See RSSI values for all 3 advertising channels like on nRF Sniffer

[Ludger]

When I use the nRF Sniffer on a 52840 or 52832 with Wireshark I can see the RSSI values for each advertising message for all 3 channels (37, 38, 39).
So for each advertising message I have all 3 RSSI values.

Now when I program a scanner on the 52840 DK with the S140 soft device, I get only 1 RSSI value for each advertising message.

How can I get all three RSSI values for each single advertising message received?

Is there any source code or any equivalent example available how to implement this? It would be very helpful to have some resource to start from rather than implementing this from scratch.

Unfortunately, the source code for the firmware is not available. Also, I'm not aware of any similar code examples.
