Is there an updated example for BLE on nrf5340?

That is lucky! Yes for example this dev academy course briefly covers the multi-core case and has an Exercise 2 titled "Custom board for Multi-core image" but it only covers the non-secure and secure image case, not the app image vs network image case: academy.nordicsemi.com/.../

Of course yes, the examples are useful to understandand and as a starting point, but a custom application is mandatory... somehow I managed to make it work but it's not so clear how

I have to agree that there is no clear guidance on how to setup CPUNET especially for a custom board. Even in all the links provided above. It just magically works with the peripheral_lbs example with no explanation...

Hi David,

Are you trying to create a custom application of your own, which can be flashed onto the nRF5340DK.?

Of course I followed the BLE fundamentals course, but even if it says it supports the nrf5340dk board I have not been able to make it work, since it needs different steps to program the net core. It is my fault for sure, so I kindly ask you to point me to the relevant part of the course where the sample application is built for the 5340.

As I wrote before the "lbs" example works, but I would prefer an explanation of how to do the same in my application rather than having to reverse engineer a sample to adapt to my use case.

Hi David,

I would suggest that you take a look at our DevAcademy Tutorials: https://academy.nordicsemi.com/courses/bluetooth-low-energy-fundamentals/

You could also take a look at the BLE samples here: https://docs.nordicsemi.com/bundle/ncs-latest/page/nrf/samples/bl.html

Well it seems that the peripheral_lbs example works out of the box, anyway it is quite complex (the build process and configuration, not the actual BLE code) so an explanation of the multicore build setup it uses would be very much appreciated 🙂

After flashing it on the board the error I mentioned above disappears, I suppose this means that the net core image is correct now. How can I make my project behave in the same way as the sample, so that it automatically creates the image for the net core and flashes it to the board?

Thanks
