Connecting to other Bluetooth Device by BeeTee app

I need to implement a self bluetooth app to connect with all bluetooth devices to iPhone. I know it is not possible with CoreBluetooth framework. I use private API and added header files of DeviceManager and BluetoothManager to private frameworks and downloaded BeeTee Project from here This app runs and finds all bluetooth device near me but when I have tried to connect to a device by this code: [self.bluetoothManager connectDevice:bluetoothDevice]; and this [bluetoothDevice connect]; When a cell is selected, Both of above codes request to connect but BTM returns this message: BeeTee[5473:60b]

如何启用 Lollipop 中引入的新蓝牙 A2DP 接收器功能?(How can I enable the new Bluetooth A2DP Sink feature introduced in Lollipop?)

问题 我正在尝试修改 Nexus 5 的 AOSP android 映像以包含对蓝牙 A2DP 接收器的支持。 我发现 Google 非常好,可以为 Nexus 5 包含一个隐藏的构建目标。 https://android.googlesource.com/device/lge/hammerhead/+/android-5.0.1_r1/car_hammerhead.mk 这包括修改后的 Bluedroid 配置文件,允许设备通过蓝牙通告 A2DP 接收器服务。 它还将设备类别更改为蓝牙自动 Carkit,并修改 Bluetooth.apk 的配置以支持 A2DP Sink 和 AVRCP 控制服务。 这让我完成了大约 75% 的工作。 我通过抓取 KitKat 手机并与 Nexus 5 上的修改版本配对进行了大量测试。它正确地宣传了 A2DP 接收器服务并允许我的 KitKat 手机连接到 A2DP 接收器服务。 在 KitKat 手机上,它似乎甚至允许我将音乐流式传输到 Nexus 5。但在 Nexus 5 上从来没有听过音乐。我什至在 Nexus 5 上捕获了 HCI 流量,发现音乐实际上正在流式传输到电话。 问题是蓝牙设备接收音频流,但音频从未路由到扬声器。 有谁知道我如何将 A2DP 流路由到 Nexus 5 的扬声器?

Symbol.WPAN.Bluetooth example that transfers data

I am trying to use Symbol.WPAN.Bluetooth that comes with the EMDK for Symbol devices. Does anyone happen to have a working example that transfers data? Symbol's example just pairs the devices. (They apparently think that transfering data is not really needed in a Personal Area network example.) Anyway, I know this is a long shot, but if anyone has gotten this to work I would love to see some code. This is what I have tried. I have one device press button1 and another device press button2. The read value is always a zero length byte array. using System.Text; using System.Windows.Forms; using

Getting wrong serial-port names from bluetoothdevice (c#)

To get all avaliable Serialports from the system i use the following command. SerialPort.GetPortNames It works fine for the mainboard serial port, but with the bluetooth device i get the wrong portnames. For Example: Instead of COM7 i get sometimes COM70 or COM7ö. Its always 1 letter to much. any suggestens? PS: I am using newest Visual Studio Express in Windows 7 PPS: The dirty hack to cut the last letter didn't work because i don't know which one is the bluetooth serial port (with various bluetoothstick or devices it changes the number of the comport) and after trying various sticks i

What is the maximum number of bonded i.e. 'Paired Devices' for Bluetooth LE devices in Android?

The information being sought with this question is I think similar (but not the same) as the information sought here... "How many devices we can pair via Bluetooth of BLE to Android?" ...and so let's re-ask it a different way: Let's say we have a use case where someone with a mobile phone may want to connect securely (using industry standard security mechanisms) to a Bluetooth LE device using Pairing. When Pairing occurs, bonding information is stored in the mobile phones - - > Settings - - > Wireless - -> Bluetooth - - > Paired Devices window (dialog). These 'Paired Devices' will remain

How do I pair and/or bond to BLE on iOS using Swift code and an HM-10 so data sent is encrypted?

Background I've built a simple circuit which includes an Arduino Nano and a HM-10 BLE serial module. You can see that circuit at the following Electrical Engineering SE question: https://electronics.stackexchange.com/questions/412525/when-i-write-data-to-a-ble-characteristic-ffe1-to-send-data-over-bluetooth-is I also have an Xcode project written in Swift that successfully sends bytes to the FFE1 characteristic. It all works great and I can see the data coming from my iPad via Arduino Serial monitor. However, from the research I did (see previous link) I believe I've determined that the data I

Setting up 32feet library

I'm trying to get started with this library: 32feet I have a Broadcomm Bluetooth Stack and haven't been able to figure out how to get this library set up. When I run my code, I get: Unhandled Exception: System.PlatformNotSupportedException: No supported Bluetooth protocol stack found. After digging around on their site, I found this: Installation instructions It says to copy the appropriate DLL's into the project and then run the Test32FeetWidcommWin32.exe. I've tried putting the files in every single folder in my Visual Studio project and then running that EXE, but I still get the same error

SensorTag 2 CC2650 advertising indefinately firmware

I want to use a SensorTag 2 so that it is sitting there broadcasting it's data (and, critically connectable over bluetooth) from when it's turned on to when\if I ever turn it off. Out of the box, the tag is set to only advertise over Bluetooth for a few mins which means that when the connection eventually fails or when the device connected to the tag boots etc etc you can't connect again without physically visiting the tag and resetting it. I see there is firmware that the myWeatherCenter people have created that lets the tag work as a weather station by basically setting it to advertise

android bluetooth implementation basics

can anyone in simple words explain me the need of UUID in android bluetooth example. I have read some articles about it but it is still not getting clear the exact need of UUID. And now let me explain you the scenario of what I want to develop: I want to develop an android application to transfer data for example a "FILE with .xyz extension" from my phone to the other phone over bluetooth. IT IS NOT AT ALL NECESSARY THAT THE RECEIVING PHONE SHOULD ALSO HAVE THE APPLICATION THAT I AM USING. I just want to transfer data from my application to other phone and thats it. I don't care what the
