nRF Toolbox 4.2.0 with support for buttonless signed DFU?

Adrian Eggenberger

Hi

The new signed DFU in the SDK12.1 comes along with a experimental buttonless DFU. There are a few bugfixes required to make it working, but the nRF Toolbox app didn't support the buttonless DFU. In fact it was necessary to force the application to reset to bootloader by another tool (e.g. LightBlue). In the release notes of the nRF Toolbox 4.2.0 on the iOS App Store a new feature "Experimental Buttonless Secure DFU feature" is listed. I thought that now the app should support the buttonless feature from the SDK 12.1, but i couldn't make it work.

Could someone explain what should work with the nRF Toolbox and what are the plans for upcoming releases. Is this buttonless DFU the way to go or will something new be introduced with upcoming SDK releases (heard some rumors in that direction).

Regards Adrian

    Hi Adrian,

    We were working on DFU Libraries some time ago and added support for the Experimental Buttonless feature for both Android and iOS. However, the iOS nRF Toolbox app has not been updated back then and it's still using the library without this feature. Sorry!

    We will release nRF Toolbox v4.3 shortly which will use the DFU Library 3.0.6. We will also print the version of the DFU Lib on the DFU screen to avoid misunderstandings in the future. For now you may use the Example app (but you'd have to compile it yourself (pods try iOSDFULibrary) to include your own ZIP file there. However, the verification process in Apple is now fairly quick so the update should be visible in few days.

    There are no more changes in the nRF Toolbox 4.2->4.3 except upgrading DFU Lib version. I'll come back to you when the app is online.
