BLE<Bluetooth>：如何解释 BLE 的 nRF 日志
BLE<Bluetooth> : How to interpret nRF logs for BLE
我们的 BLE（蓝牙）设备运行良好。大多数时候它都有效，但有时我们会收到错误的响应并收集其日志。这些日志是从 nRF android 应用程序收集的。
这里有一些问题：
- 你能解释这种记录行为吗？
- 错误响应命令中的“AT”“%S”“&W”有什么意义？
- 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、发现服务和订阅特征BLE的所有概念。
作为Central的设备在完成与外围设备的连接后，发现外围设备提供的服务并随后订阅发现的特性。

我们的 BLE（蓝牙）设备运行良好。大多数时候它都有效，但有时我们会收到错误的响应并收集其日志。这些日志是从 nRF android 应用程序收集的。
这里有一些问题：
- 你能解释这种记录行为吗？
- 错误响应命令中的“AT”“%S”“&W”有什么意义？
- 如果你知道一些好的参考资料；如何解释这些日志？请分享。

谢谢。
日志是关于连接、发现服务和订阅特征BLE的所有概念。
作为Central的设备在完成与外围设备的连接后，发现外围设备提供的服务并随后订阅发现的特性。
这里是guide
知道这一点，解释日志就很容易了。
