Hi Julián, interesting! I think I might be misunderstanding what's happening here, so I think we should make a sketch of what I think you're doing:
"data" --> Ground control station --> TX Antenna --> Air --> RX Antenna UAVdevboard Is that correct? Greetings, Marcus On 29.10.2014 15:43, Julián Andrés Quenardelle wrote: > Hey there!
