Is it possible to programmatically connect to a bluetooth device. So, without having the user to open the Bluetooth settings and select the device they need to connect to. Note: The device it needs to connect to will always have the same device name.
Yes if you use Core Bluetooth to discover all devices that are discoverable. Then if it matches a name etc then connect to it.
I made a wrapper around Apple's Core Bluetooth framework to make it easier to do these things.

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
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.
i'm an iOs developer and I actually need to make a mac application that use bluetooth framework to connect to another device (not iOS device).
I'm actually showing a modal view showing the connected bluetooth device with IOBluetoothDeviceSelectorController and I get the user choice with [modal getResults] but I don't know how to initiate the connection with the selected device and I can't find a simple way to do it on the mac dev library.
is anyone know a tutorial or sample code that could help me advance in my project?
linkos
The Mac Developer Library has two sample Bluetooth projects; connecting to a health thermometer and connecting to a heart rate monitor. There is also video available of the Advanced Core Bluetooth WWDC 2012 session.
I have 2 iOS devices and an application which starts or connects to a NSNetService.
When both devices have have bluetooth turned on the data stream will automatically be done over the bluetooth interface.
I do not want that, i want both devices to communicate over the WiFi. Is there a way to force a NSNetService to communicate over the WiFi?
Thanks
I don't think there is, I haven't looked into the docs, but I know a ton of games recommend disabling Bluetooth and ensuring WiFi is enabled for local multiplayer.
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.
