测量接近与树莓丕蓝牙 [英] Measuring proximity with bluetooth on raspberry Pi

问题描述

我一直在尝试使用这个脚本<一个href=\"https://$c$c.google.com/p/pybluez/source/browse/trunk/examples/advanced/inquiry-with-rssi.py?r=1\" rel=\"nofollow\">https://$c$c.google.com/p/pybluez/source/browse/trunk/examples/advanced/inquiry-with-rssi.py?r=1但似乎袜子= bluez.hci_open_dev（的dev_id）返回一个非工作插座。每次袜子被传递给函数错误（9，坏文件描述符'）被抛出。

I've been trying to use this script https://code.google.com/p/pybluez/source/browse/trunk/examples/advanced/inquiry-with-rssi.py?r=1 but it seems that sock = bluez.hci_open_dev(dev_id) returns a non-working socket. Every time sock is passed into a function error(9, 'Bad file descriptor') is thrown.

本脚本是pretty老所以有一个像样的机会它不工作了。所以，我有两个问题。有谁知道如何使用pybluez库（或一个更现代的等价物）来衡量一个蓝牙设备的接近与树莓派？

This script is pretty old so there is a decent chance it doesn't work any more. So I have two questions. Does anyone know how to use the pybluez library (or a more modern equivalent) to measure proximity of a bluetooth device with a raspberry pi?

和我在做什么错这个脚本是导致我建立一个破碎的插座？

And what am I doing wrong with this script that is causing me to build a broken socket?

感谢。

推荐答案

试试这个：

运行 hcitool dev的，让您的蓝牙设备的地址。

Run hcitool dev to get the address of your bluetooth device.

在你的联系，变线120脚本：

In the script you linked to, change line 120 from:

dev_id = 0

到

dev_id = bluez.hci_get_route(ADDRESS_FOR_YOUR_BLUETOOTH_DEVICE)

要衡量接近，该脚本调用函数

To measure proximity, the script calls the function

device_inquiry_with_with_rssi(sock)

应打印的蓝牙装置的ID及其相应的RSSI值（见行95-102）的列表。通常情况下，设备必须在配对模式的调查结果中显示。该函数也返回的ID / RSSI来的名单为一个数组，这样你就可以从自己的code称它为和处理返回的结果。 RSSI值表示一个设备的信号强度，所以是接近的间接测量（参见<一href=\"http://stackoverflow.com/questions/13705647/finding-distance-from-rssi-value-of-bluetooth-low-energy-enable-device\">Finding从蓝牙低功耗的RSSI值距离使设备）。
