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 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?
View 19 Replies View RelatedI 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?
View 6 Replies View RelatedI 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:

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.

Very surprisingly I am not able to transfer (both Send and Receive) any files through BLUETOOTH. This is such a basic function of all mobile. I have tried couple of file managers, Bluetooth Manager but not able to transfer. I have rooted the phone .
I wanted to send an apk to my friend but it says something like not supported filetype and therefore it's automatically rejected and it is not sent in consequence. It's not a problem with my phone but with Samsung i9000 dual core 1.2GHz with mali400. IMO we could fix it by adding a line but I'm not sure which file to edit. Weirdly he's able to send apk's. I can send apk files to everyone but him. His Rom is resurrection remix v4.0.7

View 2 Replies View RelatedHello all, I have a great problem with my XPERIA X10 Mini Pro. I am not able to receive any files from my PC (Vaio, Widows Vista). When ever I try to send a file using Bluetooth I receive an error message (even if mobile is paired with pc). This is the same case with other mobile phones also (not able to receive files from other mobile phones using Bluetooth), and at times my device is not even discovered (Please note that I have made my device discoverable and know that it will remain discoverable for 120 seconds only)
Another problem I have encountered with Bluetooth is that when paired with my laptop the phone automatically answers to incoming calls.
