Android BLE DFU can't start

[Valentin Laurent]

Hello,

I have question, I'm actually developing an Android application and try to update the firmware on a device with a DFU process. It work on every mobile device except on one kind of mobile.

The probleme is that my DFU class doesn't want to be instantiate. I tried to create a new class, with only a empty constructor and it still doesn't work. It's very strange and I can't understand the logic behind this error.

Did you have any problem like this ? Do you have any clues or ideas to help me ?

Thank you a lot for your help.

Hi Valentin,

Please provide more information about the type of the phone, vendor, Android version. Could you confirm that same app works on other Android phone ?

Could you be more specific on "doesn't want to be instantiate", "still doesn't work." could you provide a screenshot or more detailed information ?
