Obviously a nice thing about bluetooth is you can wave the sensor around within a 30 or so foot area while your PC sits quietly on your desk processing the data.Īnother idea is you could buy an embedded USB host designed to work with android devices, either an official ADK solution for Android 2.3+ or something community driven like the IOIO board that can use the ADB protocol with older android devices. Using a bluetooth serial connection is certainly a possibility - you can check the supported baud rates and figure out what kind of update rate of packets of however many bytes that can give you, and decide for yourself if that is acceptable. You will need a microcontroller capable of talking SPI or I2C to that sensor chip, and also capable of communicating with the android device. ![]()
