Try downloading the pre-compiled library from here:

https://github.com/NordicSemiconductor/pc-ble-driver/releases

i.e. download the nrf-ble-driver-4.1.1-linux_x86_64.tar.gz, and find the .so in the lib folder.

Hi Sigurd

I still can't work well, after read the links you provide,

Here is my understanding based on RPI with 52840 dongle( I use 52840 dongle first to reduce complexity, using 52832 custom board is the future task)

- In my PC environment, nrfutil5.2 + dependently pc-ble-driver ( which is "pc_ble_shared_sd_api_v3.dll),

I can do dfu-ble to remote device.

- So my choice is to install nrfutil5.2 + linux-pc-ble-shared-sd-api_v3.so for my RPI.

But it's difficult for me to build pc-ble-driver for ARM platform, because vcpkg for ARM

Their are a unofficial pc-ble-driver version from:

https://devzone.nordicsemi.com/nordic/nordic-blog/b/blog/posts/accessing-the-softdevice-api-from-python-with-pc-b

But the version is too old (sd-api-v1), so could you provide pc-ble-driver-v3 of ARM platform or guide me how to build it for ARM platform?

Regards.

Joseph

[quote user="josephwei"]So is "serial_port_enum" can still work in your environment?[/quote]

You probably need to make some changes to the script to get it working with the dongle. See this and this post.

Hi Sigurd:

Thanks for reply,

Today I do many compatibility test,

So far I only can do DFU-BLE for other device as following setting:

- on a windows10 PC with python2.7,

- no matter nrfutil3.5 or 4.0 or 5.2

- 52840-dongle with a firmware from nrf-connect-pc-programmer-1.3.1 auto download

One thing I want to confirm, my 52840-dongle with the firmware from nrf-connect-pc, but when I run "python2.7 serial_port_enum.py NRF52",

There is show "0 serial port found" (see following), but DFU ble is working)

So is "serial_port_enum" can still work in your environment?

Regards

Hi,

1) nrfutil is really a python application, and I would think you can use it on the Raspberry Pi as long as you have all the requirements installed. I would start by trying to install it using pip with "pip install nrfutil". You can find more information on GitHub. Some other relevant posts: link 1, link 2, link 3

2) In order to create connectivity firmware that is compatible with custom nRF52 hardware you have to apply the patch found here (nRF5_SDK_15.3.0_connectivity.patch), to the connectivity example in SDK 15.3. You can find the connectivity example in SDK_FOLDER\examples\connectivity\ble_connectivity\pca10040\ser_s132_hci. You can then change the pinout in pca10040.h or create a custom_board.h to match your custom hardware pin settings.

3) Based on the description on what you want to do, then yes.
