Le croquis Controler
The Controller sketch allows you to turn your BLE-enabled iOS or Android device in a hand-held controller or an external data source, taking advantage of the wealth of sensors on your phone or tablet.
You can take accelerometer or quaternion data from your phone, and push it out to your Arduino via BLE, or get the latest GPS co-ordinates for your device without having to purchase (or power!) any external HW.
Ouvrir le croquis
Pour ouvrir le croquis ATCommand, cliquez sur le menu Fichiers > Exemples > Adafruit_BluefruitLE_nRF51 dans Arduino IDE puis sélectionnez controller:

Configuration
Vérifiez la page Configuration présenter plus tôt dans le tutoriel! Il est important de configurer le croquis pour utiliser soit l'UART Logiciel/Matériel, soit le bus SPI Logiciel/Matériel correspondant à votre plateforme. Par défaut, le croquis utilise le bus SPI matériel
Si vous utilisez le port série/UART logiciel ou matériel:
- Ce tutoriel ne requière pas l'utilisation de la broche MODE, assurez-vous d'avoir l'interrupteur en position CMD si vous ne configurer pas (et ne connectez pas) la broche MODE.
- N'oubliez pas de connecter la broche CTS sur la masse/GND du Bluefruit si vous n'utilisez pas le signal CTS! (Le Flora l'a déjà branché à la masse)
Exécuter le croquis
Once you upload the sketch to your board (via the arrow-shaped upload icon), and the upload process has finished, open up the Serial Monitor via Tools > Serial Monitor, and make sure that the baud rate in the lower right-hand corner is set to 115200:

To send keyboard data, type anything into the textbox at the top of the Serial Monitor and click the Send button.
Utiliser Bluefruit LE Connect en mode contrôleur
Once the sketch is running you can open Adafruit's Bluefruit LE Connect application (available for Android or iOS) and use the Controller application to interact with the sketch. (If you're new to Bluefruit LE Connect, have a look at our dedicated Bluefruit LE Connect learning guide (Adafruit, anglais).)
On the welcome screen, select the Adafruit Bluefruit LE device from the list of BLE devices in range:

Then from the activity list select Controller:

This will bring up a list of data points you can send from your phone or tablet to your Bluefruit LE module, by enabling or disabling the appropriate sensor(s).
Streamer les données de senseur
You can take Quaternion (absolute orientation), Accelerometer, Gyroscope, Magnetometer or GPS Location data from your phone and send it directly to your Arduino from the Controller activity.
By enabling the Accelerometer field, for example, you should see accelerometer data update in the app:

The data is parsed in the example sketch and output to the Serial Monitor as follows:
Accel 0.20 -0.51 -0.76 Accel 0.22 -0.50 -0.83 Accel 0.25 -0.51 -0.83 Accel 0.21 -0.47 -0.76 Accel 0.27 -0.48 -0.82

Note that even though we only print 2 decimal points, the values are received from the App as a full 4-byte floating point.
Le pavé de commande
You can also use the Control Pad Module to capture button presses and releases by selecting the appropriate menu item:

This will bring up the Control Pad panel, shown below:

Button presses and releases will all be logged to the Serial Monitor with the ID of the button used:
Button 8 pressed Button 8 released Button 3 pressed Button 3 released
Sélection de couleur
You can also send RGB color data via the Color Picker module, which presents the following color selection dialogue:

This will give you Hexadecimal color data in the following format:
RGB #A42FFF

You can combine the color picker and controller sample sketches to make color-configurable animations triggered by buttons in the mobile app-- very handy for wearables! Download this combined sample code (configured for Feather but easy to adapt to FLORA, BLE Micro, etc.) to get started:
