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

No, you don't need this overlay-aoa.conf file in the locator application.

I would select the projects found in the \ncs\v1.8.0\nrf\samples path rather than the Zephyr path if I were you, as those are specifically tailored for the nRF52833 and NRF5340 devices.

If you're new to development with the nRFConnect SDK I would recommend using the Visual Studio Code and the nRFConnect SDK extension, which lets you add overlay files when setting up a project for example. Do you have an antenna array on the locator side and have you configured the antenna matrix to work in Angle of Arrival mode as explained in the documentation? This is required to get correct results.

Best regards,

Simon
