This tutorial explains how to set up unidirectional communication from the SDR to a normal WiFi card.
On the PC, put the card in monitor mode. In this mode, it will pick-up any frames without having to associate with a WiFi network. The easiest way to see if frames are received correctly is to use a tool for network monitoring like tcpdump, tshark, or Wireshark.
On the SDR, we use the
wifi_tx.grc flow graph from the example directory.
With the default setup the transmitter will sent periodic messages with a constant payload.
In addition, frames can be send by connecting to the UDP server listening on port 52001.
This can, for example, be done with netcat:
nc -u localhost 52001
You can even connect the SDR transceiver to the Linux TCP/IP stack using a Tun/Tap interface.
An example can be found in the
transceiver.grc flow graph.
The necessary configuration is shown in the
nic.sh script in the apps folder.
If it does not work out of the box you can try the following:
