The previous article introduced the Android uses the microphone to collect and display the analog signal realization method, this kind of collection method is suitable for without IO control, reads the signal simply. If the sensor itself needs to contain a control circuit (for example, the acquisition of blood oxygen signals requires infrared and infra-red emission), then the sensor itself will need to take a piece of the main control IC, in-chip acqu

. NET component, but in fact Microsoft's NET Library does not support Bluetooth, so you must use a third-party control, called inthehand. This article details inthehan D component, http://www.cnblogs.com/procoder/archive/2009/09/22/1571580.html. Since it discusses the idea of implementing file transmission, we will only discuss simple character transmission in this article. Its official website is inthehand.net, and most of the class libraries and met
