How can we detect ibeacons from a android phone without explicitly switching on the bluetooth or location...?
I want to design an app which detects for the beacon even when the bluetooth is off...please suggest the answer
Sorry, this is not possible. Bluetooth must be turned on to detect t beacons as it requires using the Bluetooth radio to do a scan.
With BLUETOOTH_ADMIN permission (required for scanning anyway), it is possible to detect if bluetooth is off, then turn it on long enough to do a scan, then turn it back off again. The user will see the Bluetooth icon when this happens, and the user will be told at install time that the app requires this permission.

I am using Android management API. I have applied policy to device and turned it to kiosk mode. After a while when I turn on the device, it is not connected to wifi anymore and is still in kiosk mode. Therefore I cannot connect it manually or update its policy. Is there a way to solve it ?
Unfortunately, as you cannot open the wifi dialog and devices cannot update the policy without a connection, the only way to workaround this is to hard reset the device per OEM instruction.
In the future, you can use KioskCustomization to have access to the status bar and navigation buttons so there would be no need to hard reset the device again if there is no connection as you can open the wifi dialog with this.
For people wondering how to escape the kiosk mode. There should be a way for your device to reboot to recovery mode. I my case - samsung tablet - I hold power button and volume down button for a while and when samsung logo appeared a released the power button, but still hold the volume down button. In recovery mode I were able to connect to wifi manually.
Is there a way to make the bluetooth central "forget" a device, so it's not paired anymore?
I know that only some devices Require a Paired Connection to Access Sensitive Data. Let's say I am referring to those. See for example this question
I am looking for something that allows the user to tap on a "forget" button, to later re-pair the device and connect/disconnect to it. (Without having to go to settings app )
This is not possible.
The user has to manually go to the Bluetooth settings and forget the device.
All apps which use BLE and present on the app store ask the user to manually go to Settings and forget the pairing.
Basically, I'm looking for any way to go about this at all, no matter how cumbersome or unintuitive, so long as it can be done on iOS 7 (which the third party SBSettings framework currently cannot), and can be done on a non-jailbroken device.
This is for an app which will be loaded into iPads in a physical enclosure so the power button is inaccessible. The device itself will be in single app mode, which cannot be enabled or disabled except through our network-accessed MDM solution. The issue I'm trying to find a way around is that every now and then, the network connection stops functioning and the only way to re-establish it is to restart the device, which can't be done without an internet connection other than to physically press the inaccessible buttons. The reboot action would be password-locked in a hidden event handler and so inaccessible to normal users. This is not an app that will ever see the app store, so Apple's user interface guidelines don't necessarily apply.
Alternatively, is there any way to enable/disable assistive touch programmatically or any other possible method that will enable rebooting the device while in single app mode without physically touching the power button?
This is not a real answer (just thinking aloud).
Obviously, you can't do this through public API.
I believe, API's like SBReset can't do this either, because they are protected by entitlement.
I believe your simplest option to find some reasonably low level API which crashes and use it to crash a device.
I had exactly the same question some time ago:A way to reboot iOS device or restart Springboard using private API?
P.S. I don't have a way to find these crashes. I would recommnd to talk to jailbreak community (people who come up with jailbreaks for iOS devices). They collect all kinds of crashes. Most of these crashes aren't exploitable. However, you don't need an exploit, you just need a OS crash.
I'm using windows WLAN APIs (Windows Desktop not Metro Apps) to scan WiFi networks.
I'm curious what will be the behavior of the WiFi scan when Airplane mode is enabled before the scan is completed?
I'm trying to create such scenario but it very hard to catch such timing.
Any ideas?
Technically speaking, "Airplane Mode" Takes the Radio Transmitters in your iPhone and changes their frequencies of transmission to frequencies that are sympathetic to Aeronautic Instrumentation, such as Guidance Systems for example.
Due to the frequency change, if you're scanning Networks and then you change the properties of the Network adapter, the adapter has to restart. So, your Scan will be temporarily interrupted.
Test it on your iPhone, download something from App Store and switch modes during the download, see what happens. The Icon will suddenly stop and will display "SEARCHING" and will then re attempt to pick up the connection again.
I have installed the Android SDK and I noticed that the WiFi button is not enabled in the emulator. I want to know, whether this functionality available on Emulator or not, and why. I have been looking for a convincing answer for a long period.
There is no WiFi chip inside emulator, so the button cannot be pressed.
Emulator already has a network connection routed through your host PC, so WiFi is not really needed.
