Again, I’ve not tried to drive packets beyound their GIU tool for the most simplistic, dumb testing.Īs you are on the LimeSDR forum I will assume that you are using a LimeSDR. They also have some open source to sniff the packets into WireShark. For example, TI sell a dongle dev kit with one of their older ships that you can use with their free RF Studio package to sniff and transmit packets. There are simpler ways into ZigBee/802.15.4. ZigBee is a networking layer ontop of 802.15.4 that, I personally, would impliment above GnuRadio using rftap to interface with my code.The IEEE spec describes this very well in the 2.4 GHzPHY appendix. This is all done for you with the PHY code. IEEE 802.15.4 is OQPSK with the data bits get spread in to chips with multiple values.As I am receive only, I am only using receive componnets of the 802.15.4 code base and only the lowest layers at that.I am not sure if the GR-802.15.4 package handle all of the compents needed to make a real system such as autmatic real-tome ACKs, etc. I’ve not looking into transmitting wiht rftap, but I assume that should work just fine.As far as I know WireShark is only logging traffic an there is no way to drive traffic from WireShark. Having WireShark loog traffic is very helpful to us. Indeed my code is receive only as I am using it to sniffing only to help debug another system.But if the demodulation is niche or new, you may have to create your own. My starting point would be to look through possible gnuradio recipes ( ) and etcetera ( ) to see if someone has done something that I could use to output maybe a UDP stream. And that demodulation will be totally different, depending on the protocol. So the piece you are missing is the demodulation of a raw IQ datastream into a format that Wireshark can analyse.

So before Wireshark can do anything you need a raw demodulated binary bitstream in a format that Wireshark can process.Ī LimeSDR captures RF signals and converts them into an IQ steam, which is still a modulated signal, or multiple modulated signals. Is it MPEG2 transport stream, or WiFi, or ZigBee, or something else ? The big bit that you left out is what protocol you want to try to process with Wireshark. Your question is missing a key piece of information.
