RN52 – Bluetooth Audio Module as Source

RN52SRC v1.00 Firmware Release Notes

The RN52 Bluetooth audio module provides a fully integrated solution for delivering high-quality stereo audio in a small form factor (13.5 x 26 x 2.7mm). It combines a Class 2 Bluetooth radio with an embedded DSP processor, controlled and configured by simple ASCII commands and GPIO. The RN52 module complies with Bluetooth specification version 3.0.

Up to now, the RN52 could only be implemented as a sink, supporting the HFP/HSP, A2DP, AVRCP and SPP stack profiles. With the latest release of the firmware V1.00 for the RN52SRC, the audio module is now also capable to work as a source, for example to build up an audio gateway.

The module supports iAP profile discovery for iPhone® and iPod® Bluetooth accessories. Furthermore the module includes support for codecs such as SBC, aptX®, and AAC. It provides a UART interface, GPIO, stereo speaker outputs, stereo microphone inputs, and a USB port. The RN52 is certified according to FCC, IC and CE.
