Documentation for the bebop-bridge application

1. Setting up your RaspberryPi
2. Configure your network
3. Install Docker
4. Install and run Bebop-Bridge

Open Shell in Docker Container

sudo docker exec -i -t bridge-service  /bin/bash

Debug network traffic between Bebop and service

To see back and forth traffice from port to port:

tcpdump -i wlan1 

Send test package (once)

Send udp message to 192.168.0.199 43210

echo -n “foo my message goes here” | nc -4u -w1 192.168.0.199 43210

Send tcp message to 192.168.0.199 4000

echo -n “foo my message goes here” | nc -4 -w1 192.168.0.199 4000

Windows

Use http://eternallybored.org/misc/netcat/

Listen to traffice in a running Docker container:

Need to install some stuff:

docker exec bridge-service apt-get update
docker exec bridge-service apt-get --assume-yes install netcat // for nc
docker exec bridge-service apt-get --assume-yes install net-tools // for ifconfig
or
docker exec bridge-service apt-get --assume-yes install tcpdump // for tcpdump

Listen to all traffic:

docker exec bridge-service tcpdump -i eth0

Listen to traffic via port 4000 (socket.io connection of controller)

docker exec bridge-service tcpdump -i eth0 -n tcp dst port 4000

Listen to udp traffice on 43210

docker exec bridge-service tcpdump -i eth0 -n udp dst port 43210

Listen on Linux to traffic

Listen to udp messages from Bebop when connected with wlan1 to Bebop network

sudo tcpdump -i wlan1 -n udp dst port 43210

Listen on Windows with Wireshark

Listen to messages from Bebop when connected with interface 1 to Bebop network. (Check with wininfo32 -> Components -> Network for interface index.)

In Wireshark: use filter: udp, or filter: udp port 43210, or tcp port 4000
