您好！

感谢您联系我们！在低功耗蓝牙应用中、在 F2 SDK 上、只要未超过 SysConfig 中的最大连接数、单个外设就能够连接到多个中心设备。在这种情况下、如果将最大连接数设置为2个或更多、则可以同时连接到2个不同的电话。两个器件都可以在单个外设中读取和写入相同的 UUID。但是、请确保手机应用程序注意写入和读取的最新数据是什么。

是否会存在如下现象：

数据冲突：如果两个手机同时向同一个UUID写数据，可能会导致数据冲突。因为蓝牙连接是基于点对点的通信方式，同一个UUID在同一时间内通常只能被一个设备占用进行数据传输。

您好，

你是绝对正确的! 虽然时间间隔很短，但可能会发生数据冲突，导致丢弃尝试发送的数据包。因此，请确保移动电话应用程序牢记写入和读取的最新数据是什么。
