Device Management Client Lite 1.4.0

Example application

• Fixed a bug that caused the application to assume event_id and event_type are both 0 when the event handler is initialized. Now, it uses PDMC_CONNECT_STARTUP_EVENT_TYPE -1 from Client's LWM2M interface when creating the event handler.
• [Mbed OS] Updated ISM43362 Wi-Fi driver to #3813a4b with fixes for logging and UDP socket handling.
• Bootloader changes:
  • Changed the bootloader library name from tools.lib to prebuilt-bl.lib.
  • The new bootloader library contains a bootloader binary image and an mbed_lib.json file for each target in the prebuilt-bl/TARGET_target_name/TARGET_BL_INTERNAL_FLASH directory. The mbed_lib.json file defines common configurations for the bootloader and the application, including the bootloader flash bank size; the storage type, address and size; firmware-over-the-air (FOTA) storage configurations; header_format; and restricted_size.
  • Added the target.bootloader_img parameter to the mbed_lib.json file of the bootloader. This parameter defines the path to the bootloader image.
  • Set the storage configuration to null in the mbed_app.json file to ignore the default storage configuration. As a result, the build system uses the configuration defined by the mbed_lib.json file of the bootloader.
• [Mbed OS] Updated to 6.12.0:
  • minimal-printf is now enabled by default. You can disable it by adding "target.printf_lib": "std" to the application configuration. For example, using float type LWM2M resources requires disabling minimal-printf.

Device Management Client Lite 1.2.0

Updated applications and bootloaders to support manifest version 3. This enables support for FOTA library features:

• Update download resume (currently not supported for differential updates) - resume download in case power or connectivity loss.
• Support firmware candidate encryption (useful for external storage) - disabled by default.
• Component update - allow an application to register custom components and installers.
• Semantic version - firmware version is reported based on the semantic version format.
• Firmware version is reported on the /14/0/2 resource.
• Manifest tool v2.0.0 is required to work with this FOTA library.
• Update x.509 certificate is replaced with a public key in uncompressed point format (X9.62) - requires less memory.
• An application can defer the update.

Device Management Client Lite 1.1.1

Increased the default lifetime of UDP_QUEUE mode devices to 600 seconds. The earlier, shorter lifetime was causing intermittent issues where the device was unable to re-register before the lifetime expired.

• Workaround for GCC LTO issue #12871 in Mbed OS 6.0.0 Alpha 3 to pico_lte_size.json.

• Added support for delta-tool and delta updates.

• Added new configuration mbed_app_baremetal_tls.json for K64F and ESP8266 Wi-Fi to compile for baremetal optimized Mbed TLS configuration:

  1. In the mbed-cloud-client/tools folder, run ./setup_optimized_mbedtls.sh.
  2. To compile, run:

  mbed compile -m K64F -t GCC_ARM --app-config mbed_app_baremetal_tls.json --profile profiles/pico_lte_size.json --profile mbed-os/tools/profiles/extensions/minimal-printf.json
