Connect immediately with peripheral in standby mode(Background mode)
by Rushabh 06 Apr '13

06 Apr '13

We are working with Bluetooth accessary that will always be on and advertise packets if application is not connected with device. As per Apple's Bluetooth Design Guidelines Bluetooth accessory should use the recommended advertising interval of 20 ms for at least 30 seconds. As our accessary will keep alway on if we use 20 ms then it is taking too much power. So we are using 1294 ms advertising interval. But with this interval our application is taking almost 10 to 45 seconds to connect with peripheral in stand by mode. Is there any solution to connect peripheral immediately when application is in standby mode and come in a range.

Not sure, but dispatch_main() might not be enough. You might have to actually run the runloop with CFRunLoopRun or something similar. I know that works because I've written a CoreBluetooth command line tool and it works fine.
