when i use nrf exaample -direction_finding_connectionless_rx,the tx and rx i build wnd program to boards,but a error begin,can you tell me the resons?if can,have a solution?

[swz_nordic]

 I use the nrf examples direction_finding_connectionless_rx,firstly i have no attena array,the other as describled i do by steps.

I use two nrf5340 boards.with building,i find some errors,then i make some configtions.

The i flash succefully.i use the serial comport to debug,there has error.code (-5)

but i can solve the problem,i need help.

Hi

First off, to be able to get useful data on the RX side, you will need an antenna array. You can contact our regional sales manager of your area for more information on how to get one. If you need help getting in touch, let me know and I can contact them for you.

I also see you're using the direction finding sample projects in the Zephyr path. I would suggest building from the nRF path as those samples are specifically made for the nRF52/53 series boards. Not that it should make much of a difference in the direction finding samples. Then I would also recommend reading through the documentation thoroughly, as there are some board specific configuration for the BLE controller on the nRF5340 DK. (TX sample here)

Error -5 from the bt_le_scan_start() points to a I/O error while trying to scan, which is likely the pins for the antenna switching on the antenna array not being set up correctly (since you don't have an antenna array).

Best regards,

Simon

very thanks,i know your suggestion,as the example describled,i configure the my project.

Firstly,There has a little deffrence between the nrf direction and zephyr direction.

zephyr notes antenna array(optional),i think that it can be used to accept iq without antenna array.

I don't learn about antenna array,it may be a another meaning.this is my doubt,

 

Secendly,the network core need to be build alone, i tay as the Multi-image build described.I flash the hex file to board ,but it don't find files.may understand wrong,can you tell me how the network core is build and flashed?

I  try nrf examples direction,but there is problem as the same as network.i can't solve the problem.

Now i want to get a antenna array,i live in dongguan city ,guangdong provice in china.I don't have the nodic agent's contact way in here.my phone number is 13972143171,mail deress is [email protected].

if you can touch,please touch me,very thanks.
