Sniffing 802.15.4 with wireshark and MRF24J40 modules

Wireshark screenshot showing my test data

This is what I did the last two evenings or so. The data being sent is from my example app for my MRF24J40 module library, simrf.

The streaming into wireshark is all thanks to one of the Contiki devs, George Oikonomou’s sensniff project. The peripheral code is just another app using my library.

Neat! This should make some things a bit easier to understand as I move into getting the full networking stack working in Contiki. (You can ignore the warnings from wireshark about the packets being invalid 6LoWPAN frames, all the frames are just raw 802.15.4, with “abcd” being sent as the frame payload.
