On sending data over bluetooth from PC to my mobile(N73), the Input Stream seems to hang up.InputStream is derived from StreamConnection.Does the InputStream have an internal buffer that needs to be emptied while reading large chunks of data?Data is being received in chunks of 10Kb to 15Kb range, and the reading stops after receiving the 3rd chunk.

I am trying to create a client server application. Server side is vb.net program which runs in my computer and listens for commands. Client side is J2ME application which is in my mobile that will send commands.
I have a Bluetooth dongle for my computer and I am going to use Bluetooth as the medium. Wifi is not supported by my mobile.
I know basics of VB.Net(using VB2010). And I have Oracle's J2ME SDK installed in my computer and I have created small(simple applications) applications using it.
So, I have searched in Google. But most of the results are confusing. Today I found Wireless Communication Library .NET Edition. But documentation is very poor. So I don't know in between things, that is connection establishment. But I can code how to execute when each command is received at both sides.
I am only pasting what I feel is relevant to this error but if you deem necessary I will paste the w hole code,software used- sqlserver 2005 express, VS 2008 express - language vb.netlittle extra info is added at the end of this code

is it possible to communicate with a bluetooth device? I have a fairly simple heart rate monitor which has a USB stick, which connects wirelessly to the monitor.
It utilizes a serial port (COM3), where I can communicate with it. I've tried all sorts of data formats to parse the incoming bytes, from ASCII to INT32 to string... Nothing.
How to read in data from an arduino bluetooth microcontroller? I am new to microcontrollers and I have limited VB experience.

View 8 RepliesTrying to read data through the virtual COM port created by bluetooth.
The original console program (and the trimmed version below) was designed to read data from serial port COM1 and output the data to notepad. The program works; hook the bar code reader to COM1, activate bar code reader, swipe card, bar code reader beeps, data input collected from COM1 and sent out to notepad.
The problem: Bluetooth is wanted instead of serial cable.
We disconnected the serial cable, we connected a USB bluetooth receiving device onto the XP. XP installed the bluetooth device drivers 'Generic Bluetooth Radio' and 'MS Bluetooth Enumerator'. Bluetooth detected the bar code reader device and created COM5 outgoing SPP slave and created COM6 incoming.
But now; activate bar code reader, swipe card, bar code reader beeps, NO data input collected from COM5.
