微信蓝牙配置-如何使用-有什么中文资料面包板社区

写在前面，最近公司在开发一款蓝牙设备，在这里我就和大家分享一下如何在微信配置蓝牙设备。参考资料 http://blog.csdn.net/skdev/article/details/50974343 http://blog.csdn.net/sadshen/article/details/47761801 http://blog.csdn.net/feilusia/article/details/48917625 测试APP 微信蓝牙协议调试工具AirSyncDebugger 这里可以下载https://blog.csdn.net/skdev/article/details/50974343 1. 首先我们看一下流程 BLE设备要发出符合格式的广播包微信扫到BLE设备发出的广播包，如果广播包符合微信配置的设备要求，则微信会请求建立与BLE设备的连接，连接建立后，通过读Indicate Descriptor确认Indicate Characteristic是否有Indicate属性，有的话会往Indicate Descriptor写值，BLE设备收到Deiscriptor写操作后，通过Indicate Characteristic往微信发Auth请求，微信通过Write Characteristic回应Auth请求，BLE设备收到Auth回应合，接着发Init请求，微信则回应Init请求，至此，连接就建立了，后面就可以不分先后往对方发数据了 2.AirSyncDebugger的日志，完整流程 *****************BLE： TwoWinter****************** ***** onTestBroadcastRecord ***** result = true, Has 0xfee7 or standard service in broadcast record 广播包：02 01 06 03 02 E7 FE 09 FF 0D 00 90 59 AF 0E 62 88 （这几个是mac) 0A 09 54 77 6F 57 69 6E 74 65 72 05 12 50 00 20 03 02 0A 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ***** onTestManufatureData ***** resut= true, 广播包中 manufacture specific data 字段中MAC地址校验成功. 如果这里显示警告，就是的mac地址不对，这里说一下mac的数据是可以自己写的，但是前提要前后保持一致 ***** onDiscoverService ***** result = true, DiscoverService success Discovered Services ServiceUUID: 00001800-0000-1000-8000-00805f9b34fb ServiceUUID: 00001801-0000-1000-8000-00805f9b34fb ServiceUUID: 0000180a-0000-1000-8000-00805f9b34fb ServiceUUID: 0000fee7-0000-1000-8000-00805f9b34fb ***** onTestHasWeChatService ***** result = true, has WeChatService or standard service ***** onTestHasIndicateCharacteristic ***** result = true, has WeChat Indicate Characteristic ***** onTestHasWriteCharacteristic ***** result = true, has Wechat Write Characteristic ***** onTestHasReadCharacteristic ***** result = true, Has WeChat read characteristic ***** onTestWriteCharacteristicPermisson ***** result = true, has Write permission ***** onTestIndicateCharacteristicPermisson ***** result = true, has Indication permission ***** onTestReadCharacteristicPermisson ***** result = true, Read Characteristic is read able ***** onTestStartIndicating ***** result = true, can Start Indicate ***** onConnected ***** result = true, connected ------onDataReceived------ data length = 20 data dump = FE 01 00 24 27 11 00 01 0A 00 18 84 80 04 20 01 28 02 3A 06 data receive seq = 0 ------onDataReceived------ data length = 16 data dump = 90 59 AF 0E 62 88 (MAC) 62 08 6D 79 64 65 76 69 63 65 data receive seq = 1 ***** onTestRecvAuthReqtWhenStartedIndicating ***** result = true, received auth request pack ***** onTestIsValidAuthReqPack ***** result = true, is a valid auth request pack AuthRequestPack: FE 01 00 24 27 11 00 01 0A 00 18 84 80 04 20 01 28 02 3A 06 90 59 AF 0E 62 88 62 08 6D 79 64 65 76 69 63 65 has BaseRequest no Md5DeviceTypeAndDeviceId field!
