HI,

I tried to test all projects, but I ran into a problem，project create like this

I just downloaded the routine and didn't change anything， but I cannot create advertiser 

this is UART output

I don't know what's wrong, and I can't find the meaning of err code

Hi,

What version of the NRF5340 kit do you have? (it should be printed on a white sticker on the board)

NRF5340 PDK, PCA10095,version is 0.8.0

Hi,

I think that the issue could be that Segger Embedded Studio does not flash the child image, hci_rpmsg, to the network core on the nRF5340. If you build using west, then this should be done automatically starting from NCS v.1.4.0. The hci_rpmsg image should be located in your_build_folder\hci_rpmsg\zephyr

You could try to flash it manually, using nrfjprog. e.g. from inside the build folder:

nrfjprog --program hci_rpmsg\zephyr\zephyr.hex --sectorerase --coprocessor CP_NETWORK

or using the Programmer app in nRF Connect for Desktop.

PS: The nRF5340 Preview Development Kit (PDK) has now been replaced with the nRF5340 DK (built around the production version of the nRF5340). The nRF5340 DK is also available through Nordic’s distribution network.
