Upload failed when performing DFU over BLE

[littlebei]

Developed with SDK 15.0.0. and s132_nrf52_6.0.0_softdevice

After I generate the DFU package, and upload it with nRF Toolbox, it will returns "Upload failed: REMOTE DFU INVALID CRC ERROR".

The code for generating the package:

nrfutil.exe pkg generate --application app.hex --application-version 2 --hw-version 52 --sd-req 0xA8 --key-file priv.pem DFU.zip

I don't know where the CRC code comes from. In the setting page of bootloader, I found CRC and Application CRC as below.

Hei ,

 

Could you try follow my guide here and let me know if you have the same issue. Please try to update first with an example in the SDK, ble_app_hrs for example (not the precompiled hex, as it contains the softdevice).

Thanks a lot, It works well now.
