 Sound Buddy is only at its first stages of development. At the end of this project cycle, we have Sound Buddy demoing its ability to send data over Nordic and play music on one or multiple receiver devices.

 Before soldering the components on the PCB, we tested on a prototype board to make sure the design was functioning correctly. We found some connection issues and resolved it appropriately on the PCB when the components were soldered.

 The receiver board also initializes the necessary device drivers (SPI/SSP & Nordic wireless) and run FreeRTOS. It also depends primarily on two tasks. One task to wait for the RX FIFO to receive a data packet and the send task to handle the writing to the SD card. As soon as the MP3 file is completely loaded into the SD card, it waits for a command to be sent to control the MP3 decoder functionality.
