Firmware Versioning

The firmware of all embedded devices has a format of X.Y.Z, where:

  • X is the major version number,
  • Y is the minor version number and
  • Z is the release version number

The two most significant numbers (X and Y) are derived from the general version for all SmartBridges.

The least significant number (Z) is derived from the actual application and is increased for firmware builds using the same base version. Whenever a firmware is built with a newer version of the general release, this number is reset back to 1. It is also worth noting that this number is always incremented by 2 (e.g. Z = 1, 3, 5, etc.).
