I'm working on a project using Ubertooth. We will use Ubertooth to label using the visualized wave forms of the RSSIs received and determine what the signal is (WIFI, BLUETOOTH, ZIGBEE, ETC) using deep learning.
Currently I've been experimenting with a Linux Ubuntu environment using Ubertooth and some simple examples.
My question is whether Ubertooth can be implemented on an Android smartphone (comparably of the latest models).
Ubertooth knows it's a kind of dongle that scans the 2.4 GHz frequency band and gets the signal's value. But Android smartphones also scan and connect to wifi and Bluetooth signals.
So I thought that it would be possible to implement the function of Ubertooth using only Android smartphone. I want to know if it's possible to think and why. If there is anything I misunderstand, it would be appreciated.

Ok, I am starting to develop a new app but I do need to know if it is possible before I begin. I have no experience with iBeacons, beacons or anything BLE related so please forgive my ignorance here.
Problem: I want to use my Mac Bluetooth and send a BLE notification to my iPhone and my Android phones (think of the Starbucks app and how it sends you a Beacon). Question is: Is it possible for my iOS SDK / Android SDK (is there any kind of delegate or API) that will receive my BLE notification and open a specific app based on that? In other words, my Mac would send a simple Beacon UDID and my phone should launch my app based on that. And what libraries (I use ruby, but could do PHP, Python, anything on the Mac side) that would allow me to do that on both ends?
Yes, this is possible to do, but there are some challenges:
OSX Yosemite cannot transmit as a beacon, at least not with its built-in bluetooth interface. At a minimum you need to add an external bluetooth dongle. You could then use an off the shelf-program like MacBeacon to transmit.
While there are beacon detection tools for both iOS (CoreLocation, which is built-in) and Android (Android Beacon Library, which is an open source add-on), both require a custom App to be installed on the phone to detect beacons.
You would need to make a custom app as described in (2) that would launch yet another app depending on the beacon identifier detected. This would require Objective C skills for iOS and Java skills for Android.
I want to know how iBeacon works actually. I found the sample code of AirLocate, but couldn't figure out how it works. iBeacon is works on BLE, so it may be possible for do data communication with other BLE supported devices via bluetooth?
As it possible to make data transfer between iOS - android device via bluetooth using BLE or beacon?
iOS had already announced iBeacon technology, but didn't find out any technical specification document regarding this. I also want to know how it works on android?
Can some one please describe about this technology and is it possible to make data-communication via bluetooth between iOS-iOS device, and iOS-Android Device?
No, you cannot communicate between devices using iBeacons because an iBeacons are transmit only. Mobile devices, both iOS and Android can both hear iBeacons, but they cannot talk back.
iBeacons work by transmitting a 3-part identifier and a transmitter power reference value every second (or more often.) That's it. They do nothing more. SDKs in iOS and Android listen for these signals and report them to your app, but the rest is up to the app developer.
What you suggest may be possible with a custom Bluetooth LE beacon, but it would need to be significantly more complex than an iBeacon, and you would have to build your own.
Here are a couple of links to give you more info:
How iBeacons work on Android from Radius Networks
iBeacon overview by Dave Addey
Full disclosure: I work for Radius Networks.
I'm working on a BLE proximity sensing feature based on Android and need some information.
Currently I see there are no BLE beacons manufacturers for android. I found 2 so far for iPhone.
1) http://www.estimote.com
2) http://www.gimbal.com
Estimote claims that their devices are generic but mainly they are publicized for iBeacons. So I'm not sure whether I should order them for a feature on Android.
Secondly gimbal explicitly mentions that their devices won't be enabled for android for proximity sensing.
So if any of you know where can I order BLE beacons compatible with Android please let me know.
Another thing, for prototype testing I was wondering whether I could use a Android BLE capable tablet or smartphone as a beacon to emit BLE signals?
Till now the documentation for android only suggests how to detect a beacon, But I'm not sure whether an Android device can be used as a beacon.
Any insights?
There is a BLE Beacon manufacturer for Android: Radius Networks
You can detect any standard iBeacon on Android using our Android iBeacon Library.
You can try it out yourself with our free iBeacon Locate app, which is based on this library. My company also sells both software and hardware iBeacons that I guarantee work with Android. But again, any standard iBeacon will work, too. Don't take my word for it -- just download our free app and use it to see one of our iBeacons. (We even have a free virtual machine you can use!)
It is currently not possible to make an iBeacon out of a stock Android device because the Bluetooth LE APIs, introduced in Android 4.3, do not support the peripheral mode needed to transmit advertisements like an iBeacon.
EDIT: It is now possible to make rooted Android 4.4.3 devices transmit as an iBeacon. See here.
I tried simple BLE scan app on Android, but the callback for LeDevices always returned null for UUID[]. Also, finding based on know UUID didnot work.
To add to David's reply. I have tried Radius Networks SDK, pretty clean. I like it.
Also, Estimotes has released their Android SDK today(1/7), which is good. The sample App shows notification, Distance, Major-Minor. I tested with 3 Estimotes & also with iPhone's app (making the iPhone as iBeacon). It works well, give it a try.
Note that you have to modify the code
change the ESTIMOTE_PROXIMITY_UUID value to the UUID that you are watching for.
Hope it helps.
I have been searching for a while now and decided to post a question here to see if someone had already traveled down this specific road.
I am developing a bluetooth enabled device, using the Bluegiga BLE112 chip. They announce this chip to be easily used with iOS devices (and this was our main reason for choosing it)
The device will need to communicate with an App, that we need to be developed for iOS, Android, Windows Phone, and Blackberry. Due to this need, I've decided to use Rhomobile, as it seems to be the only one that supports developing BT apps for iOS without having to develop further plugins.
I only need to send small messages (like commands, small strings) and sometimes a bigger file to the device's internal memory.
On Rhomobile's BT documentation, they state that for iOS it is only possible to comunicate between iOS devices ( i'm thinking that they say this because of the MiFi limitations imposed by Apple, but that using Bluegigas chip are not a problem...)
My question is:
Since Bluegiga's documentation has examples of devices communicating with iOS using their chip, i should be able to develop using Rhomobile and not suffer from the limitation stated above. I wanted to be as sure as possible before making my company spend money ordering the chips and development board and what not..
Has anyone tried this, is my thinking missing something?
Thank you all for your time.
Daniel
Good Question, I think I can understand the reason for your confusion.
The main reason is many people/products/frameworks does not clearly mention if they are talking about Bluetooth Classic or Bluetooth Low Energy (BLE).
These are both 2 different things and even thougfh they are called "Bluetooth" one cannot talk to the other.
(Some devices can be both Classic and Bluetooth Low Energy, which allows it to connect to either types)
Ok now comming to your Question :
THE bluegiga dongle is BLE
The Rhomobile is refering to the Bluetooth Classic version of the API.
On iOS the BLE APIs are open to applications, but Classic is limited on iOS , one way for Apps to use Classic Bluetooth on iOS is via the Gamekit APIs but that is possible only when talking with iOS devices, so it wont connect to another Android or Win device that is also Classic.
Needless to say with BLE APIs you cannot connect to calssic anyways.
The bluegiga examples are BLE examples, and apple also has good documentation and examples / samples on how to use BLE so yes it is easy to build a device and app using BLE on iOS.
There is nothing special abut any particular chip yo ucan use any BLE chip - there are many vendors today.
BUT Android (and I guess Windows as well) does not yet have BLE APIs for applications to use :( (Bit I think is is comming soon :))
So I hope this clears things up a bit.
So I'm trying to hook up a Kinect to an Android tablet using any means necessary. I would preferably like to avoid a windows machine or arduino board in the middle.
The method I've already tried is to have a C# program (the kinect sdk uses C#) communicate with the android device. I tried to figure out how to send a message through usb, and decided to do port forwarding. This worked, but was slower than I would like it to be.
I guess the question is can I connect it to Android as a usb device or accessory and communicate via JNI?
In theory you should be able to use the OpenNI for ARM. I've seen Hirotaka's demo of OpenNI running on Linaro Android but using an Asus Xtion Pro sensor and a Panda board.
Hirotaka also posted notes on his setup.
Doing a quick youtube search reveals examples with Kinect and Android tablets.
Side note: I don't I understand why you're trying to use C#: you'll be writing Android applications in Java and OpenNI has a Java wrapper.
