BLE 4.2 sniffer

[lbehhhh]

I am hoping to get solid verification that nordic offers a solution for sniffing BLE 4.2 packets.

The application I need to sniff is maxing out the MTU (250B payload) so I need support for long packets.

The blogs and googling haven't provided me with a solid answer.

Thanks

I'm in the very same situation. I have MTU sizes > 200 bytes and I'm blind to what happens over the air. In addition, I have the problem, that I'm using a Mac to work with. If I got the NRF Sniffer architecture right: There is a firmware on an evaluation board, sending the received data via a serial connection, which is then reformated by some python scripts, which send sends the data to wireshark for interpretation.

I would be happy to help to port the windows-only part to OS/X and to help to improve the eval board firmware, if Nordic want's to release this as open source.

I mean, yes, I could write a firmware for an eval board that does the same and write an adapter for wireshark, but this would likely take me some weeks and the NRF Sniffer is already there.

OK at some point I'll upgrade to the latest wireshark for it, I thought I was at least fairly current .. actually it's easier now as all the drivers are built in.

And I don't need to share the protocol documentation, nordic provides it in the package you download, they made that available about .. well 3 years ago. You just have to read it.
