Hi!

I've reached out internally about this and will get back to you as soon as get an answer. From what I could find myself we don't have anything similar in the nRF5 SDK, but using Dual-bank updates background DFU should be possible using the experimental background DFU library. As for the HID configuration channel this seems to be a proprietary implementation for the nRF Desktop application, but it should be possible to implement something similar using the USB HID API of the nRF5 SDK.

Best regards,
Carl Richard

Thanks Carl,

So i have two questions:

1. configuration channel is developed by our RD,right? i thought it is open source, so i guess i was wrong.

2. this is new feature, will not add to nrf5 SDK according to our rules. right?

Regards,

William.

Hello again, William!

Apologies for a somewhat late answer.

1. You are correct that it's developed by our R&D, but it is actually open source. You can find the code under nrf_desktop/src/util. 
2. This is most likely correct. I don't believe we will do a big addition like this to the nRF5 SDK.

Best regards,

thanks, Carl,

one more question, "configurator_cli.py" under folder "ncs1.6.0\nrf\scripts\hid_configurator" is also provided by our R&D, right?

i tested usb hid feature DFU, it still costs about 5 minutes( ble hid feature dfu costs about 15 minutes),is it possible we can make this timer shorter? like  2 minutes for usb.

Regards,

William.

Hi again, William!

Yes, the HID configurator is also provided by our R&D. 

For the DFU speed question I will need to reach out internally. I will get back to you soon!
