I have a Karrimor headset connected to a PC via Bluetooth. After several minutes, the headset gets a delay sometimes 5 seconds or more. I need to restart services to re-sync.
You need to access the configuration options on your PC and change it to always discoverable. Also, if you have the possibility, change the settings so that the device doesn't go into Time Out, regardless if the device is connected or not. Also, this issue might be directly related to the fact that the device is not fully compatible with the Bluetooth feature available on your PC.
