RFCOMM Protocol - Connecting Bluetooth Headset To Computer
Jul 6, 2009
How I can connect my bluetooth headset to my computer(programmatically of course) and read/send audio and button data? I heard that it's something to do with the RFCOMM protocol but it might have been that it's not the RFCOMM protocol.
Today I wan't to ask you how I can make a real radio and here what i mean by real radio:
On the most telephon with touch or untouch screen have fmradio who search radio by using headset for antena. Is thera a way i get a headset and plug it into computer but in witch way i have to write the software.
i have encountered a problem, i want to access the data coming to the computer from the in-built bluetooth module of a computer on windows platform, this data has been sent by a remote bluetooth module say a by an autonomous device (just like a bluetooth mouse connecting to the computer). The to be sent is in the form of numbers and i need these to manipulate on the computer.
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 trying to make an app in VB.NET that pings ip's on a specfic port that are connected to my computer and if it is greater then 500 the person would be blocked from connecting to my computer. How can I do this in VB.NET?
I am making a client/server project where the server can send a String variable to client but for now i'm starting with a simpler code. I was able to code a bit but now i'm having a problem with this UnauthorizedAccessException. It seems that I am not authenticated but i was able to put the admin username and its password. This is my problem.. Here's my code...
When I try to install the application from the files it produces when I follow the prompts from Build - > Publish (Visual Studio 2010) onto another computer, and then run the application on the other computer, it wont connect to the SQL database on the original computer. I've been receiving a timeout error or one which says it can't find the server.I have no idea where to start looking to fix this, both computers are running XP and 4.0 .NET Framework. The computers are linked on the same network.I think my connection string is the culprit, but I don't know how it should be set up to run on multiple computers. Here's my connection string:[code]The connection string works on the application I've installed on the original computer, but not the second computer I've tried installing the application on.My second thought was that it could be the server which is wrong, I've just used the name of my computer for that, is this correct? I thought it may be because all the computers are connected on the network.
So I moved the code to an ASP.Net web app, which is impersonating a service account through the Impersonate section of web.config. The account I am impersonating does not have admin rights on any of the workstations so I put in a username/password into the constructor for the computer entry like so:
Dim deComputer As New DirectoryEntry("WinNT://" + Computername + ",computer", username, password).The username is that of a domain account which has local admin rights on every workstation. If I look at the Username property of the resulting deComputer object I can see that the username matches what I entered.Also if I enter in an invalid password it throws an error, so it is authenticating in some fashion.
However if I now try and add or remove a user from a remote workstation I get a general access denied error. If I add the service account that ASP.Net is using as a local admin on that workstation it will add and remove no problem.So next I tried using the LogonAPI (advapi32.dll ->LogonUser call) to login as the user account that is a local admin on all workstations, impersonated the resulting WindowsIdentitiy and tried running just the original deComputer instantiation. When I do this every property, excepty Path, returns an OLE exception..
Attempting to pull WMI Win32 properties information from a server in a trusted domain using the delegate string listed at bottom and receive the error listed below. The account has fullpermisions on the target server's root and subs WMI namespace and wbemtest connects fine. And all servers are in 2003 Native AD forests and trusted for delgation?

I'm developing a filetransfer app in VB.Net..The sizes of the files vary, but can get up to 10+ GB.I already create a chat app as a test.On the clientside I run this code to connect to the server.[code]Can I also use this to transfer files?I want the app to work through a firewall and stuff.So I think I need the outgoing data on the client to go through port 80. On the server I want to be able to receive the data on another port (E.g. 8888). Is this possible?And final question is. What protocol should I use for this purpose TCP or UDP.
Does anyone know how to create a Application Protocol? For example on a web browser you click a link that goes to "steam://appid/5654" it opens the steam application and the same happens with a bitorrent magnet link. How would you do this in VB.NET?
I'm working on a program that detects any keyboard or mouse activity, and sends a message through the MSN (or Windows Live Messenger) protocol. The mouse and keyboard thing should be fine, but I don't know how to send messages through the MSN protocol.
What I'm trying to do is get the information stored in a little "electronic card" trough a reader connected to my comport. I found a ActiveX protocol to communicate with the reader, but I've no idea how to use it. I'm pretty new to VB.net, and I don't have much experience in coding.So what I'm asking for is how do I use a protocol like this in a VB.net project?
Dim reading As New EmitEpt.EptReading
But that gives me the error "'EmitEpt.EptReadingClass.Friend Sub New()' is not accessible in this context because it is 'Friend'."If I remove "New", then I get the following error: "object reference not set to an instance of an object".
I am trying to work out an ASCII protocol and I have managed to parse everything I need from the transmission, but have not been able to figure out bytes 14-17 and byte 20 of the response. Here is a transmission packet in Hex.
Currently have a program on the market and just did a major update which 100s of people downloaded, the problem is that that update had a major bug which made it crash. So quickly got to work to fix the bug but everytime I connect my software to the FTP database I get this Error Message:
"The underlying connection was closed: The server committed a protocol violation."
I triple checked my code. Everything is right One minute it was working the next minute it wasn't,My buyers are getting very frustrated and I've had to cancel all orders due to this., The bug in the update software which I have now fixed but this other bug to do with protocol violation.I havent tested if its just now my computer that the error messages comes up or it happens on others.I've tried 3 seperate FTP servers and all the same results?
For some reason i am getting this error when I try to upload to my ftp:The underlying connection was closed: The server committed a protocol violation.This happens at the GetRequestStream() portion of the code. here is my
Private Sub FTPUpload(ByVal p_FilePath As String, ByVal p_FTPServer As String, ByVal p_FileNameOnServer As String, _
I don't know how much sense the title makes, but let me give you an example:If you've used Xfire, you may have run across links that allow you to modify things in the program such as your status.This is an example of a status changing link:xfire:status?text=I%20love%20Donkey%20Kong%20Jr.And your status will change to "I love Donkey Kong Jr.
I'm using an Asynchronous Method to send data across the TCP Protocol. For the most part it seems to be working, but recently, I've been getting results that have missing bytes to them. How am I actually able to figure out what's missing on the sender's site and make sure all the data gets to the end? For example: my end client receives 1408 bytes of data when I sent 1532 bytes. I sent an array with a length of 1532 and the client only got 1408.
i got a app that needs to connect to a HID device.but every time i off my PC the pairing of the 2 (PC with the HID device) is gone. is there a way for VB to pair it ?
I desgin an app that encoding text to sms format so you can after that sent this text to your mobile.ok now I want to know how can I send this file by bluetooth from my app
I am developing for my project is "Remote Control Winamp from Mobile with Bluetooth Connection".I have two applications to develop it. Application server with vb.net programming and application client with J2ME.[code]...
im trying to either download a webpage source or get the source and load it into a variable but i keep getting an error:The server committed a protocol violation. ection=ResponseHeader Detail='Content-Length' header value is invalid
