Android :: Bluetooth / Serial Port Profile
Apr 21, 2009
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?

I may be doing some Blue tooth Serial Port programming work for a client and I'm just looking for some tips in determining complexity/ workload. The work is similar to reading from a blue tooth GPS (not making the phone a blue tooth GPS), but it is some custom hardware, so not exact. Here's what (I think) I know so far: I will need to pair devices with a Serial Port Profile. I need to connect using a Bloodsucker which works on Android 2x -I don't know yet if the Android I will be a server or a client in this scenario. I will open an InputStream (no output stream needed) and have a thread continually blocking for input I believe "BluetoothChat" is the best example to start with. What I would want to know. - Are there devices/manufacturers who block the blue tooth serial port, trying to block tethering or something like that? (-I've seen posts here that imply that, but I don't see a bunch of comments like "Doesn't work on my @#$$" in Blue tooth GPS Providers in the market). -Are there going to be hardware specific oddities, or can I develop with my Nexus One and just hope it works on everything else? -Is pairing something that will require a lot of education for the users, and would a good app try to initiate this inside their app, or just assume it is already done. -Is Blue tooth programming going to be my worst nightmare, like it sometimes was on Windows Mobile, or smoother than I could ever hope?

I'm working on an undergraduate level senior design project with the HTC Sprint Hero. We want to connect a device that constantly sends a serial string of data. Does anyone have any hints, tricks, or shortcuts to be able to read a serial string from the USB port and save it on the phone? I know there is not a really simple way but I'm no where near an expert in programming and wanted to see if anyone has come across anything that might help.

I am trying to figure out if there is any way by which I can access any USB device which is connected to my Android phone's USB port and read data off it? For ex. Can I connect a camera to my phone and pull pictures out of it? I know that we need a HOST-DEVICE configuration to be able to do that... have tried doing this on other devices before picking up my android phone.. thought there would be an easier way to get this done. now, when I connect my phone to a digital picture frame, I can see on the phone that it identifies the USB device it is connected to and goes into a USB mass storage mode. What I want to know is if after this, I can read data from the frame or send data to it. I want to write an app that pulls data over USB and stores it into the phone memory.

I thought it would be quite easy to develop a bluetooth application on Android, but it looks like the support is very bad. While pairing works, my Nexus One with Android 2.1 can't connect to the PC. It's the same in Windows and Ubuntu. I used on my Desktop computer, in Windows, Hyperterminal and waited on an incoming bluetooth com-port. I searched already a bit, Maybe this:
http://code.google.com/p/backport-android-bluetooth/
or this library:

I'm very new to the Android platform, but i was hoping to write a quick and neat little android app which will receive data from blue tooth and to graph the data. I'm trying to use a LM Technologies LM049 blue tooth adapter to send serial data to my HTC Dersire 2.1 android handset. At the moment i'm trying to just prove i can send ascii characters to the phone. Not quite sure where to begin.

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 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.

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 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?

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....

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

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've had an inquiry about whether my Android app can interface with a serial device via USB cable. Before I invest too much time in this path, I'd like to know: Is this even possible? Some previous threads indicate Android won't do host USB. Would it require root access and/or the NDK? Would it be better to advise the potential client to look for a serial blue tooth adapter? I can see that there is a Blue tooth Sock class which may do the job.

Iam using a command: adb devices
and get this:
C:>adb devices
List of devices attached
HT9CTP820385 device
My question is: where this serial number comes from? Does it burned on flash of device one time during a manufectoring or adb drivers assignees it dynamically or it comes with release that is burned on device?

I would like to be able to generate unique serial numbers for each Android device for use in unlocking an application. How could I do this? EDIT: The reason is I want to revamp a paid application and provide users who have paid for the old version, which will have a different package name, a way to obtain the full version by downloading an unlikable free version of the application. I would push an update to the old version that would generate and display the code that they could enter to turn the Free version into a fully functional version.
