DFU in multiprotocol BLE/Thread application

[marmio]

Hi,

1. I'm developing multiprotocol BLE/Thread app with Thread SDK 1.0 and I want to ask if there's a possibilty to perform DFU over Thread in that case? In Thread Secure DFU Example description there's something like this written:

"The Thread stack does not use the SoftDevice, but the --sd-req 0x00 option is required to indicate that no SoftDevice is used."

So what in case of multiprotocol solution? Do I need just to insert the number of SoftDevice?

Thanks in advance,

Marek

Hello Marek,

This field used in nrfutil, --sd-req 0xNN is used only for the bootloader to not accept a DFU pack that does not fulfill the requirements.

So if your application is using multiprotocol; BLE and Thread, and the BLE part requires the softdevice (which it probably does), then you should use the --sd-req that fits to that softdevice.

 

You may know this, but you can see the list of softdevice IDs by typing:

nrfutil pkg generate --help

 

Best regards,

And what do I have to add to my app, only coap dfu init, process and trigger functions, and all their dependencies?
