Android 经典蓝牙(Classic Bluetooth)和低功耗蓝牙(BLE)
跟手机配对会失败,好像是默认的UUID"00001101-0000-1000-8000-00805F9B34FB"不支持,怎么解决?

你好,我在跑该demo时,使用BLE客户端和BLE服务器端对接。在对接成功后,BluetoothGatt的对象调用discoverServices()方法,最后onServicesDiscovered()回调方法一直无法被调用,以至于无法建立可通信的连接,最后BLE客户端点击“写入“消息后闪退。
很感谢您写的这个demo,对我工作中使用蓝牙帮助很大,
我在Ble 开发中有些问题网上很少有答案,比如蓝牙传输速率,
传输速率提高分两个方向:
1 Android 穿到 外围设备的速率,可以通过requestMtu,在
onMtuChanged 回调中获取申请了多少Mtu, 默认23, 减去1个op, 2个句柄,=20个字节(网上都说最多传20个字节...)
2 外为设备传给Android, 如果每次传20个字节,最少间隔7.5ms, 1.25ms一个步距(5个),
每个间隔时间最多传6个包, 120个字节. 因为外围设备(大多是单片机和蓝牙模块透传的) 写数据也有延迟,10字节/1ms, 最后是 没调成120字节/16ms,可以稳定传输20k数据.
为什么连接蓝牙的时候,点击就很快出现断开,基本上没有连接成功过,不像你的截图那样可以连接成功。
dalao你好,感谢你的demo,我想请教下BtReceiver类在经典蓝牙中到底起什么作用呢?可否解释一下,有点看不懂···
你好,我在跑您的demo时,在点击文件传输按钮后就会出现断开连接的情况,这是什么原因呀
跟ESP32的蓝牙连接了一下,一开始有点问题,后来发现是因为每次读取前有个flag,会分为字符串和文件读取。导致ESP32发来的数据无法识别。去掉文件部分或者让ESP32发送前面加上flag就行了。
代码写的很易懂,功能也比较简洁,nb!
小米手机扫描不到指定的蓝牙
请问可以ble中心设备可以同时连接多个外设嘛
支持不支持大数据传输,如果就是要大数据传输,需要怎么封包拆包
