Typical use case is Audio with a specific Bluetooth Audio profile called A2DP\n    - Bluetooth Low Energy (BLE) : focus on sending bulks of data while optimizing power consumption. Highly popular in IoT\n- Key things to know about Bluetooth Classic (… and Audio)\n    - It takes more than Bluetooth to support Audio : audio products typically are dual mode bluetooth (Classic + BLE) with embedded MCU and DSP for audio processing. This is what Microchip proposes !\n    - A2DP profile could support different music codecs to compress the music files into bit-rates that could then be broadcasted thru Bluetooth\n    - Popular codecs :  low-complexity sub-band codec (SBC), Advanced audio coding (AAC), Sony’s proprietary codecs (LDAC)\n    - Microchip has BM64 solutions supporting SBC, AAC and LDAC.\n    - Microchip has solutions for Stereo and Multi speakers, True Wireless earbuds, headsets and headphones\n\u003c/br\u003e\n\n### Class 1 or Class 2 \u003ca name=\"step1b\"\u003e\u003c/a\u003e\n\nTwo options are proposed to our customers:\n- the BM64 Class 2 module comes with +2 dBm (typical) output power (headset or mono/stereo speaker) (see DSPK firmware) \n- the BM64 Class 1 module comes with +15 dBm (typical) output power to fulfill applications requesting higher range, well suited for \nmulti speaker applications (see MSPK firmware).\n\u003c/br\u003e\n\n\n\n### Stereo or Multi-speaker \u003ca name=\"step1c\"\u003e\u003c/a\u003e\n\nTwo additional options:\u003c/br\u003e\nThe BM64 module can be configured with one of these two firmware versions.\n\n- DSPK Firmware enables A2DP music streaming to one speaker (mono) or two speakers (stereo: mono left and mono right).\n- MSPK Firmware enables A2DP music streaming to more than two speakers from one audio source such as a smartphone.\nMSPK refers also to Microchip Wireless Concert Technology (WCT).\n\u003c/br\u003e\n\n## Overview of our Solutions \u003ca name=\"step2\"\u003e\u003c/a\u003e\n\n### Select a speaker
