My friend is designing a pointing device which connects to the computer with Bluetooth and I want to know how to create software or drivers in order operate it like a mouse. if guys know anything about this, please help me out.
Bluetooth is a wireless protocol specification (thousand pages) A lot of pointing devices use a proprietary wireless protocol. To do this, purchase a reference kit from a company like Cypress semiconductor. This kit will contains hardware, software, and firmware sample code and I/O chips. Way more than I can mention here. Texas Instruments and Microchip have Bluetooth/802.15.4 kits too. Used zigbee wireless kits are on Ebay. Hope that helps...

I have done some research on core bluetooth framework. Successfully setup discovery of peripheral of other iPhone, connect, discovered services and characteristics and write some values. All went well. Surprisingly come to know there is apple MIFI program (need to research on it).
In excitement I ordered iPhoneSE, HC-05 bluetooth module, Arduino Builder's Kit R2 with original Arduino UNO. It took some days/wasted in shipment and decent amount and now it's not working.
I write proper set up/initialization for peripheral and central classes, adopted delegates and I think it's all correct. However I am not able to connect to HC-05 bluetooth module.
Observations:
On a Android device i turned on bluetooth in device settings, HC-05
was able to be discovered, enter 0000/1234 (password as per
documentation). And yes i was able to connect it. It means HC-05 is
not malfunctioning.
On a iPhoneSE iOS v11.0, Setting -> turn on bluetooth. But HC-05 is
not discoverable.
I simply want to be successfully discover and connect to HC-05 module using BLE technology. Then with delegate methods look up services/characteristics and then try to on/off led.
I can provide more info and background if needed.
I need some help and direction so that I can purchase the correct bluetooth module which connect to iPhone, and I am sure I can do it.
Thanks.
To answer above question-
HC-05 will not connect iPhone. Because HC_05 is not bluetooth low energy.
I have used AT-09 from amazon.
I have written complete article how I achieved it here, and challanges I faced with solution.
The HC-05 isn't compatible with iOS.
This is because Apple uses MFi Licensing Program and HC-05 is not licensed.
To get things working go for a module supporting minimal BT Version V4.0 BLE. Even better, BT Version: V4.2 BLE & V5.0 (better range and larger packet-size), if iOS (v11.0) supports it.
I am not going to recommend a specific model, that's what Google is for.
Apple devices under the MFi licensing scheme only support limited profiles.
HC-05 is based on Bluetooth 2.0. What will work for Apple mobile devices (iPhone, iPad) will be those modules that utilise Bluetooth 4.0 or Bluetooth Low Energy (BLE).
Im doing a research about connectivity.
But Im still wondering what the costs are for implementing a bluetooth chip or wifi module in a device that will allow me to connect to the iPhone. Does somebody here know something about these costs?
A website with these modules is also sufficient.
Thanks in advance
They're both relatively cheap. However, bluetooth is very limited when it comes to connectivity due to the half-ass job Apple did in implementing the required protocols to do something constructive with it. Wifi is limited because you have to establish some sort of AdHoc network (unless you have a wireless router in between), but after that you are basically limitless (though you have to do a lot of manual labor when it comes to implementing something useful.)
I have a project where I need my iPhone to communicate with an Arduino. Bluetooth seems like the best option for the communication. How should I program my iPhone (what framework?) to communicate with the Bluetooth Mate or do Apple's restrictions prevent this? Is it possible with a jailbroken iPhone? Is there a better way other than Bluetooth? Sample code would be helpful.
Thanks in advance
Actually you can make it happen now without Jailbreaking or MFi enrollment.
Take a look ate Bluetooth 4.0 in newer iOS devices and Arduino BT 4.0 shield.
This might help: http://blog.makezine.com/2012/03/19/bluetooth-4-0-from-arduino-to-iphone-no-jailbreaking-no-mfi/
Meanwhile there is an Arduino shield available from Seeedstudio: Bluetooth Low Energy Shield
Devices following the Bluetooth 4.0 specification can be accessed by all iPhone/iPad models with a Bluetooth 4.0 chip inside (currently iPhone 4S, 5 and iPad 3) running with iOS 6. You no longer need to be part of the MFI program or jailbreak the device for most purposes. Use the Core Bluetooth Framework that's also discussed in the WWDC 2012 videos Core Bluetooth 101 (Core OS) and Advanced Core Bluetooth (Core OS).
It's been a while since I was in contact with embedded bluetooth-to-iphone devices, but as far as I remember you have to buy authentication chips from apple.
Apple MFi
But as jailbreak is an option this might work. But I never tried this, because I once was in possession of some authentication chips.
I found btstack with a quick googling, maybe it's helpful.
Try instaling bluetoth iBlueNova, and it will comunicate with each device.
Yes, the best way to do this would be to use Blynk. Make an account, copy the example code, and get started with the Blynk app!
Apple's OS app sandbox prevents generic (Classic non-BLE) Bluetooth serial data comm on stock OS devices, except for a few companies registered in their MFi program.
The most reliable and possibly the easiest solution is to the use the Arduino Ethernet shield with a physical network connection to your WiFi router. The Arduino would host web pages or respond directly to http that did your work for you.
No jailbreaking, no BT programming, no serial com port stuff. Just regular old web pages. Sweet stuff.
The simplest solution would be to navigate with any browser on your network, including your iPhone, to your Arduino and issues commands.
Example:
http://192.168.1.101/?1
192.168.1.101 = the IP of your Arduino
?1 would mean PIN13 pulled high (i.e. turn on the LED)
Your code would be something like:
EthernetClient client = server.available();
while (client.connected())
{
if (client.available())
{
char cVar = client.read();
if (cVar != '?') return;
Serial.Print(cVar)
if (cVar == '1') digitalWrite(13, HIGH); //turn on the led
}
}
That code is quick and dirty so don't hold it against me!
Let me know what you decide and how it works out. I need to go read up on http://blog.makezine.com/2012/03/19/bluetooth-4-0-from-arduino-to-iphone-no-jailbreaking-no-mfi/
Thanks for that link ygbr!
What is the best way to realize wireless communication between an embedded system (based on an AVR controller) and the iPhone? I think there are only two options: either WiFi or BlueTooth. The range is not really a problem, since both devices should stay in the same room.
I have no idea, if there are any useful WiFi boards that can be connected to an AVR based microcontroller system (or any small microcontroller), any hints would be highly welcome.
I guess the better solution would be BlueTooth, but there is also the problem: which BlueTooth board is best suited for attachment to an AVR system, and is it possible to use the iPhone BlueTooth stack for (serial) communication over BlueTooth with the AVR device.
I hope that somebody already realized such a system and can give some helpful tips...
You can get modules for both WiFi and Bluetooth that will connect to an embedded system through a UART interface, however a WiFi module will have far more processing power than your AVR microcontroller, often with spare capacity and I/O to execute additional user code, so connecting one to an AVR maybe somewhat redundant in many cases.
Bluetooth modules are simpler, less expensive, and the data-rate is better matched to the AVR's capabilities. For example these Parani modules. I have used them between an embedded system and a Laptop PC's Bluetooth, so given appropriate communications software, there is no technical reason why it could not be used with an iPhone I think. However this may be the flaw, on the PC the device was recognised as a virtual serial port, I don't know whether iPhone supports 'legacy' communications in quite the same way.
For comparison, a WiFi solution
From what I know, BlueTooth is very limited on the iPhone: There is only very few BlueTooth-Profiles implemented, and - even if they can be extended with a jailbroken iPhone - I doubt this is easy to use from the application layer.
On the other side, transferring via WiFi requires a lot of processing power and memory since much more things have to be implemented before you can even start transferring data: 802.11, cdma/ca, arp, tcp. That's a big task.
Is it an option to build a hardware extension to the iPhone ? You might be able to get the serial connection and power out of the dock connector. Then even ZigBee could be very helpful.
Here's an article you might find helpful. I would lean toward a WiFi solution just because of the added flexibility available.

Some of the other people at the office have done AVR <- Bluetooth -> Symbian and AVR <- Bluetooth -> PC solutions without trouble. There is lots of info, reference designs and source available. I have no idea of how hard it would be to use Bluetooth on Iphone.
The exact module is probability also not important as long as it got some type of serial interface (I2C,SPI) to interface to the AVR and some source code show how to use the module.
Is it an 8-bit or 32-bit AVR? For the AVR32 processors there's support
for WiFi in the Atmel 1.5.0 Software Framework using SD-card-mounted
WiFi modules from HD Wireless (http://www.hd-wireless.se), including
an IP stack (lwIP). Be aware that you need Ad-Hoc (IBSS) support to
connect directly to the iPhone.
There is WiSnap kit. It can connect directly to a standard RS232 interface or through the TTL UART interface to embedded processors. We are planning to use it in our project. It also has Ad-Hoc support.
There are some usage examples and an iPhone application for connection setup.

What are you trying to communicate between your AVR and the Iphone? The Iphone is made for the web along with everything apple (which AVR's are decidedly not). So what works well is an embedded device that exposes a web-interface. Like the Transmission bittorrent client on Linux. Also nowadays many low-power small form-factor linux platforms exist that will allow you to do this.
For instance Gumstix has an ARM based platform that runs linux and includes WiFi (Overo Fire).
I am looking for a way to establish a wireless connection between an iPhone and a desktop client. Gamekit looks promising but all the examples / documentation only explain iPhone to iPhone.
Are there examples / documentation for an Gamekit peer on the desktop (cocoa or java)?
What are the alternatives without doing to much low level socket programming?
The iPhone emulator does not run these bluetooth p2p connections. Hence, it can only be tested with real hardware.
It is a little confusing because the GKSession reference talks only about being a way to connect peers over bluetooth, while the GKPeerPickerController states "can be configured to select between Bluetooth and Internet connections." However there's a clear note there that they're not really going to help you with internet based connections.
This is unfortunately a non-answer, but...
GameKit is an abstraction of the bluetooth and wifi networking layers, allowing a specific set of protocols for communication between two devices -- to communicate with a desktop client, you would need to replicate all of the GameKit functionality on the desktop, since there is no comparable API on the desktop. This would not be a simple undertaking.
I would highly suggest developing something over bonjour, as #Jordan suggested. Bill Dudney's project (blog article). It's a great place to start.
Citing Game Kit Framework Reference's Features paragraph:
Peer-to-peer connectivity allows your game to create an ad hoc Bluetooth or wireless network between multiple iPhones in the same local area. Although designed with games in mind, this network is useful for any type of data exchange among users of your app. For example, an app could use peer-to-peer connectivity to share electronic business cards or other data. This functionality is only available on iOS. You can also get the same functionality using Game Center.
