I'm trying to use Bluetooth for a real-time application, and it's important that the latency and jitter of transmissions are fairly consistent. Mostly, the Mac Bluetooth stack performs well ( < 10 ms latency), but periodically the latency of my transmissions will jump to over 50 ms. This happens approximately every 1.28 seconds. Looking through the Bluetooth specification, I think that the Bluetooth device is entering the PageScan state and delaying my transmissions. Is there a way to temporarily disable a bluetooth device from entering the PageScan mode? In the spec, it mentions that the page scan interval can also be configured to have a maximum of 2.56s (on page 97 of the Bluetooth Specification). This would help, but being able to manually disable and enable page scans would completely solve my problem. In the Bluetooth API, there's the function, IOBluetoothDeviceGetPageScanMode, so I can retrieve the page scan mode for a device, but I don't see any ways to set or disable it. Does anyone have any ideas? Or is there no way to prevent page scans?
