Bluetooth-LE-Audio-Auracast-Transmitter

Bluetooth LE Audio (Auracast) Transmitter

Phase: Proof of Concept (Simulation)

---

Overview

This project focuses on the development of a Bluetooth Low Energy (LE) Audio Transmitter supporting the Auracast standard. The current phase is a Proof of Concept (PoC) simulation, demonstrating system functionality without physical hardware implementation. The project uses an NXP NXH3675 transceiver integrated with an Arduino-compatible controller for simulation purposes.

Objectives

• Simulate the transmission of BLE Audio streams using Auracast protocol.
• Validate communication between NXH3675 transceiver and controller firmware.
• Demonstrate Proof of Concept without creating physical hardware.
• Provide a basis for future hardware development and testing.

---

Features (Simulation Phase)

• BLE Audio packet simulation
• Controller-to-transceiver communication over I²C/SPI (simulated)
• Basic audio stream configuration and management
• Logging of simulated data for analysis

---

Hardware (Simulation Reference)

• NXH3675 BLE Audio Transceiver (NXP)
• Arduino-compatible MCU (simulation platform) > Note: Hardware is referenced for simulation purposes; no physical hardware is required in this phase.

---

Software Requirements

• Arduino IDE or PlatformIO
• Python (for simulation scripts)
• Serial Monitor / Logging tool for output verification
• Git (for version control)
