Raspberry Pi iBeacon 连接超时 [英] Raspberry Pi iBeacon connection timing out

问题描述

我目前正在尝试 RadiusNetworks 发布的 Raspberry Pi iBeacon 教程

I am currently attempting the Raspberry Pi iBeacon tutorial posted by RadiusNetworks at

http:///developer.radiusnetworks.com/2013/10/09/how-to-make-an-ibeacon-out-of-a-raspberry-pi.html

但我在几秒钟后遇到连接超时问题.我执行了一个全新的 raspbian 构建，并尝试了 2 个不同的加密狗(AZIO V400 和 IOGEAR GBU521)，我已经尝试过根据教程使用 Bluez 5.8 以及 Bluez 5.11，两者都在新的 Raspbian 负载上.

but I am having issues with the connection timing out after a few seconds. I have performed a fresh build of raspbian, and have tried with 2 different dongles (AZIO V400 and IOGEAR GBU521), and I have tried with Bluez 5.8 per the tutorial as well as Bluez 5.11, both on fresh Raspbian loads.

当我调用启动脚本时，我看到:

When I call the start script I see:

pi@piBlueTest ~ $ ./start
Launching virtual iBeacon...
LE set advertise enable on hci0 returned status 12
< HCI Command: ogf 0x08, ocf 0x0008, plen 44

这会使用定位 iBeacon"应用在 iPhone 上触发进入"事件，并在几秒钟内以米为单位显示距离.然后它会显示距离:未知"作为范围，持续几秒钟，然后发生退出"事件.当我在运行hcidump"的情况下运行序列时，我得到

This triggers an "Entered" event on the iPhone using the "Locate iBeacon" app, and shows a distance in meters for a few seconds. It then shows "Distance: unknown" as the range for several more seconds, followed by an "exit" event occurring. When I run the sequence with "hcidump" running, I get

似乎 iPhone 正在尝试启动与 pi 的连接，然后在协商该连接时失败，从而终止了广告.

It appears that the iPhone is trying to initiate a connection to the pi, and then fails at negotiating that connection which then ends the advertisement.

我已经完成了从教程到信件的步骤，似乎无法确定是什么导致了断开连接.我尝试更改 bluez 版本，并尝试不同的硬件，但无济于事.任何想法我可能会遗漏哪一步?我已经搜索了所有我能想到的线索，但还没有找到答案.提前感谢您的任何建议！

I have completed the steps from the tutorial to the letter, and cannot seem to determine what is causing the disconnect. I have tried changing bluez versions, and tried different hardware, but to no avail. Any ideas what step I may be missing? I have searched everything I can think of for clues, but have not found the answer yet. Thanks in advance for any advice!

推荐答案

尝试将设备设置为advertise and not-connectable"(3 而不是 0)而不是advertise and connectable"

Try setting the device to "advertise and not-connectable" (3 instead of 0) instead of "advertise and connectable"

sudo hciconfig $BLUETOOTH_DEVICE leadv 3

由于笔记本电脑尝试连接，我们突然发现一个信标在几秒钟后关闭.将设备设置为不可连接解决了问题.

We suddenly had a beacon going down after a few seconds due to a laptop trying to connect. Setting the device to not-connectable solved the problem.
