ibeacon

问题 I have used the raspberry pi to detect the ibeacons and gone through the tutorial provided by Radius Networks here. I made a small script that first turns on lescan and redirects output to /dev/null. Then it turns the hcidump on piping to the output to the script. The output shown by the script is slow. While the advertisement packets are transmitted in magnitude of milliseconds, the result however on the terminal is slow. consequently, the command keeps on showing new output even if you turn

问题 I am running an application with BLE scan. on Samsung S4 after a while or if more tha 10 beacons are around I see this error: 07-18 11:51:57.169: W/bt_userial(7819): userial_read_thread() failed to gain buffers 07-18 11:51:57.169: E/GKI_LINUX(7819): ##### ERROR : GKI_exception: GKI_exception(): Task State Table 07-18 11:51:57.169: E/GKI_LINUX(7819): ##### 07-18 11:51:57.169: E/GKI_LINUX(7819): ##### ERROR : GKI_exception: TASK ID [0] task name [BTU] state [1] 07-18 11:51:57.169: E/GKI_LINUX

问题 Running IOS 9.1 with Xcode 7.1.1 under 10.11.1. Cut'n'pasted this code from this tutorial; and double check it with several other sources/sites. http://hatemfaheem.blogspot.ch/2014/12/how-would-you-scan-for-nearby-ble.html This is the code I have ... import Foundation import CoreBluetooth class BLEManager { var centralManager : CBCentralManager! var bleHandler : BLEHandler // delegate init() { self.bleHandler = BLEHandler() self.centralManager = CBCentralManager(delegate: self.bleHandler,

问题 Having the trouble to connect to IBeacon, I have downloaded the Locate app but it was unable to find my IBeacon. I have also manually configured the ibeacon but without success. Another approach was that I have downloaded the eBeacon app and my IBeacon is visible only in central peripherals, not in the list of Beacons. I think the problem is in the device. Here it is my beacon. Any ideas will be appreciated. Thanks! P.S I have asked the question about the problems for connection to IBeacon

问题 I get the following error when i run a Unit Test in my Android project (I don't get the error while building the app and running it on a device): The BeaconService is not properly declared in AndroidManifest.xml. If using Eclipse, please verify that your project.properties has manifestmerger.enabled=true org.altbeacon.beacon.BeaconManager$ServiceNotDeclaredException: The BeaconService is not properly declared in AndroidManifest.xml. If using Eclipse, please verify that your project.properties

问题 What is the exact difference between didEnterRegion and didRangeBeacons in terms of use case i mean when i should implement didEnterRegion/didExitRegion and when should i implement didRangeBeacons ? What are the each delegate method's exact functionality ? From apple's documentation it's not very clear. - (void)locationManager:(CLLocationManager *)manager didEnterRegion:(CLRegion *)region { } AND - (void)locationManager:(CLLocationManager *)manager didRangeBeacons:(NSArray *)beacons inRegion:

问题 First of all, yes, i have read all other similar questions. Secondly, i am developing app (WP 8.1 WinRT), which must use Beacons. I read a lot about it, and i know, that generally connection with BLE device is not possible without pairing it first. But hope dies last, so i want to ask about any possibilities I have. It is possible to pair devices in code (according to articles I have read - its not, but maybe someone know the way)? Or just obtain nearby Beacons Id or Name, or ANY information

问题 We are discussing a large scale deployment scenario with iBeaons in several locations cross-country. The question was raised as to whether the IDs with which iBeacons advertise their presence is unique? Because our client wants to be really sure that the app only responds to a specific iBeacons and not to something else that's impersonating with the same ID (even if inadvertently). If not unique, does the protocol allow iBecaons to advertise any additional authentication information? 回答1: It

问题 Im building a simple ios app with IBeacon , I'm monitoring a region but I have some issues with enter and exit events. If I go into a region the callback didEnterRegion is fired, but being within the region, turning off bluetooth doesn't fire didExitRegion callback. Is this the expected behavior? This is an issue since I have to be able to detect when the user exits the region. Any idea? Thanks 回答1: For testing purposes you must turn off your beacons or move out of range to get a

问题 I have a project that requires ranging of beacons, I've looked at lots of sample code which all uses CLLocationManager and CLBeaconRegion . My issue with this is that the didRangeBeacons callback only gets called once per second. Although I've not found any code examples specifically for beacons, am I correct in thinking that CoreBluetooth would give me more control over how often my app scans for beacons? My thinking is that if I can scan for beacons at a higher rate (say ever 200ms) I will
