1.5.5 Firmware Upgrade Service

The PRIME Stack uses the Firmware Upgrade service library to handle all operations related to device over-the-air updates and the storage of image files in non-volatile memory.

It also manages the version switch between PRIME v1.4 and PRIME v1.3.6 in the Service Node in case the PRIME Stack detects that it is not running the version of the PRIME network the node needs to connect to.
