cd build
cmake ..

Supported features

• Proxy packets between MD and HU
• Save packets into pcap file
• Wireshark's extcap support
• ImGUI Analyzer

Supported platforms

• Windows
• Linux

Supported transports

• TCP via ADB
• Direct TCP connection (wireless)
• USB AOA

Known limitations

• Current TCP via ADB transport needs some improvements in packet reading. In some occassions, where are there big payloads (1080p HU resolution), sometimes only half of packet is read and proxy don't handle this situation. 720p works well.

How it works
