The following sections will show how to modify the ATmega328P Xplained Mini to connect the ATWINC1500 Xplained Pro and I/O1 Xplained Pro extension wings. The example project and Android application will also be detailed.
The example project will transmit UDP (User Datagram Protocol) packets at given intervals for the Xplained Mini to be discovered by the Android application. The application can then connect via TCP (Transmission Control Protocl) and send a message to toggle the LED on the I/O1 Xplained Pro.
