BLE Sniff Channel Support

Hello Nordic,

We have recently purchased an nRF52840 Dongle. We were able to sniff the BLE packets over the air. So it is found that all the packets that we are able to see in the capture are from the primary advertisement channels in BLE so I would like to query that if it is possible to have any firmware or hexadecimal file which can actually give a feasibility for us to capture the packets not only from the primary advertisement channels but from the entire spectrum of the BLE. 

And we would also like to query that if this thing that we are observing is it a hardware limitation or it is a firmware level limitation.

Thank You!
