Upload failed: UNKNOWN (8202)

mcau1

Hi,

I am working on implementing secure DFU. I have complied and loaded the secure DFU using gcc and am trying to upload a package using nRF Toolbox on android.

I have a package zip file which I built from an example hex (dfu_test_softdevice_s132.hex) using nrfutil. I can connect to the DFU and start the upload then I get the message. Upload failed: UNKNOWN (8202) from the app in the phone.

Not sure how to solve this one.

    If you're using SDK v12.x then you're using S132 v3.0.0 which has 0x8C as firmware ID, not 0x80. Could you try to create an image with the command below?

    nrfutil pkg generate --hw-version 52 --sd-req 0x8C --application-version 4 --application Test4.hex --key-file Key2.pem DFU_test4.zip

    You could also try to create a package with the --debug-mode option so that you skip the version checks.
