Android 无法使用蓝牙聊天示例连接到设备
我想创建应用程序，通过蓝牙连接到OBDII设备。首先，我想将我的应用程序建立在蓝牙聊天示例的基础上，然后开始构建自己的应用程序。我下载了蓝牙聊天示例。我试图连接到设备OBDII，但无法连接。我尝试连接到其他设备，如GPS蓝牙，它也失败了。来自play store的应用程序 蓝牙终端 连接到前面提到的这两个设备，没有任何问题。我可以和他们交谈并收到短信。我应该如何使用蓝牙示例才能工作 AndroidManifest.xmlAndroid 无法使用蓝牙聊天示例连接到设备,android,bluetooth,Android,Bluetooth,我想创建应用程序，通过蓝牙连接到OBDII设备。首先，我想将我的应用程序建立在蓝牙聊天示例的基础上，然后开始构建自己的应用程序。我下载了蓝牙聊天示例。我试图连接到设备OBDII，但无法连接。我尝试连接到其他设备，如GPS蓝牙，它也失败了。来自play store的应用程序 蓝牙终端 连接到前面提到的这两个设备，没有任何问题。我可以和他们交谈并收到短信。我应该如何使用蓝牙示例才能工作 AndroidManifest.xml <?xml version="1.0" encoding="UTF-
