Subject: Re: [Discuss-gnuradio] Simulation with MAVLink protocol
Hi Paulo,
GNU Radio gives you but the framework to write and connect signal
processing blocks, as well as a nice set of "standard" blocks.
Among the functionalities available there are means to generate
packets and process the same.
If you know that if you can capture the signal, you could
mathematically/algorithmically analyze it, it's basically possible
to implement this in GNU Radio.
That being said, it's not really easy to implement a complete
packeted standard in GNU Radio since that might be a "logically"
complex task, involving different modulations, synchronization,
collision detection, arbitration, resend requests and much more.
However, there are several examples of people being able to decode
received signals. I like to point gr-ieee802-11 (WLAN packets
*transceiver*), and for a "simpler" system gr-air-modes (air traffic
control message decoding).
Greetings,
Marcus

Hello, I have some needs and I'd like to know if GnuRadio can help me with it. I have already read some material at GR website and I didn't get the answer.I need to receive and send packets with a specific protocol called MAVLink, used in mini UAVs. More specifically I am thinking about developing a sniffer.I don't have sdr hardware for now, then for starting I am thinking on simulation. My doubts are as follows:
- Is it possible to implement a new protocol for sending and receive packets? (MAVLink protocol)
- My idea is to simulate the exchange between a UAV and a control ground station. Would it possible to do it?
Thanks in advance.
