Device Management Client

Known issues:

  • [Linux/Zephyr] Asynchronous DNS does not work well, and the device fails to reconnect to the cloud if some of the pods are restarted. In such a scenario, the device needs to be restarted.
    To address this issue, the default DNS settings should be overridden to synchronous DNS in the application level:
    • For Linux devices, set the PAL_DNS_API_VERSION flag to 0.
    • For Zephyr devices, set the DNS API selection to POSIX.

Changes:

  • Izuma branding changes.
  • Support for multiple ciphers via config flag PAL_MAX_ALLOWED_CIPHER_SUITES.
    • This is required for improved LwM2M compliance.
    • Please ensure your TLS configuration also enables the required ciphers.
  • Add support for parsing Pkcs#7 certificate format. This format is used in EST flow.
    • This is required for improved LwM2M compliance.
  • Developer flow only: The device goes through a storage reset if the compiled credential file differs from the stored credentials.
  • In LWM2M_COMPLIANT mode, use Bootstrap server CA as LwM2M server CA for enabling server certificate verification during TLS handshake.
  • Fix compilation issue with glibc 2.34 and newer where PTHREAD stack sizes have been changed to runtime variables.
  • Alternating port fallback function for MBED_CLOUD_CLIENT_CUSTOM_URI_PORT added.
    • If a socket error is encountered, the next try will be done with the original CoaP port 5684.
    • After 2nd failure, we alternate back to the custom port.
    • NOTE! Only port 443 can be used as an alternative customer port with Izuma Networks.
