HI, I am using Xamarin to build a mobile app that will print out the label via connected Bluetooth device (ZQ320). After the inactivity timeout, the connection seems like broken when I wake up the ZQ320 with long press the power button on the device. It is really frustrated that I need to rebuild the connection again and wait for few minutes. My question is how can I wake up the ZQ320 programmatically and resume the previous connection so that I can continue printing without rebuilding the connection between the mobile and the printer? Appreciate for any comment.
