Sniffing Extended advertisement using NRF Sniffer 4.0

[venkatesan.m]

I am using NRF5240 board and and the latest Sniffer Software 4.0 (which claims Extended Advertising support).

Able to sniff all 3 advertisement channels (37, 38, 39) and Could see ADV_EXT_IND PDU.

Could you please help thow to see the Extended Packet Information which are sent over the data channels.

Log Snippet:

3 0.000 Anonymous LE 1M LE LL 7 72µs 0 ADV_EXT_IND

Wireshark has Adv Hop [37, 38, 39] accepts only the 3 values.

Hi

The nRF Sniffer only sniffs the advertising channels (37, 38, 39) and is not able to sniff the secondary data channels I'm afraid. 

Best regards,

Simon

Is it a bug or still the nrf sniffer does not support the extended advertising sniff.

It is not a bug. We have not yet implemented functionality for the nRF Sniffer to operate on the secondary data channels.

Best regards,

Simon
