Hi All ... Very first time posting here ... be gentle.

I've asked a similar question over on the Nordic Semi forums (, but wanted to get some additional "eyes" on the problem.

Trying to get the new(er) version of the Nordic nRF BLE Sniffer (v2) (written in python) working with a new(er) version of Wireshark on an OS X system. Specifics are: 2010 MacBook (4GB Ram) / Stock El Cap 10.11.6 / Wireshark 2.5.0 / Pyserial 3.4 / Python 2.7.10 / JLink 6.16c / Nordic Dongle (pca10031) with the correct firmware. Note that I have also tried 2.4.2, 2.4.5, and 2.4.6 ... all fail.

Long story short, when I install the Nordic nRF sniffer python files in the "extcap" directory, Wireshark will crash when I try to start a capture (NOT at startup / launch). If I remove the nRF sniffer files, Wireshark runs normally (i.e. when I start a capture on an ethernet port, it works correctly without crashing). I can post a crash report if necessary ... essentially it's showing a bus error (excbadaccess) to libobjc.A.dylib which seems to indicate that something associated with Wireshark is trying access something in memory that it shouldn't ... Anyone have any thoughts?

Note: Others with similar / identical setups have gotten the "system" to work ...

BR, Marshall
