direction_finding_connectionless_rx nRF5340dk rebooting after "Waiting for periodic sync lost..."

[Jpittevils]

I succesfully flashed both direction finding samples to two different nRF5340dk's, but the rx board keeps rebooting afer the "Waiting for periodic sync lost..." message, while the sample page says that the next output should be:

PER_ADV_SYNC[X]: [DEVICE]: XX:XX:XX:XX:XX:XX, tx_power XXX, RSSI XX, CTE XXX, data length X, data: XXX
CTE[X]: samples count XX, cte type XXX, slot durations: X [us], packet status XXX, RSSI XXX
"



any idea on why this is? It seems to me like this is stopping me from correctly reading out the IQ samples?

Hi

Do you build with the overlay-aoa.conf Kconfig enabled in both cases, and have you added the necessary child images mentioned in the documentation to run the Bluetooth LE controller on the network core, etc.? It should indeed work using West. Have you downloaded the nRFConnect SDK using the Toolchain manager app or manually?

Best regards,

Simon

I downloaded it using the Toolchain manager app. The child images are added automatically I think, but I think I am wrongly building with the overlay-aoa.conf Kconfig enabled. I first added the contents from overlay-aod.conf to /child_image/hci_rpmsg.conf and then I try to build with

west build -b nrf5340dk_nrf5340_cpuapp -- -Dhci_rpmsg_CONF_FILE=hci_rpmsg.conf

but this does not work.

Could you give me the correct command for building the sample projects for the nrf5340dk? I'm having difficulties understanding how to correctly add the Kconfig files to the child image and the project and I think that's where my issues come from.
