Did it work when testing with nRFToolbox on iOS ?

On PC, if you want to support bonding and buttonless, you may need to modify the nrftutil source and add your own code. Simply add option to switch from application to bootloader (no bond) should be fairly easy though.

Yes, I changed the setting in nRF toolbox on Android. I wasn't aware of the nRFtoolbox for iOS at the time; I did the tests with nRF connect.

Too bad that the nrfutil doesn't support bonding and buttonless DFU.

Hi,

You mean it worked now after you changed the setting in nRFToolbox on Android ? I suggest to test with nRFToolbox on iOS.

I don't think nrftutil supports buttonless ( and no bonding ).

I was supposed to check the Keep bonding information in the DFU settings. Same thing applies to nRF Toolbox for Android.

iOS nRF connect also started the DFU process but it didn't finish gracefully - I had to rebond the device on the iPad. I'll investigate.

nrfutil v3.2.0 didn't start the DFU process at all. I couldn't find any setting for it to start a buttonless DFU.
