DFU in multiprotocol BLE/Thread application

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
