[2008] Getting Strings From A Bluetooth Com Port?
Jan 9, 2009
i'm currently trying to make a connection between my phone to my PC using vb .net and a program I will build for my phone.my phone should send information (some strings) through the com port, I wrote in google "VB .net bluetooth" and I sew there is a library for vb .net, but I don't think I need that library, can I communicate with a com port without this library? like making a connection with a normal com port?If I'm right, how do I do that? how can I recieve information from the bluetooth com port?

Trying 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.

I've set up two computers, with a null modem serial cable. When trying the connection in two Realterm windows it works ok to send strings.I'm trying to write a simple project that sends the timestring over the same port.One button sends the timestring. I've created one other sub "AppendLabel" that just updates a label.text so I can see what's happening.[code]

I have quite a bit of VB6 experience but now am trying to create my first VB.Net project. The project is very simple - it just needs to send 8-10 character strings from the PC serial port. The problem I'm seeing is that VB.Net is always sending out a 0x0A character after each 'WriteLine' call. Using VB6 it was necessary to manually send out any End Of Line characters. My application requires that no extra EOL characters be sent after the string.

I was trying to play a bit with bluetooth devices but i can't find that much info about it. I'd like to build some sort of program that allowed me to send messages into bluetooth enabled cellphones. The idea was to send messages with tasks/events inside the building. This software would be part of other software such as ERPs or agendas.

I'm migrating from VB6 to VB.NET, in hence my questions below:
I have to write a function that returns array of strings.
How can I initiate it to empty array? I need it since I have to check if it's empty array after it returns from this function.
Is list of arrays better for this purpose? If I use a list - Is it empty when it firstly defined? How can I check it it's empty?

Say I have a List(Of Tag) with Tag being an object. One member of Tag, Tag.Description, is a string, and I want to make a comma-separated concatenation of the Description members.Is there an easier way to do this than to read the Description members into a List(Of String) and then use the Join function?

I am looking at adding in some bluetooth functionality to my vb.net application. I require it to couple with a specified mobile phone (that is found by the app) than to be able to retrieve contact information, phone calls (made and recevied) and images from the phone.
Can anyone tell me what my best approach will be for this? If there are any good third party solutions that will do it? If it is actually doable? Im thinking that it should because im basically mimic'ing what all the new fancy cars do with their bluetooth phone compatibility.
