Multiple Parrot Drones as Swarm via WiFi Router

About

If you are eager to try and fly multiple Bebop or Discos at the same time and communicate to each-other, this is the page to read on how to get that to work

What your need

• 2x Bebop
• 1x Router
• Your Fieldlaptop

Network

First all your Bebops need to be configured. Repeat for all your Bebops

There is a configuration to make. Here are some examples as a start:

cd ~/paparazzi/sw/tools/parrot

./bebop.py configure_network YOURROUTERSSID managed dhcp

./bebop.py wifikey none none

or if you have WPA2 and fixed IP's and do not have set the MAC of your Bebop in your DHCP for a static lease. IP is an example, your router could be on a different subnet. Ofcourse change the YOURROUTERSSID and YOURKEY to the SSID of your router end the password of your network.

cd ~/paparazzi/sw/tools/parrot

./bebop.py configure_network YOURROUTERSSID managed 192.168.1.44

./bebop.py wifikey wpa2 YOURKEY

IVY Bus

~/paparazzi/sw/ground_segment/tmtc/link -udp -udp_broadcast

Airframe

In Paparazzi-center make four (4x) an airframe configuration, you can use the same airframe file for all since AC_ID makes the difference

To be able to cross-communicate via UDP a additional setting to the Bebop airframe file needs to be added:

If your router has e.g. IP 192.168.209.1 then add this to your airframe in the target section:

 <configure name="HOST" value="192.168.209.$(AC_ID)"/>
 <configure name="MODEM_HOST" value="192.168.209.255"/>
 <configure name="MODEM_BROADCAST" value="TRUE"/>

Change the IP number according to your setup

Tips

• To make things manageable, one could also resort to local name resolving where the last part name of the device is the aircraft ID.
• Or set the last part of a static IP number to the Aircraft ID of your airframes

TIPS

Press and hold the Powerbutton for 10seconds in a row until the light turns red, that is a factory reset.
