The BM20/23 stereo audio module is a Bluetooth v5.0 (BDR/EDR) audio module for designers to add wireless audioThe BM20/23 stereo audio module is a Bluetooth v5.0 (BDR/EDR) audio module for designers to add wireless audioand voice applications to their products. This Bluetooth SIG-certified module provides a complete wireless solutionwith Bluetooth stack, integrated antenna, and worldwide radio certifications in a compact surface mount package.This stereo module contains a built-in Li-Ion charger and a digital audio interface (BM23). It supports HSP, HFP, SPP,A2DP, and AVRCP profiles. Both AAC and SBC Codecs are supported for A2DP.
Note: The customers must connect their own external analog Codec/DSP/amplifier and MCU for audio output.
Audio processor:
• Support 64 Kbps A-Law, μ-Law PCM format/Continuous Variable Slope Delta Modulation (CVSD) for SCO
• Support 64 Kbps A-Law, μ-Law PCM format/Continuous Variable Slope Delta Modulation (CVSD) for SCOChannel Operation
• Noise Reduction (NR) and Acoustic Echo Cancellation (ACE)
• Sub-Band Coding (SBC) and Optional Advanced Audio Coding (AAC) Decoding
• Packet Loss Concealment (PLC)
• Four Languages (Chinese/ English/ Spanish/ French) Voice Prompts Support (20 events for each language)using the IS20XXS_UI tool
• Serial Copy Management System (SCMS-T) Content Protection
