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.

I did the OSX port of the receiving software 3-4 years ago. That's been available ever since, I still use it. I don't think Nordic has any plans to rewrite the sniffer software itself, so you're never going to get the kind of BTLE5 information you want that way.
