If I connected a Symbian cellphone to PC via usb, is there any way to remotely and programmatically read IMEI.
Nokia Ovi Suite can read it but I didn't see any public APIs.
In most simple Nokia phones you can do this by sending AT+CGSN\r\n on the serial port of the modem of the phone. However if I remember well on smartphones Nokia disabled this feature for some reason. Anyhow it worth a try. Here's a nice tutorial on how to do this: http://www.developer.nokia.com/Community/Wiki/AT_Commands

I have an external device that we need to connect with iPhone by using either Bluetooth or wired connection.
For connecting with Bluetooth we know that if the device has BLE then we can directly communicate with it Using CoreBluetooth Framework.
Otherwise we have to go to get it MFI registered.
Also if we want it to connect it using wired connection then also we have to get it MFI registered.But we have found a cable that connects device with iphone and that cable is MFI registerd. So if i use this cable for connecting iphone to device still do i need to get my device MFI registered??
For configuring this device initially i use desktop (putty). Through LAN cable i insert one end lan cable in device and second end in my computer, then using (putty) serial communication (through COM port) we send some commands to configure it. So, can this be done through iphone also if the device gets connected to iphone through usb cable??if Yes then how???if yes through bluetooth then how??
From the developer of that cable's website
"MFI Certified
All Redpark cables are licensed through Apple’s “Made for iPod” (MFI) program and have earned MFI certification.
Apps developed with our SDK can be deployed under your Apple Enterprise Developers license with no further review or approval from Apple."
Key here is Apple Enterprise Developers license. If you're developing this application for internal release within your company it seems you don't need MFI. To be released on the app store I believe you would still need MFI.
As far as I know to configure your device from the phone rather than through your desktop would require a jailbroken phone. See here for a little info http://www.computerworld.com.au/slideshow/365979/great-iphone-serial-port-hack/?fp=4&fpid=5
I was doing research and couldn't get myself in the right direction so I figured I would ask if it's possible.
For my desktop computer I dont have a mic or a webcam but needed it for some applications.
So I thought to create an app for my Flame that when connected over USB will act as mic and webcam. Is this possible?
Yes you could use webRTC to connect PC & phone and share webcam/mic (either phone->PC or PC->phone). Try Firefox Hello if you want to see how webRTC works.
For example, try http://mozilla.github.io/webrtc-landing/ in both your device and desktop
This is technical question to check the possibilities of the scenario. Is it possible to use Nokia phone's (Lumia, N9, symbain phone, S40) 3G data connection with a Android tablet pc?
Or any way to use phone's 3G data connection with tablet pc?
I have a unlimited data connection for my phone. But I don't use it that much. So I'm planning to use it with the tablet pc.
yep its possible easily if :
1. your tab is rooted
2. your tab supports usb host mode or otg mode (you could either check it on net or download usb host diagnostics) (just click start diagnostic)
procedure
Downoad ppp widget
configure your apn according to pc suite settings
then plug in your phone via usb on nokia pc suite mode
now wait 10s and click connect
you are now done
(pls switch your wifi off as ppp widget creates virual wifi for your tab)
any inquiries contsct rld0989#gmail.com (don't be rest less I only check my gmail once a day)
Yes, it's possible to use your phone as a modem, connected to the tablet via a USB cable, as long as you have
(1) an APN from your network operator to make a data connection via their network, and
(2) suitable device drivers for the phone. On Windows, smartphones are plug and play, but I don't have any experience using them with Android.
On the tablet, you also need some software to control the modem - something like the Mobile Broadband Connect 3.0 application listed on here
You can write a simple connection app yourself using the Android Telephony Manager.
Alternatively, you could connect manually, using AT commands with a suitable AT command program (in Windows, it would be Hyperterminal). This thread describes a possible equivalent for Android.
Standard AT commands to make a data connection are described in the 3gpp TS27.007 specification.
There are a lot of variations for different manufacturers, but making a simple connect should be possible using the standard commands.
Just as the question states, the goal is to reverse engineer the protocol used by a device.
Let's say you have a webcam, an Arduino and an Arduino USB Host shield. You want to talk to that webcam, from which you don't know the protocol. Can it be done by monitoring USB data packets and by analyzing the driver installed for that device?
It would be a really interesting project.
Thanks in advance.
I often use a serial spy program to look at the conversation between two devices. In windows you can pay for it...

In Linux it's free...

Preferably, this would be a computer connected via cable, but if there's a way to do it over wifi then this would also be useful. I'm wondering if it's possible to send messages between them?
Or if i had a mac app and an iPhone app, could I communicate between them over wifi or a usb connection, rather than using a server or something?
Connecting over WiFi is possible, cable connection however isn't possible (certainly not in the documented API) unless the phone is jailbroken.
For wifi you're just going to connect to a TCP/IP host/socket. Have a look at CocoaAsyncSocket. The computer would need to be hosting some sort of server software. This is how iTunes Remote and AirMouse work.
There are some "permitted" (non-cracked phone) ways to send data to the iPhone from a device that's physically plugged in. There are several barcode readers - like the Linēa-pro used in US Apple stores - and magstripe readers for credit cards (e.g., the Macally Quikswipe) that can send limited amounts of data to/from the iPhone.
If your computer is a small embedded device and your data requirements are meager, it may be possible.
