Zephyr

Features

Bluetooth

Support for the Central Address Resolution characteristic was added.

Continuous Integration

Sanitycheck footprint data for the v1.13.0 release was added.

Cryptography

The crypto tests were converted to use config-tls- generic.h, an mbedTLS configuration file that is part of Zephyr which is configurable with Kconfig.

Bugs

Documentation

The release’s documentation was finalized.

Drivers

A fix was merged for ADC on SAM E70.

External

mbedTLS was updated to version 2.12.0 from 2.9.0. This includes various security fixes and functional improvements. These come at the cost of increased resource requirements.

Kernel

Various attempts to support interrupts when CONFIG_MULTITHREADING=n were postponed until after v1.13.0, resolving some observed scheduler issues.

Libraries

A couple of fixes were made to Zephyr’s CMSIS RTOS v1 support shim.

Miscellaneous

A C++-related warning fix was merged to the stack checking feature.

Samples

The latest mbedTLS increased resource requirements; the drivers/crypto sample was adjusted. The main stack size was increased to a rather large 4096 B; the minimum target RAM required to run the sample increased from 16 KB to 20 KB.

Testing

Various final adjustments and fixes were made to the tests to get to release readiness.

hawkBit and MQTT sample application

Features

Helper script improvements

The helper hawkbit.py script now supports Python 3, has “rollout” parameters for controlling a hawkBit-based firmware update to multiple devices, was updated for compatibility with the latest hawkBit release, and has improved help text.

Bugs

Helper script fixes

The help text for the hawkbit.py script was fixed, along with internal fixes for control of hawkBit’s REST API.

LWM2M sample application

Features

Helper script improvements

The helper script now uses mgmt.foundries.io as the default host, supports multithreading with a –threads option, device type filtering with a –device option, logs with the standard logging module, updating of all connected clients, and has quieter output.

Bugs

Helper script fixes

Numerous fixes for error handling were merged to the leshan.py helper script.
