这是一个很奇怪的问题, 但我知道这是可能的。
我试图用特定频率广播信息包,我想用一个运行应用程序的电话来接收这些信息包。 电话不需要连接任何网络就可以这样做,而只需打开wifi即可。 广播设备不需要从电话中获取任何信息,把每个信息包发送到电话也不必得到保证,这跟UDP一样。
我从哪开始呢?对于手机来说,这有可能不扎根吗?是否有某种FCC条例禁止这样做(针对标准的wifi频谱 )?
我知道这是可能的, 因为它正是路由者如何告诉一个可以连接的电话。 提前感谢任何输入 。

虽然可能存在类似技术,但我对iOS的开发并不熟悉。

网络“名称”和路由器MAC地址(BSSID)包含在结果中。您可以将这些包和编码数据广播到这些字段中。
因此,我希望您的留言简短,因为您每包会收到38字节(Google搜索,但无法找到所有(甚至大多数)装置通用的解决办法。
