linux - 使用hcidump获得RSSI

3年前。

This question was migrated from Raspberry Pi Stack Exchange because it can be answered on Stack Overflow. Migrated。
为了读取原始rssi值，我们使用一个名为hcidump的实用程序来监视蓝牙hci数据。使用hcidump命令，我们可以在收到查询响应消息时读取原始rssi值。为了获得每个响应包的rssi值，我们首先将查询模式设置为使用rssi进行查询。
HCI功能启动定期查询。
我不知道如何使用hcidump只获取rssi原始数据，或者如何开始定期查询。我看到了所有的手术，但我不能。
我让hcidump--raw来获取原始数据，并尝试解析这些数据来获取rssi，但是我不知道hex是rssi信息。
这就是我得到的

现在我需要知道哪个是rssi值。

最佳答案

您可以尝试使用sudo hcidump [-a]这将获得附近所有蓝牙设备的名称和rssi值。您可以查看使用hcidumphere可以做什么。
