Setup and Code the Remote DeviceStep 1: Define the WF32 LEDs 5 and 6.
Step 2: Code the LED Command Handler.
TRISFCLR = 0x0001; //WF32 RF0 = OUTPUT - LED5 TRISGCLR = 0x0040; //WF32 RG6 = OUTPUT - LED6
if(CharInQueue()) //print received character {
biteIn = recvchar();switch(biteIn)
{ case 0x35: LATFINV = 0x0001; //LED5 break; case 0x36: LATGINV = 0x0040; //LED6 break; } }
This code is added to the main function of the EDTP Embedded Bluetooth Driver.

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.
