我们的 BLE(蓝牙)设备运行良好。大多数时候它可以工作,但有时我们会收到错误的响应并收集它的日志。这些日志是从 nRF android 应用程序收集的。

这里有一些问题:

  1. 你能解释这种日志记录行为吗?
  2. 错误响应命令中的“AT”“%S”“&W”是什么意思?
  3. 如果你知道一些好的参考资料;如何解释这些日志?请分享。

日志是关于连接、服务发现订阅BLE 的所有概念的特征。

在完成与外围设备的连接后充当中心的设备发现外围设备提供的服务并随后订阅发现的特征。

这里有一个指南

知道这一点,很容易解释日志。

12:58:13.986 "(0x) 07-23" 收到

您在错误响应中看到的奇怪值(“AT”、“%S”、“&W”)是接收到的数据的十六进制到 ASCII 转换。该应用程序尝试将从特征接收到的字节转换为 ASCII 字符。例子

I 14:50:20.914 从 569a2000-b87f-490c92cb-11ba5ea5167c 收到通知,值:(0x) 41-54, "AT" A
14:50:20.914 "(0x) 41-54, "AT"" 收到

十六进制值 ASCII
0x41 一个
0x54

所以 0x 41 54 --> AT
