Hardware Version

All fields not described below remain unchanged from version 3.

Activation (1 bit)

The Activation field is used to advertise if the receiving node must delay the actual firmware activation after the file transfer.

A node advertising no support for “activation” in the Firmware Meta Data Report Command MUST ignore this field and activate the Firmware immediately after download.

If the receiving node advertises support for Activation in the Firmware Meta Data Report Command:

  • The value ’1’ MUST indicate to delay the actual firmware update.

    When delaying the firmware activation, the supporting node MUST set the Status code field to 0xFD in the Firmware Update Meta data Status Report Command.

  • The value ’0’ MUST indicate that the receiving device MUST NOT delay the firmware update and activate the firmware immediately after download.
