Detailed Description

Handler callbacks that shall implement the platform-specific part of firmware update process.

The Firmware Update object logic may be in one of the following states:

  • Idle. This is the state in which the object is just after creation (unless initialized with either ANJAY_FW_UPDATE_INITIAL_DOWNLOADED or ANJAY_FW_UPDATE_INITIAL_DOWNLOADING). The following handlers may be called in this state:
    • stream_open - shall open the download stream; moves the object into the Downloading state
    • get_security_config - shall fill in security info that shall be used for a given URL
    • reset - shall free data allocated by get_security_config, if it was called and there is any
  • Downloading. The object might be initialized directly into this state by using ANJAY_FW_UPDATE_INITIAL_DOWNLOADING. In this state, the download stream is open and data may be transferred. The following handlers may be called in this state:
    • stream_write - shall write a chunk of data into the download stream; it normally does not change state - however, if it fails, it will be immediately followed by a call to reset
    • stream_finish - shall close the download stream and perform integrity check on the downloaded image; if successful, this moves the object into the Downloaded state. If failed - into the Idle state; note that reset will NOT be called in that case
    • reset - shall remove all downloaded data; moves the object into the Idle state
  • Downloaded. The object might be initialized directly into this state by using ANJAY_FW_UPDATE_INITIAL_DOWNLOADED. In this state, the firmware package has been downloaded and checked and is ready to be flashed. The following handlers may be called in this state:
    • reset - shall reset all downloaded data; moves the object into the Idle state
    • get_name - shall return the package name, if available
    • get_version - shall return the package version, if available
    • perform_upgrade - shall perform the actual upgrade; if it fails, it does not cause a state change and may be called again; upon success, it may be treated as a transition to a "terminal" state, after which the device is expected to reboot
