iOS-DFU-Library: Data size exceed limits error – differs from Android to iOS?

[JAL]

When flashing files from an iOS device I run a lot into data size errors (not always), when using the same files on Android they can be copied without a problem.

It looks a like the error comes from the library on iOS. I am using the same microcontroller for both systems.
Is there a difference in checking if a file is too large on iOS and Android and if so, how can this be changed on iOS, as this is legacy from the library?

Hello,

Which versions of both libraries are you using?

Can you provide some logs from iOS?

Hello Aleksander,

thanks for your fast reply!

we are using 4.11.0 on iOS. I don't know the number of the (working) Android version right now...
