I need to connect the Symbian OS device and communicate with files. Is there any api or dll to connect device to do this? I need to back the contacts,photos and other possible files.
Connect how? Packet data, USB, Bluetooth? With Bluetooth there's the OBEX API - it can be used via USB as well, but there are probably more quirks with getting it to work.
If you are using Qt, you can do this with QBlueToothTransferManager.

For a college project, I am hoping to develop a client/server model in C# that will allow the client to stream audio and video from the server. (Android device, streaming from PC)
I understand using tcp sockets and ports, I should be able to (eventually) achieve this over the internet using port forwarding on my router.
Is this possible without port forwarding? How could I, say, have someone install a app on their PC in their phone, and have them communicate? What is required to do so?
I have a long way to go with my studies before I attempt this but I was just hoping for some guidance on what is involved.
you need to have static ip , given by your ISP and just deploy on your IIS or you can use Azure for that - i guess it is just for project
asp.net WebApi has thhe capability to stream data
I'm investigating how the PeerFinder.Start() works on WP8 when I try to connect to an app-to-app scenario via Bluetooth. Anyone knows any method I record and decode this Bluetooth traffic emitted by my devices?
There's no built-in way to record Bluetooth traffic on a WP8 device. I'm aware that's an option on Android, but it's not supported on WP8. I don't see why you'd need to do bluetooth profiling for phone-to-phone communication. If you're trying to do phone-to-device communication you'll need to the communication protocol spec of the packets expected by the device.
I am writing a desktop application that will have to communicate with a windows mobile application in the compact framework 3.5. The communication must occur over the internet between these two applications to send data between them on command if the connection is available.
The system will send messages and objects like Images between device and desktop application and check to see if the desktop can see the device by sending a command and have a timeout on response. (Application will then know that the device is not available).
The mobile device will send a message to the desktop application when online as well that the desktop knows that the mobile is connected(Type of registering for communication)
Can someone please inform me of the best way to follow to accomplish this.
I did some research and found this site is near to something like event based driven communication I would want but do not have the availability of setting up an email on each device.
Battery life and internet open on device is not an issue.
Should I check in on working with the System.Net.Socket class for this type of communication between the two application and if so how will I set up so firewalls will not interfere and have my desktop application be seen over the internet by the mobile application ?
Hope someone can spread some light over this for me, if you have a answer please provide a link so I can read up on it.
your description is something basic. OK, regardless of what TCP/IP communication you decide for (HTTP, sockets) you must always have your internet router forward packages on a specified incoming port to your PC and the firwall must accept these incoming requests.
So, the device will have to send data to the PC and vice versa. So you need a server and a client on the PC and on the PC.
Possibly you can use an already available cloud like Dropbox to exchange files between PC and device.
What are about your skills in socket programming? The main server (PC) must be written multithread to be able to server multiple device client requests.
A simple socket comm is done in my SocketWedge [http://www.hjgode.de/wp/2010/05/27/transmit-data-from-winmo-device-to-pc-socketwedge-and-socketsend/]. A way of multithreaded communication using a web server on the device is available here [http://www.hjgode.de/wp/2012/10/19/windows-mobile-a-simple-web-server-with-extended-features/].
Will SQL with data synchronization be a possible choice?
Can you describe the application in more detail?

I have an embedded system running a web server that will usually be connected to an Ethernet network so users can simply enter the IP address of the device to access it.
However, I also need to make some of the same website functionality avaiable to users of the serial port on the device. It would be nice if I could reuse some of the logic I've developed for the web forms for this.
I am currently using .NET for development on my desktop and my embedded device is Linux based. Is it possible to host website content via a serial port or is there some other means by which I can pull this off?
Just a wild guess: back in the days when you connected by modem to the internet, there was a SLIP protocol: IP over Serial Line. Could you use that to establish an "internet connection" to your device?
There are a few options:
If the server is to be in windows, and you have windows 7 then windows xp mode (1) (2) will allow you to use SLIP so that you can provision over serial as you would to any IP address by mapping the serial port to an IP address.
Alternatively there is a sourceforge project called Contiki which has source code to allow the same if you fancy coding your own (the class is called uIp TCP/IP Stack).
Let me know if this is roughly what you're looking for and I can focus in on your specific requirements if you like:)
Cheers.
The first thing that comes to mind is some sort of LYNX like browser (I don't even know if it exists anymore). Maybe easier would be to just do a simple command line interface? It's linux, so you should just be able to spin up a telnet session pretty easily, right?
I believe you should be able to configure your Linux distribution to point your serial port at a terminal, and have that terminal log in with lynx as the shell.
You might want to follow directions for a Linux serial console (tutorial here) and potentially create a user account with the shell set directly to run lynx. Instruct the login prompt (/etc/issue in the tutorial) with the username and password.
Edit: If you're just looking for some sort of data entry from the console, you could just write a shell script or other program and point that user's shell to that application instead.
You could build a TCP client application on your linux device that will talk to your linux web server and redirect data to serial port, and build a TCP server application for your users that will talk to their serial port and redirect data to some TCP port (like 12345). Then all your users need to do is to set their browser to http://localhost:12345 and connect their PC to linux device via serial port cross over cable.
I have a C# application running on a server, and it needs to copy files out to multiple Windows Mobile 5.0 devices. These devices are connected to the network directly via Ethernet-enabled cradles (so they are not connected to a PC via ActiveSync).
What different options do I have for doing this? I know RAPI can do this, but I'm not sure if it can copy something directly over the network like this. Also, I know RAPI uses ActiveSync DLLs and thus requires ActiveSync to be installed, and we would prefer to avoid doing this if possible.
Is WMI a possibility? Can we use ordinary File.IO if we can somehow get the IP address of each device? Code samples or general knowledge would be most welcome.
Normal file I/O isn't going to work. The devices don't have file sharing OS components, so you can't "browse" to them over the network like you might a PC.
RAPI does use ActiveSync, so not only do you have to have AS installed, the devices must also be actively connected, and ActiveSync only allows one device connection at a time, so it's not going to work for what you want.
My solution for this type of scenario has always been the same. You have to install some sort of "listener" on the devices, whether it is your deployedd app or some form of installer. Sometimes I use an autorun app on an inserted CF/SD card (all depends on your topology).
I usually have that app listen for a UDP broadcast of a "discover" packet from the PC. When they receive it, they in turn UDP broadcast out their IP address and the PC collects those. The PC then sends the files via a TCP socket to the device(s) through the listenner app.
Lately I've been doing all of the device-side pieces via a REST service hosted in Padarn to minimize the amount of comms code on the device I have to write, but you could do it all with Udp/TcpClients without too much difficulty.
