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?

Is there a simple way to activate/deactivate bluetooth without having some dialog popup requesting the user's permission every time? I have an app that plays music (it's actually part of a scheduled alarm). I want to play music through some bluetooth speakers I have already paired the phone with, but I don't want bluetooth to run while I am not using that app or after the app has shut down -- I want to reduce any unnecessary load on the battery.

I wanted to try and connect to an bluetooth device using the HID profile using an android phone. The phone I'll be using is the vibrant and according to samsung it doesn't support the HID Profile ( http://ars.samsung.com/customer/usa/jsp/faqs/faqs_view_us.jsp?SITE_ID=22&PG_ID=2&PROD_SUB_ID=557&PROD_ID=560&AT_ID=281257 ).
Now my question is this, where does this "profile" reside? Is it on the hardware level or on the software level ( I assume the latter from other sources that I have read ). And if it is the latter, can HID implementation be created using RFCOMM communication over bluetooth (this is the only seemingly viable method I can see in the android bluetooth API).
I just want to make sure I understand the technology before I try and implement something that may not be possible.

I was getting ready to connect my Motorola Droid bluetooth with my car. However, when I go to Wireless and Network Settings my Bluetooth and Bluetooth Settings options are inactive. Clicking on them does nothing. Any ideas on what's going on?

I want to develop an application for input device(bluetooth). I would like to use HID profile or SPP. But Android SDK support only A2DP and AVCRP profile. I'll have to wait until the next version is released. I have one question. I think A2DP, AVCRP profile use SPP. is correct? If so, we can use SPP instead of A~~ profiles? I don't know bluetooth api.

I realize that the Blue tooth API is subject to change over time and that the only available profiles are A2DP and AVCRP, but I am really interested about the options I have to develop an application using the Serial Port Profile. I don't really care if the API will later change, this application is meant to be used only by me (I am trying to communicate to a mirocontroller using Blue tooth and the only supported profiles are SPP and GAP). I am going through the /core/java/android/blue tooth/ classes at the moment but I don't see anything that refers to the SPP or otherwise. I am willing to invest time to learn and write a SPP implementation, provided I have someone to guide me. This is valuable to me because I am doing this project as a final year project so I'm not exactly waiting for someone else to do my work. In conclusion, does anyone have any suggestions on where I could start looking and studying to be able to use the SPP in an application?

The roadmap for cupcake states that it now supports the Bluetooth A2DP & AVRCP profiles. Since the Bluetooth API was ripped out of 1.0 does that mean that these are the only profiles supported? Or are there any other profiles currently supported?

I read somewhere that the Nexus One supported the SPP profile but now this page seems to contradict that : http://www.google.com/support/android/bin/static.py?page=guide.cs&gui....

I read the thread at http://androidforums.com/support-troubleshooting-incredible/85052-bluetooth-battery-consumption.html and noticed everyone saying that BT significantly drains your battery when on but not in use. It seems like a huge pain to have to press an icon everytime I get in the car and everytime I leave to turn it back on, especially since I don't get too many calls while I'm driving. Is there a way to have BT cut on when the car dock app is activated (I have the Motorola car dock app)? And if not, does anyone know if the drain in battery on the DX is significant?

I have an odd problem. When I press and hold the button on my Voyager Pro HD headset, it no longer activates voice dialing. I've tried uninstalling all voice related 3rd party apps; I've deleted the data and cleared the cache on Bluetooth Share, Voice Dialing and Voice Search.
I should add that my phone is a Vivid running 2.3.4 and HTC Sense 3.0.

Does anyone know if the DI has/uses the A2DP Bluetooth profile? I'm looking for a good Bluetooth stereo earbud set and most say they use A2DP. I checked all the literature on the DI that I could find and don't see A2DP listed anywhere. I searched the forums and found some info regarding the Hero and Motorola Droid, but nothing on the DI. I did read where the Hero with Sense UI had some issues with 3rd party apps and A2DP, but that the native Sense UI music app worked fine. Can someone enlighten me on A2DP and the DI please?

A friend wanted to know if he could use his android tablet as a headset, and after some searching it looks like quite a few people would like this.
So I was sondering if this is possible, I am new to Android development and I have been playing around with the Bluetooth samples and cannot seem to figure out how to make other devices see Android as a headset.
So my main question is- Is it possible to make a app that would disguise an android device as a headset so it could receive calls and maybe even dial number?
I would like to clarify if this is even possible with the Android SDK
The main use if i make this app is for people who can't afford the data plan that is required when buying a smartphone from a carrier. So if this person has a small android MID they can pair it with their dumb phone and essentially use their MID as a phone.

Is there any way that I can disable the A2DP Bluetooth profile on my Hero please? I do not want it to be used for one particular connection, my Bury car kit, but do not mind if it is off all the time. I used to be able to do this in WM with a little app called BTMusic - does anybody know of an equivalent in Android please? I have searched the market without success.
I know I can long press on the connection and tell it not to stream media, which switches off A2DP, but I can't make that stick. Next time they pair it is back on again and I then have to go in and manually switch it off again. A pain when all I want to do is get my sat nav speaking to me when I sit in the car!

I use MAP to see texts on my Toyota Camry. It's supposed to be able to read email as well. However, there are times where the MAP settings aren't saving and the look actually changes. In one instance I get this:
With this screen the settings won't save and messages can't be read. If I reset the phone, however, and go back to the MAP settings it will sometimes change to this:
With the setting screen like this, the car can access text messages but not emails. HTC One X using Tapatalk 2

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!

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?

Is there a way to set different bluetooth, screen timeout, and profile settings for each scene on the Evo? I use Pandora and the music player in the car. The problem is my bluetooth headset is set to play media audio so I have to change that every time I get in and out of the car. And I don't want the display shutting off either, so I have to change that every time I get in and out of the car. While I'm at it, is there a way to set a different profile (vibrate, normal, silent) on different Scenes? That's another thing that I find myself manually changing more often than I would like. I'm thinking the "Scenes" feature of Sense would be ideal for this. Just set up the apps you want, the profile settings, display settings, etc, and save that Scene. But I can't make it save any settings other than the wallpaper and widgets/shortuts.Does anyone know how I could go about this? Even is it's not possible in Sense, is there another way to do it?

I am building an indoor application which continuously scans the bluetooth dongles located at different locations in a place like a mall or library.As I move in the mall with android phone in my hand I should be able to get the nearest dongle which I can connect to(Stupid Idea but I want to do something else with this).For this I should be able to continuously scan for the bluetooth devices.

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?

First - let me know if this is not the correct discussion group.
How do you remove a bluetooth device?
Path I'm taking:
- Settings
- Wireless & Networks
- Bluetooth Settings
- Menu
The only option I receive via menu is 'Scan for Devices'

I'm trying to setup bluetooth trusted devices on my Moto X so I don't have to unlock the phone when I'm near my computer, but for some reason, the bluetooth connection keeps disconnecting whenever the phone goes to sleep. I tried using my Jambox as a trusted device, and it worked fine.

Galaxy S f/w 2.1. It doesn't find either of my bluetooth devices - headset and handsfree. My old phone worked fine on both of them.
I enable Bluetooth. The icon goes nice and green. The blue squiggly thing appears in the top bar.
I activate my VisorBlade hands-free device. It beeps and the right lights come on. But no glimmer of recognition from the Galaxy. I go to Settings > Wireless and Network > Bluetooth > Scan Devices. Nothing found.
I switch on my Plantronics Voyager 520 and it beeps and the right lights come on. Phone remains nonchalently aloof. Scan for devices. Nothing doing.
But. My PC finds the phone when I do the Make Device Visible thing.
