Device Management Client 2.1.0 General Availability (GA)
- Edge-specific unregistration parameter
dfor a translated device to the registration message body.
- Yocto Sumo support.
Device Management Client example
Updated to Mbed OS 5.10.3.
Device Management Connect client
Start reconnection if no response received for CoAP ping.
Factory configurator client
Fixed SOTP flash write area to accept values larger than eight bytes.
Device Management Update client
- Implemented new error codes for the campaign metrics feature.
- Client reports an error if the firmware image is greater than the device flash limit.
- Fixed issues with 32-bit addressing limits to enable downloading of very large firmware images.
- Removed an unnecessary DNS lookup. The HTTP source FSM implementation repeated the DNS lookup on every new fragment, even though in most cases the data was expected to be in the TCP receive buffer already. This modifies the FSM to avoid that step unless it is necessary.
- Added logic to generate a compilation error for an invalid download protocol value.
- Defined additional, individually enabled trace functions at compile time to reduce the resume trace ROM size.
- Fixed various Linux warnings.
- Replaced incorrect licence headers for Apache 2.0 and added license headers where missing.
- Removed dependency to the deprecated component
COMMON_PALthat was removed in Mbed OS 5.9.
ARM_UC_cryptoDecryptagainst unnecessary calls.
- Removed external reference to
arm_uc_blockdeviceand used the default block device instance from Mbed OS instead.
- Added debug messages to check the frequency of resume attempts.
Platform Adaptation Layer (PAL)
- Refactored the internal library structure to allow more streamlined porting to new platforms.
- Removed the limitation for setting the page size for SOTP.
We recommend searching the issue list in the Mbed OS repository for known issues and their latest status.
- For flashing the
.hexbinary with Mbed OS 5.10, you must update your board's DAPLINK firmware to version
- Client does not handle packet duplication correctly, which can result in Client being unable to connect. This is fixed in Mbed CoAP 4.7.2, which will be part of Mbed OS 5.11.0 release.
- Firmware update from one Linux distribution version to another does not work. For example, firmware update from Yocto distribution Morty to Rocko is not currently possible, as there are Linux version-dependent files (device tree) in the
BOOTpartition. Therefore, updates need to be done within one major version of a distribution.
glibcversions 2.23 and 2.24 have a bug in thread creation. It can cause random crashes with Linux.
- If possible, update
glibcto version 2.25 (or newer). See sourceware issue 20116 for details.
- We have implemented a workaround for this issue to decrease its likelihood. This issue may still occur under certain circumstances.
- If possible, update
- The Device Management Client application must run as
rootto have access rights to perform the firmware update.
- This is not the most secure way to handle this issue, so a more secure implementation will come later.
- Yocto distribution has only been tested in the developer certificate mode.
