nRF Connect Desktop Bluetooth low energy app with PCA10056

[lCannon]

I am interested in having nRF Connect Desktop Bluetooth low energy app work with my PCA10056.  From:

https://devzone.nordicsemi.com/f/nordic-q-a/40155/custom-board-support-for-nrf-connect

The BLE app will only work with specific dev kits under specific circumstances.  From my understanding of the response in the link, it should work with the PCA10056 board on the nRF USB port (other then the USB attached jtag port which it will work on) with the firmware:

\examples\connectivity\ble_connectivity\pca10056\ser_s140_usb_hci\

installed.  Is this suppose to be the case?  When trying to open the port I get the error:

ERROR Unsupported device with serial number 'CD57CF158FCF' and traits ["serialport"]

Does the example require modification to work with the Bluetooth low energy app?  I am using app version V3.3.0 and SDK version 15.2.  For my situation I am not interested in it working on the JTAG USB port.  The port does enumerate properly on my PC as nRF52 USB CDC Connectivity and is seen by the Bluetooth low energy app, it just cannot connect to it.

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

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.
