Where is the source to the app?

Hi Roland,

Sniffing the frames of the application nRF51-multi-role-conn-observer-advertiser-master: the advertising app 2 Advertisers nRF51822 (ADV_IND) and Timesolt adv (ADV_SCAN_IND) on the same device If I choose to sniff the device Timeslot adv it works find and I got frames forwarded to wireshark If I choose to sniff the device nRF51822, the sniffer doesn't send any frame to wireshark. if don't choose to sniff a particular advertiser I got the frames from nRF51822 and Timeslot adv.

To verify if the problem is coming from my dongle PCA 10000, I plug it on a windows machine and with the same sniffer firmware, I use the ble-sniffer_win_1.01_1111. I can select the advertiser nRF51822 and got the frames in wireshark.

So it seems that for a strange reason ble-sniffer-osx is not forwarding the frames in this particular case.

Works well for me on Yosemite. However I have preferred 1.10.x for Wireshark as the 1.12.x Wireshark dissector for BTLE seems to have some funny naming on the SN/NESN bits and also for the length field of the packet.

Cool - hope it works well for you. As stated in the install notes (somewhere) you can also use my RKNRFGO package (also on Sourceforge) to load the code onto the PCA10000, or any of the other supported Nordic boards, if you prefer to use something graphical.

Hi,

Thanks for sharing. Did the installation without any problem. Use the JLinkExe command from Segger software to load the firmware on a PCA10000. Cheers, Claude

Sorry no, I've never used ANT and know pretty much zero about it. The sniffer which Nordic provides only sniffs BTLE and wireshark to my knowledge has no ANT protocol decoder on it either.

You could write your own ANT packet gatherer, spit the packets out of the UART and then write a wireshark decoder .. you'll be doing that a very long time if you start that project, there's a year of work there.

Hi Roland, thanks for sharing! I'm looking for a way to sniff ANT packages using wireshark on OS X. Do you have any tipps or hints for me?

cheers, Torsten
