Error while performing dfu

[Zolu]

Hi,

I am trying to perform DFU over mesh network. I am following the steps as given in this .

I could achieve the steps from 1-6. But while running the command for Transferring the DFU archive over serial with nRF Util i.e. nrfutil dfu serial -pkg dfu_test.zip -p <COM port> -b 115200 -fc --mesh; I am getting the below mentioned error:

nrfutil dfu serial -pkg app_dfu_package.zip -p /dev/ttyACM0 -b 115200 -fc --mesh
Usage: nrfutil dfu serial [OPTIONS]
Try "nrfutil dfu serial --help" for help.

Error: Invalid value for "-fc" / "--flow-control": --mesh is not a valid boolean

OS : Ubuntu 20.04

nrfutil version : 6.1.0

nRFMesh SDK v5.0

nRFSDK v17.0.2

Any help will be highly appreciated.

Regards,

Zolu

Hi,

For mesh DFU you need a special version of nrfutil:
https://github.com/NordicSemiconductor/pc-nrfutil/tree/mesh_dfu

With that version, you should be able to follow the guide.
