Screenshot:

• Crazyflie
• Crazyradio dongle
• USB On-the-go (OTG) cable (aka. USB Host cable) with Micro USB to USB
  • e.g. from Amazon
• Android device with Android version 4.0 (API Level 14) or higher
• Optional: PS3 controller (or compatible)

There is no official version in the Google Play Store yet, but you can download a compiled version from:
https://bitbucket.org/fredg02/crazyflie-android-client/downloads

1. Open the URL in your Android device's browser and download the newest APK
2. Make sure to “Allow installation of apps from sources other than the Play Store” (Settings → Security)
3. Install the APK (e.g. CrazyflieControl_2013-10-15.apk) from the browser's download folder
   • If this does not work, use a file manager like ASTRO File Manager to open the file.

1. Connect the Crazyradio dongle to the Android device with the USB OTG cable.
2. A pop-up should ask you which app you'd like to use with the USB device.
3. Select the Crazyflie app (“Crazyflie Control”).
4. When you run the app for the first time, you can scan for the Crazyflie (must be switched on). (Menu → Radio Scan)
   • Or you can set channel and data rate in the preferences manually (Menu → Preferences)
5. Once the channel and data rate is set, you can connect to it. (Menu → Connect)
   • The green LEDs on the Crazyflie and the Crazyradio should blink rapidly.
6. Use the on-screen controls to fly the Crazyflie.
   • WARNING: Be careful with the controls, they are harder to use than a gamepad.

Instead of using the on-screen controls, you can also connect an external controller like a PS3 Controller (or compatible):

In addition to the USB OTG cable, you'll also need:

• USB Y-Cable
• USB Hub
• PS3 Controller (or compatible joystick/gamepad)

Setup:

1. Connect a USB Host (OTG) adapter to your Android device
2. Connect a USB Y-cable with the USB Host adapter
3. Connect a wall-plug with the (red) power plug of the Y-cable (you need external power)
4. Connect the upstream port of a USB hub with the socket of the Y-cable
5. Plug the PS3 controller and the Crazyradio into the USB hub
6. The Crazyflie Android client should say “Using external PS3 controller” and the Crazyradio's LEDs should light up for a second
7. Press the “PS” button and move the analog sticks (the pitch/roll/thrust/yaw on-screen values should change)

Alternative setup without a USB Y-cable:

• Your Android device must be rooted
• Sixaxis Controller app

Setup:

• Flight data from the Crazyflie is not displayed
• Size of on-screen controls can not be changed
• Larger screen size of tablets is not used efficiently
• No reliable connection quality indicator
• Repeatedly connecting and disconnecting the Crazyradio can cause problems
