is nrfutil 6.1.2 incompatible with softdevice version 6?

Then my remaining suggestion would be to use two different devices, one for the DFU and another for everything else.

Production, Dfu for another device

I would like to refrain from repeated reflashes for my device

Is this for use in development or production stages, or will this also be used in the final product?

While not a perfect solution it is possible to use the USB bootloader to change the firmware in the dongle or kit when you want to do DFU, as explained here. Then you basically need to switch between two sets of connectivity firmware, depending on whether you want to do DFU, or want to use some other application.

Alternatively it should be possible to use two dongles as well, and have a dedicated one for DFU using v5 of the connectivity firmware.

I would like to allow my custom usb peripheral to perform a dfu with the already implemented code of nrfutil rather than rewriting that service myself

Apparently we have no concrete plans to provide python bindings for v6 of the SoftDevice unfortunately, we only have the C bindings for this.

Can you let me know what you would need v6 support for?

Thanks,

I appreciate the effort

I have attached the patched SDK I was referring to:

devzone.nordicsemi.com/.../4101.v15.zip

devzone.nordicsemi.com/.../0880.sd_5F00_api_5F00_v5.zip

I will have to check this internally. I will do my best to get back to you on Monday.

I am running a custom pcb, quite similar to pca10056.

I had seen the pc-ble-driver sources and compiled them on my own if that's the patch you're refering to.

What would the python binding and nrfutil require in order to make them compatible with version 6?

is it just linking against a newer version of pc-ble-driver? or is pc-ble-driver-py (currently supporting pc-ble-driver 4.1.2) not supporting v6 despite pc-ble-driver suggesting it does?

The Python bindings are only compatible with version 5 of the SoftDevice unfortunately.

There is a patch available to make the connectivity examples in SDK v15.3.0 work with v5 of the SoftDevices, and I can share these with you if it could be of use.

Are you running the connectivity firmware on a custom board, or one of the devkits?
