	v1.0.0
NuttX	v12.2.1

Improvements

In case of repeated latch errors, locks are now ensured to be open before entering the ERROR state. This ensures that the bike cannot be left in a “half-locked” state.
Default latch error retries increased from 5 per 1 min to 50 per 10 mins.
Improved LED behavior during docking debounce and for the “bike removal prompt” in inhibit state.

Fixes

Improvements & fixes in I2C driver to better handle communication errors. Eliminates possible left & right LED state desychronization in some rare cases.
Increased the RFID reset pulse duration to ensure reliable operation of all reader models.

v1.1.0 - 31/10/2023 🎃

Major release

Package	Version
Bootloader	v1.0.0
NuttX	v12.2.1

Improvements

Application manual improvements and additions.
Added the despicable feature. (Ignore this!)
Added lock latch position sensor support (R3.0 & R4.0 only).
Added latch position monitoring while actuators are energized.
Improved initial dock state detection algorithm, taking into account the latch position.
Improved all states error & tamper detection, taking into account the latch position.
Added handling of inadvertently locked latches while in PENDING state.
Added locks and presence monitor debouncing while a bike is being docked.
Added handling of repeated errors.
Improved LED effects in various states.
Improved the default state machine timings configuration.
Improved the default actuator power setting, based on real-life tests.

Fixes

Fixed edge case where a bike may be erroneously allowed docking while in INHIBIT state, after successfully exiting the ERROR state. Such errors are now “fatal”.

Breaking Changes

The Lock x State fields in Bike -> Lock Status messages have been changed to include latch position information. The old, enumerator-based values have now been substituted with a bitfield.

v1.0.3 - 05/10/2023

Patch release

Package	Version
Bootloader	v1.0.0
NuttX	v12.2.1

Improvements

Minor improvements in application manual.
Added F/W image validation while it is being downloaded (only enabled in sim for the moment).
RFID reader is now pre-enabled in PENDING state, significantly improving the read speed when a bike is docked.
Minor improvement in LEDs behavior when entering the INHIBIT state.
Lock mechanisms are re-set to position when entering / exiting the INHIBIT state, ensuring correct lock position.
Lock mechanisms are re-set to position when prompting user to remove bike, to prevent accidental locks.
Improved state checks for setting the API inhibit flag.

Fixes

Fixed state machine, not entering the INHIBIT state when the dock was in LOCKED state.
Fixed bug where the bike was inadvertently unlocked when dock was inhibited, disabled and then re-enabled.
Fixed initial state of RFID reader, where it was erroneously enabled after device boot.
RFID read timeout increased to a more appropriate value for the selected reader.
Charger AC-reset pulse increased to a more appropriate value for the selected charger.

Improvements

Added support for P variant BD176EC boards.

Fixes

None.

Breaking Changes

v1.0.1 - 11/09/2023

Patch release

Package	Version
Bootloader	v1.0.0
NuttX	v12.2.1

Improvements

Additions and improvements in project documentation (application manual).
Added support for BD176EC-R4.0 boards.
Added support for the on-board temperature sensor, including new API command (R4.0 boards only).
Added support for external (AC) charger relay, including new API command (R4.0 boards only).
The wait time of the RELEASE state is now configurable (dock.release_wait).
Lock actuators force is now configurable (dock.lock_pwr).
Lock actuators use increased power when retrying movement after a lock/unlock failure.
Reboot messages can now be broadcasted and do not require encryption.

Fixes

Enabled & inhibit status flags are set according to both the parameters value and the actual state of the dock.
Fixed fatal error status flag, not being set when error handling fails (system blocked in ERROR state).
Exit from DISABLED state is no longer allowed, in case of any fatal error.
Fix in charger error handling, not respecting the correct timings of the procedure.
Bug fix in CRC16 algorithm, not using all bytes in the provided buffer in specific cases.

Breaking Changes

Due to the fix in CRC16 algorithm, some systems may face checksum errors.
