core-bluetooth

My objective here is to create a connection between a device running iOS to a device running Mac OS X , via bluetooth. I know that I might be able to use CoreBluetooth for this but I don't understand how since I don't see a method to setup a service on the iOS device and broadcast it as an available service for a device running Mac OS X . In other words, I simply want to setup a connection to get the iOS device to send data to the Mac OS X device . Also, how would I go about to specify how to setup properties of the service. I've tried researching this stuff but most of the documentation makes

I'm working on the app that will connect with a smart device via BLE and communicate with it. The question is: In what queue is the best practice to handle bluetooth events? I've read a lot of tutorials and in all of them I found this: centralManager = CBCentralManager(delegate: self, queue: nil) They choose to handle bluetooth events in main queue ( queue: nil ), but I suppose that it's not good practice. Because it could be a lot of queries send to peripheral device from central and a lot of answers send from peripheral to central. I assume this might be the reason of the app working slowly

I want to write a tracking application, which reacts/record when users get in a car and phone automatically pair with Bluetooth hands free. I need also Id of the hands free device. On Android it is easy, using Broadcast Receiver your app listen to broadcasts that device had been paired with phone. It is working even after phone had been restarted and App did not run after restart. Is it possible on iOS(7+) ? You can do it by reading the "Performing Long-Term Actions in the Background" part of this docs Essentially, using state restoration, the system takes note of what your app was doing when

I am implementing a BLE central device on the iPhone, using as peripheral a custom BLE device developed (whose firmware has been written by a colleague). The peripheral for some operation will return a BLE error code, conforming to the standard Bluetooth ATT error codes as defined in BLE specifications. On the iPhone side, where I'm using the CoreBluetooth stack to develop the central device, I am notified of such errors on the debugger output window of xCode as: CoreBluetooth[WARNING] Unknown error: XX and then I receive in the callbacks a CBError* object. My problem is that the CBError*

I have a strange issue. I am developing an app in which I am sending Chunks in 20-20 bytes. . Everything is working fine. When I am sending Bytes data from iOS 8 to iOS 8 device it take around 4-5 second to transfer from one device to another, but my problem is when I am sending Bytes data from iOs 7.1 to iOs 8 or reverse, It take around 17-20 seconds to transfer the data from one device to any device. Why it's taking too much time in iOS 7.1 to iOS 8 or reverse? Manthan Try to look at some of the links below. That might help you. Link1 Link2 This is just a reference of links that might help
