How to get RSSI in the direction_finding_connectionless_rx example on nRF52833?

[Sener]

Hi,

I want to simply get RSSI at each scan in the connection less example (direction_finding_connectionless_rx).
I have running two nRF52833-DK. One is flashed with RX and the other with RX example.

I'm using the nordic NCS SDK v1.8.0 with softdevice s140 v7.3.0.

The devices are communicating to each others nice and easy. But, RSSI readings at each scan show a constant value (-127)

When I debug it (using RTT Viewer and Debug terminal), I get this;

RSSI looks always -127.

I can only see some different RSSI readings during initial talk between the two devices (anchor and tag)

Any input greatly appreciated.

Hi Simon,

Thank you for your inputs again, I will put your suggestions in practice soon.

I have also replied by Patrick this morning and he has also mentioned your support, I am grateful. And thank you very much for the antenna design.
I am going to order a few PCB right away. Only think worries me that PE42442 (SP4T RF Switch) is not in stocks anywhere. I will check it a bit more.

The CONFIG_UART_CONSOLE should be set in the prj.conf file of your project C:\...\v1.8.0\nrf\samples\bluetooth\direction_finding_connectionless_tx\prj.conf

Ah, I should have seen that. Thanks.

Other examples using RSSI include I.E. the central_hr sample that will detect and print the RSSI of advertising heart rate monitor peripheral samples.

Let me see that, thanks.

Best regards,
