SD S110 V7.0.0 DFU finishes at 51%, not 100%

I've made a modified version of the example DFU provided with SoftDevice v7.0.0-3 alpha that works in single bank mode instead of dual (because I need to bootload a huge app). My modification works and has been tested to work fine with MasterControlPanel.

I am now testing further with nRF Toolbox v1.6.0 on Android to do the uploading.

It works, sort of, the progress bar finishes at 51% and I get a notification saying that the file has been "send successfully". I am expecting the progress bar to finish at 100%

(note: the uploaded app appears to function, so it's not that big of a problem)

I suspect this is due to the fact that I've essentially doubled the available flash space but the Android app calculates progress based on the original amount of available space.

Please somehow redo this calculation.

(also, if you have time, it should say "sent successfully")

  • Hi ! I have the same problem when using Master Control Panel in Android (stops at 27% and fails). I using softdevice 7.0.0-3 and SDK 6.

    The DFU OTA upload works fine if I do it through Master Control Panel 3.5.1 on my PC. I tried to change the MRB size to 0 on the application as suggested on the forum, but no success... (Actually if I don't change the size to 0, the upload fails immediately).

    Your help would be really appreciated !
