I would like to get my hands on Spyder Bluetooth wearable wireless ECG device and transmit the data to an app.
Now I'm fairly new to Bluetooth communication, so can someone please direct me to reliable source that can help me distinguish data-transmission via Bluetooth.
Thanks in advance!
Your best resource would be from Apple's Developer site. They have a few sample projects that do exactly what you are after as well as heaps of documentation.
You can find the documentation here:
https://developer.apple.com/bluetooth/
Edit: The above is for IOS, just noticed you are after an android solution as well. Someone else will need to point you in the right direction for that.

Checked so far : this stack post, this one and official docs
I am not really familiarised with the Bluetooth api, yet I couldn't find something to clarify based on my need.
What I am trying to achieve is: Using my android device (as server in this bluetooth connection) to push data to the other device (which can be on any platform)
Seems simple, and I might think about it in a complicate way (was thinking I might provide some interfaces / callbacks to the client part)
Also, my implementation should not affect the client side.. I am a bit stuck into this, if anyone could clarify it a bit, or come up with a decent sample where the code is described a bit,
Thanks in advance, and Happy Coding !
your phone can act as a master(host) device Here is a example you can implement
https://github.com/bauerjj/Android-Simple-Bluetooth-Example
this example uses Bluetooth to connect with HC-06 module but you can use it with other devices
I am trying to add support for bluetooth devices like headsets/headphones/car stereo to my android app which allows user to make SIP/VoIP calls. I am trying to mostly address the requirements of Answering and Ending of calls using button on bluetooth headsets, other buttons/features handling is good to have.
With the search I have done and all the text I have read so far, I have come across the following-
One common way suggested everywhere is registering to ACTION_AUDIO_STATE_CHANGED. But this doesn't really helps me. Intents for it are sent every time the button on Bluetooth headset is pressed And also when we start the ring tone on bluetooth headset.
A very common solution I found was use of Bluetooth Adapter class. There isn't much you could do with it. So again not helpful.
Another approach I came across is the use of Vendor specific headset events. After some efforts I was able to get this working for specific Plantronics Bluetooth headsets. Supporting Jabra is important.
One more approach I came across is binding with IBluetoothHeadsetPhone.aidl, the way the phone app does it. I could find very little information on it, not enough to go ahead and implement any thing.
If anyone has done such things, I think the problem I am facing is not an uncommon one, I just believe it is not documented well.
Any pointer, approach, link would be appreciated.
I will try to add more info as I find any or any other approaches I try. Please ask for details if you need any more on the solutions I have tried. And please suggest changes instead of just flagging the question.
Thanks in adv.
Sorry about the late post. I was able to find a solution for this issue. It is not simple fix.
You need to use ConnectionService from Android telecom framework. Check out this link here & here. After this your VoIP calls will have cellular call like treatment.
I realize that this is the kind of question that frequently gets a lot of (well deserved) "what have you tried" comments and down-votes, but I'm hoping that by the time I'm done asking I can avoid that.
I've been looking around but unable to find the answer to how one goes about writing an application that consists of the following three things:
An Android app that connects to a host device via bluetooth
Communication io layer that sends signals back and forth on
that bluetooth connection
A host resident native app (preferably Unity3D, or AIR) that can receive/send messages back and forth to the connected app.
I have written many Android applications so I am not in need of any kind of "getting started" hand-holding, rather I just need some guidance (preferably in the way of a web link or book tutorial) on what it takes to utilize bluetooth and how one actually communicates via it.
Thanks in advance for all useful tips.
Here are a few links that I found in terms of Bluetooth connections
First of all the dev guide(I assume you have already looked here, but if not this is a good place to start)
http://developer.android.com/guide/topics/connectivity/bluetooth.html
http://developer.android.com/reference/android/bluetooth/BluetoothDevice.html
This one is a basic tutorial on how to Bluetooth on android
http://luugiathuy.com/2011/02/android-java-bluetooth/
This is a long PDF on Bluetooth programming in general (I haven't read it, but from what I have seen it looks over in depth) it covers java and OSX, but not android
people.csail.mit.edu/rudolph/Teaching/Articles/BTBook.pdf
Here is a similar SO question which might contain helpful links
Code samples for Android Bluetooth programming
This is the best Bluetooth open source project that I could find for android, it doesn't fit your description over well, but here it is anyways
http://code.google.com/p/bluetooth-remote-control/source/browse/#svn%2Ftrunk%2Fsrc%2Fpro%2Fapus%2Fblueremote
I realise that a lot of these links are simpler than what you really want, if I find anything more complicate I will add that.
I would like to develop a Remote application for Peer-to-peer Android Device using TCP/IP connection. once one of the device successfully remote to the other, he/she will be able to see what the other device is doing (example : doing drawing with an application, etc).
Is this possible to do or there is other way that is more efficient to do ? Any reference/road map is appreciated. code samples are greatly appreciated.
Here have pair of projects implementing a remote service and a client for it:
https://github.com/commonsguy/cw-advandroid/tree/master/AdvServices/RemoteService/
https://github.com/commonsguy/cw-advandroid/tree/master/AdvServices/RemoteClient/
I think this can help you..
Thanks...
If remote means on the LAN, you can use IP multicasting. If remote means the WAN, then you'll need a fully fledge P2P framework, with NAT traversal solutions, such as JXTA for example. Google JXTA and you will find info, including code samples. It is not the only solution, you could explore JGroups too.
There are UDP based P2P frameworks too. These are a bit better at NAT traversal, but you're left with the duty of putting the pieces of the puzzle (i.e., data slicing) back together.
I'm trying to create an Android app which provides a user with feedback such as haptic/textual based on a bluetooth signal it receives from a transmitter.
Could anyone recommend any article/book where I could get some good information? Can't seem to find anything useful myself.
Much thanks.
