This value defines the maximum length of the vendor-specific version information
|
||||
that the mesh stack can manage, describing the image. Please note that
|
||||
only 106 octets size allows the device to be compliant with
|
||||
the Bluetooth Mesh DFU specification. If smaller than 106 octets are set,
|
||||
then the device will fail with managing firmware images that have
|
||||
a longer vendor-specific version information.
