OTA DFU Thread: merge with NCP.hex

[AS_Kalpa]

Hi all,

in my current platform I have:

1. a DK (we are working to implement HW modifications to use a nrf52 dongle for this purpose) that is performing as a Thread DFU server (following this example https://infocenter.nordicsemi.com/index.jsp?topic=%2Fsdk_tz_v3.2.0%2Fthread_example_dfu.html)
2. a nrf52 dongle that is running the NCP example under <SDK folder>/examples/thread/ncp/ftd/usb/hex

We would like to merge the two functionalities to use one single board to handle both.

Do you have any suggestions? 

I think the easiest way is to have:

• the source code of the NCP example (SDK/examples/thread/ncp/ftd/usb/hex) 
• the source code of the connectivity fw for Thread DFU purpose that is automatically flash by nrfutil ('-f') when you run the line:
  

  nrfutil dfu thread -f -pkg app_dfu_package.zip -p COMx --channel 11 --panid 43981 -r 4 -rs 5000 -a FF03::1

 so that we can merge them manually.

Is it possible? Am I missing something? Are there any issues that I'm not considering?

Thanks in advace,

Alessio

Hello,

Actually, the NCP example is the one being used when running the command "nrfutil dfu thread -f -pkg app_dfu_package.zip -p COMx --channel 11 --panid 43981 -r 4 -rs 5000 -a FF03::1". However, it is the uart version, and not the USB version. 

Try manually compiling the dongle using nRF Connect for Desktop -> Programmer, and then call your nrfutil call "nrfutil dfu thread -pkg app_dfu_package.zip -p COMx --channel 11 --panid 43981 -r 4 -rs 5000 -a FF03::1" without the "-f" flag. Does that work?

Please note that the COM port may change after you program it with the NCP example.

Best regards,

Edvin
