ibeacon precision

The ibeacon module used in this article is April Beacon, as to what is ibeacon. This article does not explain, the specific please self-examination.The information that a April beacon carries is as follows0201061AFF4C0002159069BDB88C11416BAC3F33468C2788A3044B0378C60C09417072696C426561636F6E051250002003020A0000000000000000000000What do you mean, exactly?

It only has 30 bytes of broadcast data, so it is adapted to the 31-byte limit.What makes Bluetooth broadcast an ibeacon?

Recently the company is engaged in Ibeacon, because the company another learning Android, and the rest of the people, only I touch Java, Android, so I only to do this.Statement, I am a C # programmer, Java, Android are weak, just slightly involved, do not understand, the error, a lot of advice.At first, I search the Internet ibeacon information (using Baidu, alas, it seems I am 2B programmer AH), the most d

First of all, tell me what ibeacon is:IBeacons is the function of the IOS7 system. Use Bluetooth 4.0 (Low power Bluetooth) for data transfer (iphone 4s + devices). Handheld devices can receive signals from Ibecons base stations within a certain range (up to 50m). Any Bluetooth device that implements the Ibeacon protocol can act as a ibeacon base station. Differen

IBeacon is a new function of iOS7. It uses BLE to implement indoor positioning and is accurate to the centimeter level. The test uses two iPhones (BLE supported), one as the iBeacon base station broadcast signal, the Code uses the official source code AirLocate, and the other as the receiving end, directly using the AirLocate downloaded by the App Store ). 1. Main broadcast code NSDictionary * peripheral

of the benefits of using a real number as an evaluation measure is that it can help us quickly decide if we need to make some improvements to the algorithm. Increase the accuracy from 99.2% to 99.5%, but does our improvement really work, or do we just replace the code with something like always predicting y=0, so if you have a skew class, using categorical accuracy is not a good way to measure an algorithm, Because you may get a high accuracy, or very low error rate, but we do not know whether

Due to improper use of float or double, there may be an issue of loss of precision. The problem probably can be understood by the following code : [Java]View Plaincopyprint? Public class Floatdoubletest { Public static void Main (string[] args) { float f = 20014999; Double d = f; Double d2 = 20014999; System.out.println ("f=" + f); System.out.println ("d=" + D); System.out.println ("d2=" + D2); } } public class Floatdouble
