Android :: Adapting Bluetooth Chat For Multiple Devices

Jun 1, 2010

I'm doing a college project on Bluetooth for Android, and I'm trying to understand how to manage communication between multiple connected devices. Eventually I'm going to develop a multiplayer Bluetooth Game.Currently I've adapted Android's sample app BluetoothChat to connect my three Nexxus One phones.1 connects to 2 who connects to 3.1 sends its messages successfully to 2. 3 sends its messages successfully to 2 as well. 2 can send its messages successfully to 1 and 3, as it shares a ConnectedThread with both. But I can't figure out.how to handle getting communication from 1 to 3. Does anyone have any examples of communication between multiple devices or has done this themselves?

General :: Find Bluetooth Speaker That Can Retain In Its Memory Multiple Devices

Feb 22, 2012

I am trying to find a Bluetooth speaker that can retain in its memory multiple devices (5 preferred but 3-5 is okay too). I know the Bose Soundlink does this, but it is more money than I want to spend right now. I have an imonster, but it only remembers one device at a time.

Android : Multiple Person Chat App

May 14, 2010

Every morning at 7:45 my friends and I "have coffee" together on line. We use MSN live. I have yet to find a chat app that will allow me to have ALL of my friends in the same window. Everything I have found only allows one person per window . . .any ideas?

If I was organized I would tell you which ones I have tried but haven't kept track . . .because I gave up - now am back at it again!

Just dawned on me - if my friends are already in msn chat- I need an app that they can invite me into that conversation - have to have msn chat? Because that will only let me have one person at a time.

Android :: Multiple Exchange Accounts / Different Chat Clients

Dec 11, 2009

With Google Talk I'm automatically logged in with my main gmail account. Is there a way to add other gmail accounts to this? Or swap to a different account when I need to? How about non-gmail accounts? Can I add an AIM account, for example? Is there an app that can manage multiple chat accounts? I use Adium on my Mac to have 3 or 4 different chat accounts open (useful for work, people who don't have gmail etc.) and I'd love to do the same thing with my Droid.

Android :: Point Of Synchronization - Bluetooth Chat Sample?

Dec 30, 2009

What is the point of the synchronization here? Why not just use: mConnectedThread.write(out); ?
The code snippet is from the BluetoothChat sample for Android (found here)
http://developer.android.com/resources/samples/BluetoothChat/index.html

/**
* Write to the ConnectedThread in an unsynchronized manner
* @param out The bytes to write
* @see ConnectedThread#write(byte[])
*/ public void write(byte[] out) {
// Create temporary object ConnectedThread r;
// Synchronize a copy of the ConnectedThread synchronized (this) {
if (mState != STATE_CONNECTED) return; r = mConnectedThread;
} // Perform the write unsynchronized r.write(out);
}

Android :: Bluetooth Chat - Pass Complete Incoming Message

Nov 12, 2010

I am using Bluetooth Chat sample app from Android website. I want to pass the complete incoming message, (message format included in the code below as this website is parsing the message for me which is my job in the code as well to a function which removes the tags and extracts message name and value and uses it for further action. The readMessage string (in the switch case Message_Read) sends selected characters and omits few special characters. Following is the code from Bluetooth Chat app (from Android website).I am not able to receive the complete message in the format which I have mentioned in the code. It gets displayed in multiple lines and many characters get deleted. Any suggestion why this is happening?

Android :: Purchased Apps On Multiple Devices?

Mar 20, 2010

I have a question about the way the Android market handles purchased apps.I've seen in other posts where if you upgrade to a new phone, your purchased apps will follow you.But how about if you use more than one Android device? For instance, later this year I may get an Android tablet. Presumably the apps I purchased on my Droid will downloadable on the tablet. But will they remain downloadable on my Droid? And if I purchase an app on the tablet, will it also be downloadable on my Droid?It seems to me that if the apps are associated with your account, then you should be able to download them on multiple devices.I was just wondering if anyone has actually tried and confirmed this.

Android :: Use 2 Bluetooth Devices At Same Time

Jun 15, 2009

I bought a stereo bluetooth receiver from DealExtreme for $13 so I could use it in my car. It has a built in mic, so if calls come in, I can pick them up, but I drive a convertible, so it's too noisy in the car to use that.

I also have a jawbone bluetooth headset that I use in the car...it works great for phone calls in a noisy enviroment.

I just discovered that if I go to Settings:Wireless Controls:Bluetooth Settings and long press on the BCK-08 (the stereo bluetooth module), I can select options, and uncheck the 'phone audio'.

Now, I can use both at the same time...and the cool thing is that if a call comes in while listening to music, it mutes the music till I hang up, then starts it back up where it left off!

Android :: Query Bluetooth Devices. It Is Possible?

Jan 27, 2009

I know there isn't bluetooth API in 1.0 SDK, but I have a doubt. I need to know the visible bluetooth devices. That is, I only need do a scan of the bluetooth devices and save the diferent addresses. I don't need connect to them.

I have read here

http://groups.google.com/group/android-beginners/browse_thread/thread...

that API "only expose functionality to use/control headsets (audio profile)."

And now my question: It is possible do this functionality? Can I find which bluetooth devices are visible?

HTC Desire :: Increasing Number Of Multiple Exchange Accounts In Android Devices?

Sep 19, 2010

Is there any plan to increase the number of Exchange type accounts on HTC Android devices. Maybe in the new Sense Updates? Why did HTC not implement the code included in the stock Androind mail app (since at least 2.1), or at lease leave it alone! Since Hotmail has improved it's service to offer an Exchange style connection option there is a real day to day need to have at least two Exchange accounts on one device. I have been using the stock 2.2 android email client for some time and although it feeds into the unified calender app it does not feed into the Sense contacts ribon etc., I also goes high CPU at times (file conflict?) so is not a suitable workaround. And no I do not wish to use a third party app such as countdown, I like that with HTC's Sense system all things feed into a common thread - third party apps I have found have their own databases for email & calender etc. which I do not want.

Android :: How Does A Solo / Small Group Of Developers Test On Multiple Devices?

Nov 10, 2010

First off, sorry if this is too subjective, I just didnt know how else/where to ask.Anyway, in the light of all my recent questions, I'm getting ready to release an Android app soon, and most of the testing has been done on my phone, the Droid. I really dont have the money to test on "multiple" devices, nor do I know anyone with an older phone that I could ask for help that would possibly get any kind of bug. Not to mention, when I do get a bug report, how would I go about fixing it for that particular phone without having to buy it to make sure it actually gets fixed, or that the person didnt just came across a one-time freakish accident of a glitch?

Android :: Activate SPP Profile Of Bluetooth In Devices

Oct 27, 2010

I am trying to use Bluetooth SPP to communicate over it. In some Android phones, SPP profile is not activated. I faced the problem in the application that SPP was not activated and so the connection could not be established over bluetooth and when I started another app that is 3g hotspot which I think activates SPP and I was able to connect over bluetooth in my app.

So, how can we actually activate SPP profile of bluetooth in Android devices? And does all the android devices has SPP profile?

General :: Multiple Devices Not Downloading While Using WiFi?

Jan 17, 2013

We have multiple Android devices in our home my Motorola Photon Q and my fiance's Samsung Galaxy S2. In addition to our Motorola Xoom. Recently my finace and I both noticed that when our phones are on WiFi instead of 3G/4G we can't get apps to download, we also noticed this happening on the Xoom which is really a problem since we don't have any mobile service on that. Nothing changed in our WiFi configuration between when it was working properly and now. And all devices did it at the same time. what may be affecting the devices to cause this to happen.

General :: Single USB Cable - AB And Multiple Devices?

Any cable is available where you can plug multiple devices into one end of the cable, the other into the computer, and when you install an application from say, Eclipse, it installs it to all the connected devices in one go?

I have about 4 devices running various versions of Android I use for testing, and when I have them all set up together, it gets tedious manually pushing the code from Eclipse to all the devices.
