Is there an eval program to view/record RSSI?

[EdT]

I am in the process of evaluating the NRF52840dk and the NRF52840 dongle. I would like to have a program that will show, or record, RSSI data between units, or a unit and, say, a cell phone. Is there any simple way to do that without having to write a lot of code? I'm just trying to do a quick evaluation at this point, and I suspect the code is already available, or something that covers that need for evaluation.

The nRF52DK and the nRF52840 dongle can both be used with the nRF connect app, one of the applets within the nrf connect tool is called RSSI viewer. 

Plug in the dongle and select it as the device from the drop down list and it will show you the RSSI values. 

It is also possible to measure RSSI with the nRF connect app for iOS. You would still need to program the device you're measuring with an example application so that it is advertising, look in the example/ble_pheripheral/ for examples the HRS or heart rate sensor example is easy to program.
