在 iOS 6 上，BLE 允许您发送大约 20 字节的数据块.有关如何分割要发送的数据以及如何使用基于通知的传输的示例，请下载 BTLE Transfer Apple 示例应用程序.

On iOS 6, BLE allows you to send around 20 byte chunks of data. For an example of how you can slice up the data to be sent and how to use notifications based transmission, download the BTLE Transfer Apple Example application.

为了更好地了解您可以达到的速度，我建议您分析此图表 http://www.scriptreactor.com/conn_interval-throughput.pdf 它显示了作为连接间隔函数的可实现速度.iOS 没有为您提供如此细粒度的控制，但此信息对您计算仍然很有价值.

To get a better understanding of what speeds you can achieve, I suggest you analyze this diagram http://www.scriptreactor.com/conn_interval-throughput.pdf It shows the achievable speeds as a function of connection interval. iOS does not give you such a fine grained control but this info is still valuable for you to calculate with.
