How to run RSSI Viewer with custom board.

[JKOH]

Hi,

I want to run RSSI Viewer with my nRF52840 custom board to evaluate receiving performance of RF matching circuit.

The custom board has two communication path to a PC:

1. On board USB connector which is connected to D+,D- pins of nRF52840.

2. FT232 USB-UART break out board which is using TXD(P1.01) and RXD(P1.04)

Previously, I used #2 to run Direct Test Mode and it worked well.

But, I can't run RSSI Viewer with any of them. I could only get following messages.

==================================================================

==================================================================

Please let me know how I config or set up the custom board.

For your reference,

I have a nRF52840 DK board and it works well with RSSI Viewer.

nRF Connect for Desktop: v4.1.2

RSSI Viewer: v1.4.5

Hi,

for testing performance the RSSI viewer is not the way to go.. radio test is the FW to use and see RF performance test guidelines. 

Note that we offer to do HW review and can assist with tuning of radio matching network and antenna. 

Best regards,

Dear Kaja,

I appreciate your comment.

But I can't make fully featured test which is described in the guidelines due to limited environment.

So we are considering this test.

Would you let me know how to run RSSI viewer with custom nRF52840 board?

I just would like to see relative receiving performance.

Thanks.

Hi, 

the RSSI viewer require particular firmware according to the device, so custom board is not supported.

Best regards,
