hcxbtdumptool

Small tool to capture packets from Bluetooth devices.

Initial commit - no Bluetooth functions - only help and version menue and Bluetooth device information available.

This is a playground to get some knowledge about coding Bluetooth.

Everything is high experimental.

Similar to hcxdumptool (WiFi) we use ioctl() system calls to control the device.

Brief description

Stand-alone binaries - designed to run on Raspberry Pi's with installed Arch Linux. It may work on other Linux systems (notebooks, desktops) and distributions, too.
