RSSI Measurement in Nordic N52840

I have n52840 chip, for Tx power measurement, I have used nRF connect for desktop v.4.2.1.

I used Direct test mode and in Transmitter tab using single channel mode. I have used used UART to set up connection with desktop and the chip.

In DTM mode we can able to transmit the power from the chip, that can be measured using at the other end with help of spectrum analyzer.

But to check received power I tried using RSSI viewer, but when I tried to connect the chip using UART it show " No pre-compiled firmware is available for the selected device"; "Error while setting up device" and "No device setup found"

My question is during DTM mode the connection with UART is established while during RSSI its shows Error messages?

What could be the reason and how to overcome?

Is there any way to measure received power in the nordic chip n52840?

    Thanks for the reply.

    Yes, get to know from your comment that for RSSI measurements we need to have two separate boards, on is acting as a TX and using DTM mode and the second one is used for RSSI viewer to check RSSi levels.

    But the thing is that when I connect my custom board with desktop and open RSSI viewer it shows error messages: No pre-compiled firmware is available for the selected device"; "Error while setting up device" and "No device setup found".

    How to resolve this error, then only the device will work.

    I connected board and desktop using UART, in direct test method mode connection is established with no issues but in RSSI viewer app it shows the above error messages.
