如何获取Kontakt ibeacons的电池电量 [英] How to get battery level of Kontakt ibeacons

问题描述

kontakt的ibeacon信标布局为
m:2-3 = 0215，i:4-19，i:20-21，i:22-23，p:24-24，d:25-25

The ibeacon beaconlayout for kontakt is
m:2-3=0215,i:4-19,i:20-21,i:22-23,p:24-24,d:25-25

我正在使用altbeacon 图书馆用于android进行检测，但无法获取信标的电池电量答案这里表示他们正在传输功率电平，但我无法获取.进一步评论

I am using altbeacon library for android for detecting it but i am unable get the battery level of the beacon an answer here says that they are transmitting the power level but i am unable to fetch it. Further the comment on this page (from line no 100 to 103) describes the byte structure hope this helps.

我如何从信标获取电池​​电量.

How can i get the battery level from the beacon.

推荐答案

如果您的信标布局表达式对该信标是正确的，则可以使用以下命令读取d25-25数据字段的电池值:

If your beaconlayout expression is correct for that beacon, then you can read the battery value for the d25-25 data field with:

long batteryLevel=beacon.getDataFields().get(0);

在此处查看有关读取数据字段的文档:

See documentation for reading data fields here:

http://altbeacon.github.io/android-beacon-library/javadoc/org/altbeacon/beacon/Beacon.html#getDataFields()

但是，问题中的第一个链接提到该字段位于信标的扫描响应"中.如果该说法正确无误，则意味着电池电量根本不在广告中，因此，如果不单独轮询此信息，您将无法获得该电量.

However, the first link in your question mentions the field is in the "scan response" of the beacon. If that statement is true and not a misstatement, that means the battery level is not in the advertisement at all, so you will not be able to get it without separately polling for this info.
