This Bluetooth Dual Mode (BTDM) Software Stack is the most mature and widely used licensed SW Stack in the market for Bluetooth Audio (Dual Mode) and IOT (Low Energy) products today. The stack has been licensed by many companies including the Bluetooth Special Interest Group (BT SIG) for use in the Bluetooth Profile Tuning Suite (PTS). Customers use this Bluetooth SW Stack in both Audio Dual Mode (DM) & Low Energy (LE) v5.4 SoCs, maintaining a common SW code base across all products, enabling common customer support, and commonality of features, through a simple compiler option.
This Bluetooth Dual Mode SW Stack implements the complete Bluetooth v5.4 LE Audio Profiles and Services including but not limited to HAP, TMAP, Generic Audio Framework (MCP, CCP), Common Audio Profile (VCP, AICS), BAP, etc.
The SW is equipped with Advanced Codec Support for Audio Streaming using A2DP, LC3, SBC, mSBC & 3rd Party codecs (MP3, AAC, etc.). The Bluetooth Dual Mode Protocol Stack SW & Profiles have been optimized for TWS applications supporting different TWS implementations both the TWS relay method & TWS Sniffing method. The Software enables customers to reduce the market risk of integrating Bluetooth into the product while accelerating the development cycle.
The large base of customers is testimony to the IP’s high quality, proven reliability, functionality, and portability as per the adopted Bluetooth.
