Hi Joakim and thank your for your response!

Seems I misused the term "buttonless" here, sorry about that. I wasn't aware there is such a thing as Buttonless Secure DFU Service.

What I'm really looking for is roughly similar behavior than with Nordic's DFU trigger library provides when using pc-ble-driver's connectivity firmware on nRF52840 dongle. Scriptable nRF sniffer firmware update with nRF52840 dongle is exactly what we would need.

It is the need to do a button press that is what you want to get rid of, right?

Adding the buttonless DFU like the pc-ble-driver has is doing DFU over Bluetooth.
Simultaneous Bluetooth and Sniffer is not possible without compromising the usability of the Sniffer.

There are other ways to get around the button press though, if all you need is something that is scriptable?

The nrf52840 dongle is the only board that has this requirement.
Using a nrf5240 DK and attaching the USB cable is an alternative.

Yes, understood. That is why I opened this feature request. :) I hope in future the sniffer firmware would have some kind of way to trigger it to bootloader mode without physically pressing the button. It does not necessarily be the exactly same way than in connectivity firmware.

Hi,

Buttonless DFU requires SoftDevice + DFU application. Something we are not using in the sniffer firmware.
