====== Bluetooth Phone ======

====== Under Construction ======

===== Summary  =====


This application BlueZ/Ofono provides voice call from paired Bluetooth phone. 

The application uses following APIs:
  * Phone library: This class provides methods to operate with contacts and call history
  * tizen.bt as replacement of tizen.bluetooth %%API%% due to conflicts in underlying framework. The following Bluetooth functionalities are provided via Tizen Bluetooth %%API%%:
    * Controls local Bluetooth device, that is, turn Bluetooth on/off, etc.
    * Sets visibility
    * Discovers nearby Bluetooth devices (Device discovery).
    * Gets bonded devices information.
    * Controls bonding.
    * Connects to a service on a remote device and exchanges data.
    * Registers a service (RFCOMM) on a local device, which can be consumed by remote devices to exchange data.

The application supports multiple connected devices, however only one of the devices can be selected at the time. Selection is done from Bluetooth UI. In case that phone has active call additional Carousel element is replaced by CallDuration element.

  * Display call history
  * Display contact list

===== What the app does  =====


Features for Bluetooth include the following:
  * Viewing available devices in range
  * Pairing with a device
  * Displaying the status of various devices
  * Selecting the device once permissions have been exchanged
  * Downloading information such as contacts from the device
  * Allowing interactivity between devices interchangeably

Features for Phone include the following:
  * Making and receiving calls either manually or through the contact list
  * Viewing recent calls made on either of the devices
  * Viewing contacts

To launch the Phone application the user touches the phone icon at the top of the device (handset shape), or it can be launched through the Application Screen. If the Bluetooth connection has not yet been established, it will display the text “NO BT DEVICE SELECTED”. 

{{:wiki:wiki:?300}}

The user needs to visit the Bluetooth Settings Screen in order to establish a connection between devices before the features for the Phone application are available. To do this, the user can go to the Settings Screen by touching the settings icon at the top right on the Home Screen or Phone application,  or by going through the Applications Screen and touching the settings icon. Once in the Settings Screen, the user touches the word BLUETOOTH and the Bluetooth Settings Screen opens.

{{:wiki:wiki:?300}}  {{ :wiki:wiki:?300|}}

If Bluetooth is not yet turned on, the user taps the TURN ON button to scan for nearby devices. A list of devices that can be connected show up, each with a PAIR button next to it. Previously paired devices would also show up on the screen, with the option to UNPAIR. 

{{:wiki:wiki:?300|}}  {{ :wiki:wiki:?300|}}

The user taps the PAIR button. The mobile device being paired must now be checked, to see if the Bluetooth request for pairing permission has been sent. Respond affirmatively and the Bluetooth Settings screen will show that the selection is occurring.

{{:wiki:wiki:?200|}}  {{ :wiki:wiki:?200|}}

When devices have been paired the Bluetooth application should also request permission to access the mobile device’s phonebook. If not, the user must check the mobile device’s settings to make sure the profile for a phone connection is enabled. 

Once the final permission has been given, the application shows confirmation that the mobile device is 
  * Paired,
  * Selected,
  * What type of device it is,
  * Connected,
  * And an option to UNPAIR will be available.

The user can go now go back to the Phone application by using the BACK button or tapping the X at the top right corner of the screen to close the Settings Screen from the Phone application.

Now that the mobile device is paired and enabled within the Bluetooth settings, the phone application is able to place calls, handle incoming calls, display a call history, and display a contact list. The phone application screen will show recent calls under the telephone keypad. Use single finger scroll to go through the carousel list for the phone numbers and possibly see a thumbnail image of the caller

{{:wiki:wiki:?300|}}  {{ :wiki:wiki:?300|}}

By tapping the Contacts List icon (the A-Z flag in the upper right) the contact list is viewable. 
The list can be viewed in either list or icon view by tapping the grid icon or line icon to the left.

{{:wiki:wiki:?300|}}  {{ :wiki:wiki:?300|}}

To see the details for a contact, tap the contact row or icon. Then the screen shows the details for that particular contact. Tap the phone number to initiate a call.

The keypad screen displays the caller with thumbnail, and will display the status DIALING. 
Once answered, the screen indicates the call duration in addition to showing the options for the features SPEAKER, MUTE, HOLD, and ADD CALL.
Tap the red button to terminate the call. 

{{:wiki:wiki:?300|}}

To receive a call via Bluetooth, which is to the mobile device, simply tap the green panel.
To dismiss a call, just tap the red panel, or the user can also interact with the connected device.
The user may exit the Phone App at any time using the return arrow. If using another application, the Phone App will interrupt with the incoming call screen (see just above) and give the user the option to receive or reject the call.


===== Known Bugs  =====


  * Selecting previously discovered/cached phones will crash the widget.
  * Unpairing from the HU crashes the widget. You can restart it, but as long as you're shown as paired on the phone, you will not be able to re-pair again.
  * Performing a Scan from the widget does not find currently paired/selected phone.
  * There's currently no way to make the system "forget" a phone. This is especially a problem after unpairing through the phone's UI. (restarting will fix the issue)
  * After fully syncing with a phone, backing out of the Phone widget will disable/break the phone icon in the Home Screen. (though the Phone widget IS running in the background.)
  * Turn Off button seems to have no effect sometimes. (kill/restart widget will fix the issue)
  * If you stop a Scan, sometimes you will not be able to rescan from within the widget. (kill/restart widget will fix the issue)
  * Once Bluetooth has been Turned Off, Turning it back On again seems to turn it on, yet will not allow you to Scan. (kill/restart widget will fix the issue)
  * Widget initiates ActiveCall/Hangup messages in the background for no apparent reason.
  * Sometimes the phone will be automatically marked as Selected even after a fresh pairing. This will not allow you to select the phone and therefore will not sync contacts/call history. (widget issue likely)
