SDK 15 and Mesh 2.0 Generate a DFU file with nrfutil - ValueError

We used nRF5_SDK_15.0.0_a53641a and nrf5_SDK_for_Mesh_v2.0.0_src.

We are following DFU quick start guide http://infocenter.nordicsemi.com/index.jsp?topic=%2Fcom.nordic.infocenter.meshsdk.v0.10.0%2Findex.html

For nRF52:

mesh-sdk$ nrfutil dfu genpkg --application bin/blinky/blinky_nrf52832_xxAA_s132_5.0.0.hex \
--company-id 0x00000089 \
--application-id 1 \
--application-version 2 \
--key-file private_key.txt \
--sd-req 0x009D \
--mesh dfu_test.zip
We used "--company-id 0x00000089 \" to match Step 2 public key:
{
"bootloader_config": {
"bootloader_id": 1,
"bootloader_version": 1,
"company_id": 89,
"application_id": 1,
"application_version": 1,
"public_key": "ed09a58df6db5cd15b8637304f31d31f4042492ed7c7e4839fbe903f260a2ba1a855e92b72885825481ad56282bcf549ad7455ec46f000f0f62d97eeec883ba6"
}
}
The hex we used is C:\Nordic\nRF5_SDK_15.0.0_a53641a\mesh_sdk\bin\blinky\blinky_nrf52832_xxAA_s132_5.0.0.hexblinky_nrf52832_xxAA_s132_5.0.0.hex
We got ValueError, please see attached screen shot. 
Please advise.  Thanks

  • I have tested the DFU quick start guide using both Mesh SDK v2.0.0 & v2.0.1 & I receive the exact same TypeError as you do. I will mention this to the developers of nrfutil & see if they have any suggestions.

    Update:

    There was an issue with the python device_page_generator.py file. Should work if you download this file & copy it into the tools/dfu folder. I do not get any errors with step 4, but have not had time yet to test the rest. Could you please let me know if everything else works fine? If it does not, I will test a bit later.
