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 have an antenna array connected to your nRF5340DK? To make sure everything is configured correctly, please also read through the README.rst file that is located under C:\...\ncs\v1.7.0\nrf\samples\bluetooth\direction_finding_connectionless_rx. I'm assuming this is due to bad sensitiviry either in the receiver or transmitter on your end.

Best regards,

Simon

Hi, I do not currently have an antenna array connected, I wanted to make sure the software compiles and everything works before buying extra hardware. In the readmse.rst file it mentions a nordic designed 12-patch antenna array, is this up for sale somewhere?

Is it possible to test if the software is working as intended before buying this extra antenna patch?

thank you very much
