There are two integration points:</p><p><ul><li>UART driver</li><li>Bluetooth Power On / Off</li></ul></p><a name="androidBluetoothPortingDriver"></a><h3>UART Driver</h3><p>The BlueZ kernel sub-system attaches to your hardware-specific UART driver using the <code>hciattach</code> daemon.</p><p>For example, for MSM7201A, this is <code>drivers/serial/msm_serial.c</code>. You may also need to edit command line options to <code>hciattach</code> via <code>init.rc</code>.</p><a name="androidBluetoothPortingPowerOnOff"></a><h3>Bluetooth Power On / Off</h3><p>The method for powering on and off your bluetooth chip varies from Android V 1.0 to post 1.0.</p><p><ul><li><b>1.0</b>: Android framework writes a 0 or 1 to <code>/sys/modules/board_[PLATFORM]/parameters/bluetooth_power_on</code>.</li><li><b>Post 1.0</b>: Android framework uses the linux <code>rfkill</code> API. See <code>arch/arm/mach-msm/board-trout-rfkill.c</code> for an example.</li></ul></p><a name="androidBluetoothTools"></a><h2>Tools</h2><p>BlueZ provides a rich set of command line tools for debugging and interacting with the Bluetooth sub-system, including:</p><p><ul><li><code>hciconfig</code></li><li><code>hcitool</code></li><li><code>hcidump</code></li><li><code>sdptool</code></li><li><code>dbus-send</code></li><li><code>dbus-monitor</code></li></ul></p><p><span class="lh2"><a name="androidFooter"></a></span> </div> </div> <!-- end gc-pagecontent --> </div> <!-- end gooey wrapper --> </div> <!-- end codesearchresults --> <div id="gc-footer" dir="ltr"> <div class="text"> ©2008 Google<!-- - <a href="/">Code Home</a> - <a href="http://www.google.com/accounts/TOS">Site Terms of Service</a> - <a href="http://www.google.com/privacy.html">Privacy Policy</a> - <a href="/more">Site Directory</a> --></div> </div> <!-- end gc-footer --></div><!-- end gc-containter --><script src="http://www.google-analytics.com/ga.js" type="text/javascript"></script><script type="text/javascript"> try { var pageTracker = _gat._getTracker("UA-18071-1"); pageTracker._setAllowAnchor(true); pageTracker._initData(); pageTracker._trackPageview(); } catch(e) {}</script><div id="jd-build-id"> v0.6 - 25 November 2008</div></div></div></div></body></html>?? 快捷鍵說明
