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在以下位置发布的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
但是几秒钟后我的连接超时问题了.我已经执行过一次全新的raspbian构建，并尝试了2种不同的加密狗(AZIO V400和IOGEAR GBU521)，并且我尝试了本教程中的Bluez 5.8和Bluez 5.11，两者均在新的Raspbian负载上进行.
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...

这会使用"Locate iBeacon"应用程序触发iPhone上的"Entered"事件，并以秒为单位显示距离(以米为单位).然后，它将距离:未知"显示为范围，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

看来，iPhone尝试启动与pi的连接，然后未能协商该连接，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撰写信函的步骤，似乎无法确定导致断开连接的原因.我曾尝试更改bluez版本，并尝试了不同的硬件，但无济于事.有什么想法我可能会缺少的步骤吗?我已经搜索了所有我能想到的线索，但是还没有找到答案.预先感谢您的任何建议！
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
尝试将设备设置为广告且不可连接"(3而不是0)，而不是广告且可连接"
Try setting the device to "advertise and not-connectable" (3 instead of 0) instead of "advertise and connectable"
sudo hciconfig $BLUETOOTH_DEVICE leadv 3
几秒钟后，由于笔记本电脑试图连接，我们突然有一个信标掉了下来.将设备设置为不可连接即可解决该问题.
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.
