How do you: "manually put the device in bootloader, i.e. send 0x01 to the control point of the service."

Any updates on this?

No, I am afraid that I do not know when this will be implemented.

Great, thanks for the response, I look forward to a new buttonless DFU app in the future release! Can you share a estimated date of when that might be?

Yes, you have to manually put the device in bootloader, i.e. send 0x01 to the control point of the service.

The buttonless DFU feature with bond sharing in the legacy bootloader has been removed in SDK v12.0.0 since it made it possible for any device to put the device in bootloader mode and update the firmware. Allthough we have introduced signed firmware images in SDK v12.0.0, it is still possible to send fake images with an incorrect signature, which can lead to the application being deleted if for instance a single bank bootloader is used.

Thus, we do not currently provide any offical support for this feature, but you are free to add this feature to your own application using our DFU library.

We are looking into this and will add a better buttonless DFU feature to the SDK in a future release.

-Best regards
