nRF9160 Delta update 1.3.1 -> 1.3.5

[optical]

We have support for delta updates for our devices, however, it supports only a single delta update file at the time. Is it possible for Nordic to create a delta update from version 1.3.1 to 1.3.5? We would have to currently do updates from 1.3.1 -> 1.3.3 -> 1.3.4 -> 1.3.5 we would like to perform the update in a single step.

Due to the lack of support for FMFU from to side of nordic for mobile application, we are currently only capable of using the delta updates.

Or at least from 1.3.3 -> 1.3.5

Hello Tomas, 

There is a limitation to how many changes there can be between each version, in order to fit inside the "DFU area" when updating OTA.

Due to this delta updates must be done successively i.e. 1.3.1 -> 1.3.3 -> 1.3.4 -> 1.3.5.

Kind regards,
Øyvind
