Building for CUBE EVK

The CUBE EVK from nfiniity fully supports the Vanetza stack and its socktap application. An integrated V2X module listens for requests whether from a local or remote application. The communication protocol between host and V2X module is covered in Google’s Protobuf that is used in the respective link-layer implementation.

Configuration

Before building and running socktap you need to configure the V2X module and the WiFi once.

V2X Radio Configuration - C-V2X or DSRC

First of all select your desired radio configuration using the v2xconfig tool on the EVK:

# start dsrc or cv2x and enable auto-start
cube> v2xconfig start enable dsrc

Connect to your local WiFi

This is only needed for the wireless remote radio mode.

cube> sudo nmcli dev wifi connect '<ssid>' password '<password>'
# get your ip
cube> ip a

Building and Running Socktap for Wireless Remote Radio Mode

You can build and run socktap directly on your personal computer (host) and select cube-evk as link-layer. Further, gpsd daemon is running on the EVK that can feed socktap with GNSS data.

In wireless remote radio mode you develop, debug and run Vanetza/socktap on your personal computer. There is no need to flash or transfer the application onto your EVK. The V2X radio on the EVK listens for incoming requests from remote. Both devices need to be pingable from each other only.

host> mkdir build && cd build
host> cmake -DBUILD_SOCKTAP=ON -DSOCKTAP_WITH_CUBE_EVK=ON ..

# use fix position data
host> ./bin/socktap -l cube-evk -p static --cube-ip <cube-ip>

# use the ublox module on the EVK for positioning data
host> ./bin/socktap -l cube-evk -p gpsd --gpsd-host <cube-ip> --cube-ip <cube-ip>

Moreover, the integrated LTE module allows the user to do field tests with the EVK from remote.

Building and Running Socktap on the EVK

You can also build and run socktap on the EVK itself and it will connect to the local V2X module.

cube> mkdir build && cd build
cube> cmake -DBUILD_SOCKTAP=ON -DSOCKTAP_WITH_CUBE_EVK=ON ..

# use fix position data
cube> ./bin/socktap -l cube-evk -p static

# use the ublox module on the EVK for positioning data
cube> ./bin/socktap -l cube-evk -p gpsd --gpsd-host 127.0.0.1
