I couldn't use WiFi for problems of signal range, for this reason I opted to connect 2 stations with a Wireless Serial Connection by a cheap <a href=„http://ardupilot.org/copter/docs/common-3dr-radio-advanced-configuration-and-technical-information.html“>SiK Telemetry Radio V2 433Mhz</a> (20$).<p>To create a Peer to Peer TCP/IP connection I used SLIP (Serial Line Internet Protocol).<br/></p><h4> Server-Side:</h4> - Connect a USB Telemetry Radio, with dmesg we check the serial port name<br/>   $ dmesg | grep now attached<br/> - Load a SLIP module<br/>   $ sudo modprobe slip<br/> - Install net-tools for slattach tool<br/>   $ sudo apt install net-tools<br/> - Configure SLIP and attach to a serial port<br/>   $ sudo slattach -L -s 57600 -p slip /dev/####Serial_Port_Name<br/> - On another console create a network interface<br/>    $ sudo ifconfig sl0 192.168.5.1 dstaddr 192.168.5.2<br/> - [OPT] Sharing internet connection, <a href=„https://help.ubuntu.com/community/Internet/ConnectionSharing“>follow this link</a>.<br/><h4> On Raspberry Pi Zero:</h4> - Connect a Telemetry Radio on Raspberry Pi Zero <a href=„https://it.pinout.xyz/pinout/serial_pi_zero“>Board</a><br/> - Load a SLIP module<br/>   $ sudo modprobe slip<br/> - Configure SLIP and attach to a serial port<br/>   $ sudo slattach -L -s 57600 -p slip /dev/ttyAMA0<br/> - On another console create a network interface<br/>    $ sudo ifconfig sl0 192.168.5.2 dstaddr 192.168.5.1<br/> - Test TCP/IP connection<br/>   $ ping 192.168.5.1<br/><h4> Simple test Video with 2 Ubuntu Machine:</h4> <br/><iframe allowfullscreen=„“ frameborder=„0“ height=„210“ src=„https://www.youtube.com/embed/rR9ixE3_h0A?ecver=1“ width=„280“>[embedded content]</iframe>
