- change the CMake option **BUILD_SOCKTAP** to **ON** in CMakeLists.txt
- some bugs in security.cpp ...

- **ca** sends Cooperative Awareness Messages (CAM)
- Data format follows ITS facilities layer protocol that operates the CAM transmission
- **hello** sends simple BTP-B message with the binary payload 0xc0ffee

### TODO

- Applying a real GPS device in Vanetza.
