Android Development Kit (explicitly follow all of Google's installation instructions) NewSoftSerial library from Mikal Hart: Arduino Source code from this project (bluetooth_chat_LCD.pde attached below) Here's the full video instruction that we'll break out into steps: You can take the example sketch and change it however you want. Why? Just an easy way to test the Arduino's ability to not only receive messages from, but send messages to the Android phone. The Arduino message appears on the Android "Bluetooth Chat" sample app display. Every 30 seconds, the Arduino sends a message ("hello from Arduino") to the Android phone via Bluetooth.Ģ. Functionality: Arduino talks to Androidġ. The Arduino Uno prints the typed message on the LCD. Arduino Uno receives the typed message.Ĥ. Message travels through the air from the built-in Android Bluetooth modem to the Bluetooth modem connected to the Arduino Uno.ģ. The message you typed echoes on the app display.Ģ. Type a message in the app's text box and press the "send" button. Run the Android "Bluetooth Chat" sample app (after we modify the app in this instructable). Functionality: Android talks to Arduinoġ. Call setContactsSharingEnabled and set to trueĮnterpriseKnoxManager ekm = EnterpriseKnoxManager.getInstance(context) ĬontainerConfigurationPolicy ccp = kcm.This project slightly modifies the Google Android sample app called "Bluetooth Chat" so you can type a message in the Android app and that same message will appear on an LCD attached to an Arduino Uno.Get the GetContainerConfigurationPolicy from ekm.Create the EnterpriseKnoxManager object.There are 2 APIs to support this feature: For example, a device user can call a number from their contact list inside the container by sharing the number through a Bluetooth connection with their automobile’s hands-free phone system. This enhancement adds the ability to share contact information which is stored in the container. UUIDs.add(BluetoothUUID.A2DP_ADVAUDIODIST_UUID) īluetoothPolicy.addBluetoothUUIDsToBlackList(".*") īluetoothPolicy.addBluetoothUUIDsToWhiteList(UUIDs) īluetoothPolicy.activateBluetoothUUIDRestriction(true) Enable the "Share Contacts via Bluetooth" feature inside the container Allow use of Bluetooth only for calling and listening to music. You want to allow a trusted Bluetooth audio device using the device hardware ID. Only Bluetooth to only work for calling and listening to music. Add only trusted Bluetooth devices using hardware ID:īluetoothPolicy.addBluetoothDevicesToBlackList(".*") īluetoothPolicy.addBluetoothDevicesToWhiteList(AudioDeviceHardwareId) īluetoothPolicy.activateBluetoothDeviceRestriction(true) set activateBluetoothDeviceRestrictionto trueĮnterpriseDeviceManager edm = EnterpriseDeviceManager.getInstance(context) īluetoothPolicy bluetoothPolicy = edm.getBluetoothPolicy().Add the hardware IDs you stored in step 3 to the allowlist.Block all Bluetooth devices by using a * wild card and addBluetoothDevicestoBlackList.Add trusted Bluetooth devices using hardware ID.Create the EnterpriseDeviceManager object.isBluetoothEnabled() Only allow trusted hardware to work with Bluetooth. See the chart below for implementation logic.Ĭheck if Bluetooth is enabled. allowBLE to false, it also turns off regular Bluetooth functionality on the device. These APIs are dependent on each other, if you set. allowBLEprevents location accuracy from accessing the connection settings. This completely disables Bluetooth background services, even if triggered remotely.įor example, using. To disable Bluetooth background services, use. To prevent users from toggling Bluetooth on or off use. This topic describes how control Bluetooth using the Knox SDK.
