Building for cube:evk

The cube:evk from cubesys - an nfiniity company 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 cube: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 cube: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 cube:evk. The V2X radio on the cube: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 cube: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 cube:evk from remote.

Building and Running Socktap on the cube:evk

You can also build and run socktap on the cube: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 cube:evk for positioning data
cube> ./bin/socktap -l cube-evk -p gpsd --gpsd-host 127.0.0.1
