Device Management Client Lite

  • Fixed bug where client assumed that event_id and event_type are both 0 when event handler is initialized. Added definition PDMC_CONNECT_STARTUP_EVENT_TYPE -1 to LWM2M interface. Client uses it initializes connection event handler.
  • Removed the need_reboot = false option in the fota_component_add() API. When registering a component, the need_reboot option must always be true.
  • Updated to support Mbed OS 6.8.0. Baremetal Mbed TLS is now only supported with Mbed OS version 6.8.0 and later.
  • The new Connection ID (CID) feature eliminates unnecessary DTLS handshake traffic between the client and the cloud during reconnection. To have the client persist the CID during reboot, the application can call the pause() API before shutting down the application. This call stores the CID context in persistent memory for use after reboot. The client then uses the CID to establish a secure connection to the cloud without requiring a DTLS handshake. The PROTOMAN_USE_SSL_SESSION_RESUME feature flag, which controls this feature, is enabled by default for Mbed OS and disabled by default for other platforms.
    • Added a compile-time check to require the mandatory Mbed TLS flags are defined when the Connection ID feature (PROTOMAN_USE_SSL_SESSION_RESUME) is enabled.
  • Fixed FOTA full resume.
  • Changes to implementation of update candidate image encryption:
    • Added new FOTA_USE_ENCRYPTED_ONE_TIME_FW_KEY option to MBED_CLOUD_CLIENT_FOTA_KEY_ENCRYPTION.
    • Replaced FOTA_USE_DEVICE_KEY with FOTA_USE_ENCRYPTED_ONE_TIME_FW_KEY as the default value for MBED_CLOUD_CLIENT_FOTA_KEY_ENCRYPTION due to security vulnerability found in FOTA_USE_DEVICE_KEY.
    • Using FOTA_USE_ENCRYPTED_ONE_TIME_FW_KEY is a breaking change and requires a new bootloader that support this feature.
    • Deprecated the FOTA_USE_DEVICE_KEY option, which will be removed in a future version.
  • Added fota_app_postpone_reboot(). Calling this API postpones device reboot, which is required to complete the FOTA process, until the device application explicitly initiates reboot.
  • Changed fota_app_defer() behavior such that the FOTA candidate image download or install resumes only after the device application explicitly calls fota_app_resume().
  • Support calling fota_app_reject() after calling fota_app_defer().
  • Fix: Support for resuming installation after an unexpected interruption (for example, power loss) of a component image.
  • Added support for updating device firmware with a cloud-encrypted update image.
    • Enabled by the MBED_CLOUD_CLIENT_FOTA_ENCRYPTION_SUPPORT option.
    • Limitation: Not supported when MBED_CLOUD_CLIENT_FOTA_CANDIDATE_BLOCK_SIZE isn't 1024.
  • Fixed coverity issues.
  • Fixed compilation for Client Lite Linux, release mode. KVStore failed to compile in release mode.
  • Fixed a bug that prevented Firmware-Over-the-Air (FOTA) from running successfully after devices were provisioned in the production flow.
  • Fixed update flow when the update candidate version is 0.0.10.
  • Fota block device configuration changes: FOTA_INTERNAL_FLASH_BD changed to FOTA_INTERNAL_FLASH_MBED_OS_BD, FOTA_CUSTOM_BD changed to FOTA_CUSTOM_MBED_OS_BD, added default block device configuration FOTA_DEFAULT_MBED_OS_BD.
  • Changed FOTA application interface APIs:
    • fota_app_on_install_authorization(uint32 token) to fota_app_on_install_authorization() (removed token).
    • fota_app_on_download_authorization(uint32_t token, ...) to fota_app_on_download_authorization(...) (removed token).
    • fota_app_authorize_update() to fota_app_authorize() (reverted to the deprecated API).
    • fota_app_reject_update() to fota_app_reject() (reverted to the deprecated API).
    • fota_app_defer_update() to fota_app_defer() (reverted to the deprecated API).
  • On Linux targets, all FOTA related files (candidate, header and so on) were moved to the the configuration directory (PAL/KVstore).
  • Require defining MBED_CLOUD_CLIENT_FOTA_LINUX_SINGLE_MAIN_FILE in Linux MCCE, Testapp or any Linux app that has a single file update.
