Invalid object on DFU

[Cyril Hruscak]

Hi,

When trying to update an app using Secure DFU, we get invalid object error. The error comes from dfu_decode_command.

Using nRF5 SDK 12.2.0 on custom nRF51822 board. Update package was generated with nrfutil version 2.1.0. Trying with nRF Connect on Android device.

Any idea what could be wrong? Log file attached Log 2017-03-03 091650.txt

Hi Cyril,

Could you tell how do you generate the update package ? Invalid Object error return could be from:

The data object did not match the firmware and hardware requirements, the signature was missing, or parsing the command failed.

Do you set any version ? Note that hardware version should match with your chip , this case it should be "--hw-version 51"
