Program Icon
BTCall, BlueTooth device enabler for voice calls

Like most Android applications, BTCall must be installed from the Android Market. Installation steps do not differ from standard installation phases.
The full version is now available for purchase on the Android Market, the demo version will stop working on 31th December 2009. New features are planned for the full version.

DEMO version limits
The demo version has the following limits:
  • the service is not automatically restarted after phone reboot.
  • the service is stopped after 48hours, run BTCall again to restore service.

- Android 1.0
- Android 1.1
- Android 1.5
- Android 1.6

Please remember that direct BlueTooth control is not possible with current Android 1.x releases, so this software uses private methods to gain BlueTooth control.
Once started, the main activity screen reports your current BlueTooth device status; it can be:
- Enabled: your phone BlueTooth interface is enabled and working.
- Disabled: your phone BlueTooth interface is present, but it is powered off.
- Unknown: BTCall is unable to detect your BlueTooth device, so status cannot be determined: if you get this message, BTCall features will not be available at all.

To check BT device features, press the Menu button (screenshot 2), and tap on Status. BTCall will open a new dialog to show some informations about your BT device and current BT known devices paired/connected (screenshot 3,4).

To enable BTCall features, press the Menu button, and tap on Settings (screenshot 5).
In the Call settings category, you can define preferences related to current call; tap Call type to enable BTCall for:
- incoming only calls;
- all calls (incoming and outgoing);
Please note it is not currently possible to enable only outgoing calls.
You can define how long keep the BlueTooth interface powered with the Power off delay setting: when the call will end, the interface will be closed after a predefined time, to enable faster reconnections.
The Device Type preference screen allows you to select the device to use for phone calls: None to disable BTCall service at all, BlueTooth headset to control your BlueTooth device, Internal speaker to enable internal speaker.
The Time settings preference screen can be used to enable BTCall only for specific time ranges of the day; you can define up to 4 time zones, each one must specify start time and end time and which days of the week. If all time zones are disabled, BTCall will be enabled the whole day.
The Select Locale item allows to override current phone locale settings (for BTCall only) and select your preferred language for BTCall user interface. When selecting 'Default', BTCall will use your current phone settings to select the interface language.
The last setting item, Call control active, allows you to know current BTCall status: if enabled, it means BTCall has detected a phone call and enabled your BT interface; this means BTCall will power off the BT device at call end (and thus reset this flag). If you remove the flag, BTCall will not power off the BT device at end of current call. This does not change behaviour for future voice calls.

Known problems
  • To enable the BlueTooth interface, at least 5-10 seconds are required; then handset pairing and connection can require another 5-10 seconds interval. This time cannot be shortened, so you need to wait between 10 and 20 seconds (exact time depends on your devices).
  • It may happen that BT device seems to be on after call end: this is a problem with the notification bar, where the BT icon is still shown; if you look at Wireless Settings in your phone, you will notice that BT is marked off.

If BTCall cannot find your BT device, please contact support.
Enable BT in phone settings and open BTCall: BT status must be enabled, the Status dialog must report your BT device informations.
Disable BT in phone settings and open BTCall: BT status must be disabled, the Status dialog must tell you to enable the device.
Check if your handset connects automatically on phone calls without BTCall installed, or if BTCall installed, disable all preference settings.
