nRF51 sniffer dongle not capturing secondary channels

[GowthamPV]

I'm using nRF51 sniffer to capture BLE packets for group of devices. Sniffer can able to capture only primary advertisement channels and not secondary advertisement channels / data channels. Please clarify can we capture channels (1-36 ) using nRF51 sniffer.

Also,

Is it possible to configure nRF51 sniffer application to additionally sniff packets from specific data channel ? (Like channel 31)

Hi, 

No, you won't be able to capture secondary channels, the sniffer only scans the three primary advertising channels (37, 38, and 39).

Is it possible to configure nRF51 sniffer application to additionally sniff packets from specific data channel ? (Like channel 31)

So by default the sniffer will hop between channels 37,38 and 39. If you want the sniffer to only capture packets from only one of the primary channels, I think in the nrf sniffer interface you can change the values in "Adv Hop" to for example 37, 37, 37.

Hi Mttrinh ,

Is there any nordic product / board which we can use as sniffer to sniff secondary channels?
