HC-05 蓝牙模块开发 - 创客硬件开发 - 清泛IT社区,为创新赋能!
...
通过厂商App连接串口测试,发现HC-05模块是经典蓝牙2.0,并不支持蓝牙5.0(低功耗BLE),它需要配对码进行配对,App Inventor 2 中使用“蓝牙客户端”组件,而非BLE拓展,必须在手机设置中配对成功才能出现在蓝牙列表中。

为啥“蓝牙客户端”组件在连接设备时就没反应了? - 创客硬件开发 - 清泛IT...
...可以考虑是否时硬件没有开机,或者硬件蓝牙版本是否是2.0经典蓝牙。最终用户使用ble拓展,成功连接及测试成功。
也就是硬件支持的是ble低功耗蓝牙,这里也为我们提供了一个新的排错思路,蓝牙协议版本不一样,是无法...
