No more restrictions as from now; with a few simple clicks you can run Paparazzi on the Bebop and have full autonomous flight and much more!
- Make sure you have the latest release version of Paparazzi installed.
- Power up your Bebop.
- Make a Wifi connection with your PC and the Bebop
- In the Paparazzi center choose "Bebop" in the airframe dropdown menu
- Press "Upload"
- Select the Bebop or ARdrone2 Flight in the session menu
- Press execute
Voila, you will get telemetry from the Bebop. Now it is up to you how and where to fly.

The Bebop has 4 Brushless motors, which are controlled by the cypress chip on I2C-1. This Cypress chip contains custom made firmware(BLDC) by Parrot, which can be automatically updated using a bootloader in the ESC part of the mainboard. The firmware from Parrot contains a nice closed loop RPM control, which is automatically tuned inside the factory.
For more information about how to communicate with the BLDC look at Bebop/BLDC. Or take a look at the "bebop" actuator inside the
- /usr/bin/dragon-prog Main program that controls the drone
- /bin/watchdog.sh Checks if Dragon is still running and reboots dragon
- BLDC_Test_Bench Controls the Brushless Motor Controllers for testing and playing sounds etc.
- bcmwl Everything with wifi
- diagnostic Outputs sensor diagnostic
- mk3_camera_eeprom Reads the front camera EEPROM
- config_mt9v117 Configure the bottom camera
For the Bebop you need to use a recent version GNU gcc-arm-linux-gnueabi (Ubuntu/Linaro 4.7.4-2ubuntu1) 4.7.4 provided with Ubuntu since 14.04 LTS.
the past you could also crosscompile with Sourcery CodeBench Lite 2012.03-57 for ARM GNU/Linux from
Greedy Mentor Graphics, previously called codesourcery. However the open'ness there is nowhere to be found anymore, so we'll say "No thanks" to Codesourcery ,now Greedy Mentor"
but if you insist , feel free restricted.
Load the video_rtp_stream.xml module. Receive the video stream with e.g. avplay:
$ avplay -loglevel quiet -max_delay 50 -fflags nobuffer rtp://192.168.42.1:5000
You can reset the Parrot Bebop Drone to factory settings. You will loose all your photos and movies recorded on your Bebop.
Steps: 1) switch the Parrot Bebop Drone on and press the on/off button for 10 seconds. 2) Wait... the LED will blink green and orange for a while, then lits up green. The Parrot Bebop Drone switches off automatically. 3) Done
