- Connect two long antennas (silver extendable, one in each toolbox, two for each team), one of them to RTL-SDR, and another one to the Tx port of Adalm Pluto. (The short antenna that came with Adalm is not suitable for this task.)
- Place the Tx and Rx around 1 .5 meters meter away.
- Run tx.grc and rx.grc, or stlsdr.grc.
- Make sure the "Enable Interference" checkbox at tx is unchecked.
- If everything is correct, you should be able to observe outputs at the console window (either the GNURadio or Python console.) There are two possible observations:
- Msg followed by Packet Count, Text Count, PSR, and Time. (Signifies that the receiver is able to receive and demodulate the message correctly, see example below.)
- "OOOOOOOOOOOOOOOOOOOOOOOOOOOOO". (Signifies that the receiver is receiving things but unable to demodulate the message expected, an overflow situation.)
- To fix the second scenario, double-check all the settings, and move Tx and Rx closer. Ask for help if you are unable to make it work.
