I believe that if you apply the relevant changes from the patch to the normal SDK, you should be able to build the connectivity firmware using SES. The process in the repository is to enable easily building of many connectivity firmwares for different chips/boards/softdevice APIs.

Note that the SDK used (SDK 15.3.0) does not support softdevice v3.1.0, it will have to be added similar to how the build system in pc-ble-driver adds it.

Thank you for your reply,

The connectivity_4.1.1_usb_with_s132_3.1.0.hex does work on the nRF_USB port as you said using the PCA10056 board. We are very interested in using it as the start of a project. We are working with SES as our build and development environment. Our immediate goal is to be able to build a file equivalent to connectivity_4.1.1_usb_with_s132_3.1.0.hex using SES. We could then modify it for the specifics of our board. Our ultimate goal is to have our board work as a dongle for the Desktop nRF Connect Bluetooth Low Energy app by making it look like the PCA10056. Is being able to build a file equivalent to connectivity_4.1.1_usb_with_s132_3.1.0.hex using SES something that can be readily done? I see a completely different build system then SES being described in the GIT repo and we would not want to switch development environment. If we can, is having our board work with the BLE app by appearing as the PCA10056 demo board something that seems feasible?

Thank you for your help.

Hi,

The connectivity firmware used by nRF Connect is slightly modified compared to the stock serialization firmware in the SDK (see this patch).

You can flash the connectivity hex from pc-ble-driver repository (connectivity_4.1.1_usb_with_s132_3.1.0.hex) to your board, and it should work with the nRF_USB port of the PCA10056 board. As far as I know, nRF Connect currently only supports up to softdevice API v3.

Best regards,
Jørgen
