Hello,
I am trying to use a nRF52840 Dongle to perform DFU over Thread: I am using a PCA10059 board, already provided with the default bootloader. I also programmed the board with the connectivity firmware provided by repository pc-ble-driver: I used pre-compiled hex files provided in the hex folder of the repository (I don't know exactly which branch I should use; I focused on the release branches)
When I run the nrfutil command to perform DFU over Thread, I always get the same error:
The firmware I tried is the connectivity_4.1.1_usb_with_s140_6.1.1.hex but I also tried other versions, as the 4.1.4 release.
I would like to know the following:
a) which repository branch to use
b) which sd_api version to use (I suppose sd_api_v6 is the one to be used since it's the latest)
c) if I should make changes to the source code to adapt it to the PCA10059 board
d) if the source code is available somewhere (I know the code is based on SDK/example/connectivity/ble_connectivity but I also know there are patches to be made..)
Thanks!
