A Basic4Android Wireless Digital I/O App Day 1 Topic Review We Used BluetoothAdmin and Serial Objects to Spawn a Bare Bones Bluetooth Engine. We Used a Digilent WF32 to Create an Embedded Bluetooth-Capable Device. We Attached an AsyncStreams-Based Basic4Android Module to Our Simple Bluetooth Engine and Built a Useful Android App.
