T2M Bluetooth BT Dual Mode v5.4 Software Stack & Profiles IP

BT Dual Mode v5.4 Software Stack & Profiles IP

Description and Features

This Bluetooth Dual Mode SW Stack is the most mature and widely used licensed Bluetooth SW Stack in Bluetooth Audio (Dual Mode) and IOT (Low Energy) products today. It has been licensed by many companies including the Bluetooth Special Interest Group (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) v5.3 SoCs, maintaining a common SW code base across all products, enabling common customer support, commonality of features, through a simple compiler option. This Bluetooth Dual Mode SW Stack implements the complete Bluetooth v5.3 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 TWS relay method & TWS Sniffing based method. The Software enables customer to reduce market risk of integrating Bluetooth in the product while accelerating the development cycle.

The large base of customers is testimony of the IP’s high quality, proven reliability, functionality and portability as per the adopted Bluetooth.
