In the previous post we learned regarding the internal circuitry of a typical Bluetooth headset, in this post we'll see how a Bluetooth headset unit can be modified or "hacked" in order to make it work for other personalized applications.
在上一篇文章中我们学会了how to break open a Bluetooth headset device还研究了内部包含的各种组件。
识别说话者和麦克风
尽管大多数耳机内应用的阶段ear to be too sophisticated to digest, the two elements which are still quite traditional are: the speaker and the mic, and those are exactly what we are interested in for implementing the proposed hacking procedures, because these two ports basically become the input and the output terminals of the device.
确切地说，扬声器输出更有用，可以假定以推拉格式生成模拟音频频率。该模拟信号可以轻松地翻译并转换为逻辑信号，用于操作转换设备（例如继电器）。
In the following couple of images we are able to see the speaker wires which could be simply cut and striped at the ends for accessing the processed analogue frequencies for the required modifications.
与桥梁整流器网络集成
一旦制定了上述操作，这一切都是关于将电线与桥网络集成，然后是光耦合器阶段，如下所示：
The bridge network converts the differential output response from the Bluetooth speaker outputs into a full wave DC, which is further filtered by the 100uF capacitor to produce a clean DC across the opto input.
The DC is converted into a logical content across the collector/ground of the opto transistor. This output may be configured with any standard flip flop circuit for toggling any desired load.
The above toggling could be initiated by activating the Bluetooth headset with a data from a cell phone or any similar compatible device. Each time the speaker responds, the info gets translated into the above discussed toggling effect over a connected relay.
翻板拖载电路
A flip flop circuit can be seen in the following figure which could be integrated with the above opto output for obtaining the intended relay operations.
Parts List
r3 = 10k，
R4，R5 = 2M2，
R6, R7 = 39K,
R4，R5 = 0.22，光盘，
C6 = 100µF/25V,
D4，D5 = 1N4148，
T1 = BC 547，
ic = 4093，
The above method explains an easy way of hacking a Bluetooth headset for remotely operating a particular appliance, in the next post (yet to be published) we'll learn how to hack a Bluetooth Headset as a wireless home theater system.
Sir… great … waiting for next
谢谢月光！我会尽快发布。
哇 ！伟大的产品
you are most welcome
WAITING FOR NEXT POST
thanks for reminding, I'll try to post it soon…
SIR I AM WAITING FOR YOUR NEXT POST. WHEN WILL IT COME. I AM EAGER TO BUILT IT
Arif，实际上并不困难，您只需要购买便宜的家庭影院系统，并将蓝牙耳机的扬声器线与家庭影院的耳机插孔连接起来……。它将开始像蓝牙控制的家庭影院系统一样开始工作…。任何音乐都可以通过蓝牙无线播放
wow,,,,,,thanks so much swagatam………….just like others am really waiting and working for the next.
感谢Swagatam Am等待下一个工作，
Hi Swagatam,please help me with a circuit design on how to connect ICL7107 with 2 digit 7 Segment display.Thanks
感谢Vincent，但是我很遗憾地这样说，我不知道如何使用上述A/D IC配置2位数的显示。
出色的指南给我想法。光纤链接可以代替光纤链接，该光纤链接可用于仅在BT范围和/或视线之外的受控设备。相反，第四扇门可以看一下N2的引脚4，并在BT端可见一个状态指示剂。看，我想用一个较旧的Android平板电脑来控制多个远程锁，它可以一次处理五个BT连接。
您是否知道有任何删除BT功能的骇客，并且仅将其余的耳机用作与BT无关的其他项目的独立可充电微型电源？
Thanks very much!!
Sorry, but without the BT function the unit would have no other purpose, could you please explain how do you visualize the unit to serve the mentioned purpose with the BT discarded??
What I meant was, to utilize just the battery and associated charging circuitry within your average BT headset to power small devices that don't need to communicate over BT.
当（不是很好的）电影出现以找到一种可充电的东西来代替电池时，我问了一个朋友，他买了一个昂贵的绿灯灯戒指“玩具”。我注意到，我打开的BT耳机里面有一个空间，可以在BT耳机上查看内部的内容，以及在戒指外部隐藏USB充电端口的空间。不幸的是，电路板有点太大而无法合身，但是我无法弄清楚我可以切断哪些位，而无需禁用充电电路。我很幸运，找到了一个合适的微小充电，但仍然需要删除才能充电 - 我想在每次电池需要充电时都没有拆卸和重新组装。
Since then I've thought of several other ways that could be useful, but the chips in BT sets are hard to find data on- Google is spectacularly unhelpful. I was hoping that you might know of a website that collects that sort of information in one place.
OK understood, in that case you could probably try the second circuit from the following article:
//www.addme-blog.com/2013/12/usb-automatic-li-ion-battery-charger.html
you could try SMD parts for making the unit truly compact.
上面的电路是由我设计的…。但是我不知道BT模块中使用的芯片
请先生can i use the Bluetooth hand set to replace the cod-less door bell light control system?
是的，您可以使用它...
Sir can you give me some flow code v5 examples
伟大的…swagatam先生。
下一篇文章，我希望您在插入每个头盔中插入的摩托车手上的通信攻击蓝牙
Thanks Ansar, I’ll try to update it soon. I assume it is for left/right turn signalling and brake lights?
