This section explain how to update the updatable components of MBL, including your applications. For updates, we provide two workflows: one using MBL CLI, the other using the manifest tool.
An MBL device can only be updated if the following are available:
The device is running an MBL image that can connect to a Pelion account. Please install an image and provision your devices before you continue.
The build artefacts for the image to send as the update payload. See the build tutorial for instructions.
An internet connection on the device. Follow the instructions to set up an internet connection.
The directory in which the manifest tool was initialized, as reviewed in the development environment setup.
This must be the directory from which the
update_default_resources.cfile was obtained when you provisioned your device.
A Pelion API key, to use the manifest tool from the command line. Follow the instructions in the requirements section to obtain an API key (when prompted to select a group to set the API key access level, select Developers). Make a note of the API key to use it later; for security reasons, the portal will not display it again.
