@ed-bonnet Thanks for the reply, I am not using flutter_downloader i use S3 to get the firmware file. How did you manage to find what was preventing the call being made?

@l984-451 reverting back to version 3.3.0 was the only thing that worked. But even then, there was a problem with a Lenovo tablet on which DFU stubbornly refused to work because the DFU target wasn't found by the library. So, to fix this follow up problem on the Lenovo, you'll have to start a DFU scan and keep it running/scanning before starting the firmware update. This way it's going to work reliably.

Hello, I had this issue and my workaround was to remove flutter_downloader (used in my app to get the firmware file).
The isolated process seems to be the issue. When flutter_downloader was called anywhere in the app, the DFU could not trigger any events.

Same issue on Android 10 after updating to version 4.0.0. No issue with version 3.3.0 though.

Did you find a fix for this? I have the same issue on Android and iOS.

I still have the same issue. No call backs is ever called, so no way for me to actually know when/if the dfu transfert has ended properly.
