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!
What you need
- A Bebop or Bebop 2 updated to at least firmware v3.3.0
- A joystick, for example this one
- A laptop with Ubuntu installed
Steps to follow:
- Install Paparazzi via the one liner to be found here. Just Cut 'n Paste (CTRL+C from webbrowser then CTRL+SHIFT+V in your Linux terminal) and press ENTER
- Start Paparazzi Center with the default configuration
- Power up your Bebop
- Press the on/off button four times short fast half a second clicks after the bebop is fully powerd up, notice the solid green light on Bebop and solid Red on Bebop 2
- Make a Wifi connection with your PC and the Bebop
- In the Paparazzi center choose "Bebop" Or "Bebop2" in the airframe dropdown menu
- Press the "Upload" button in the Paparazzi Center, wait...
- Select Flight UDP/Wifi in the session menu
- Press execute
Voila, you will get telemetry from your Bebop. Now it is up to you how and where to fly.
TIP: Good video series to watch. Although it is made for the ARDrone 2, the steps are very similar for the Bebop drone.

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. Since version 2 Parrot changed the order and rotation direction of the motors.
For more information about how to communicate with the BLDC look at Bebop/BLDC. Or take a look at the "bebop" actuator inside the
The original programs on the Bebop
- /usr/bin/dragon-prog Main program that controls the drone
- /bin/watchdog.sh Checks if Dragon is still running and reboots dragon-prog if it somehow would not be running anymore
- 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.
If you somehow need to compile kernel driver files to run on your Parrot Bebop, well, yes, you must use that exact compiler...
Tips & Tricks
Make sure the video_rtp_stream.xml module enabled in the airframe. Receive a video stream with e.g. avplay, vlc or a python app:
$ avplay -loglevel quiet -max_delay 50 -fflags nobuffer rtp://192.168.42.1:5000
$ vlc ~/paparazzi/var/sdp_tmp/192.168.42.1/stream.sdp
You can reset the Parrot Bebop Drone to factory settings. You will loose all your photos and movies recorded on your Bebop. To do this you need to press and hold the power button for 10 seconds. The LED will blink green and orange for a while, then green and the drone will shutdown.
Theoretically is is not important which firmware you use for Paparazzi to fly. But with the latest firware we get better Video imagery. So if you can.. use the latest firmware.
The Paparazzi volunteers test flew the Bebop with Firmware v1.98.11 and v2.0.57, v3.0, v3.2, v3.3, v3.9, v4.0.6
Note that under v4.0.x the hardware accelerated extra nifty features for the front cam don't work (yet..) nOne could use the original encoder from the v3.9 firmware if wanted. So if you need hardware assisted compressed video imagery and have a Bebop 2 do not update to v4.x just yet. Or better fix the camera not working issue...
The v4.0.6 is the latest firmware version know as of 20170610 for Bebop 1. For bebop 2 Latest know is v4.7.x If even newer firmware is available please report any (if any) issues found related to the firmware on e.g. the mailinglist.
The original Bebop2 damper are very soft and can cause oscillations around roll. You can print harder dampers from Thingiverse yourself that will degrade the video quality but remove these oscillations. Use the _nodamp airframe files in that case.
Serial bidirectional teminal access
This is handy if one e.g want to dump and set the build in GPS with software like uCenter on a PC. uCenter also run under Wine.
su root -c "getty -n -L -l /bin/su 115200 /dev/console" &
On the Drone side, access via telnet. the IP is the IP addres you got from the Bebop on your local PC , do this:
nc 192.168.42.4 12345 </dev/ttyPA1 >/dev/ttyPA1
Using the MicroUSB for serial data
The Bebop, as wel as Disco has this tiny micro USB connector. This USB connector can also be used with help of a USB to Serial conversion board. To use the driver in current firmware OTG serving should be off. Take a look here for more information, photos, connection examples, sourcode and real life example of how to use this port.
