FSC‑BT2054RI is a highly integrated Bluetooth 5.3 dual‑mode transceiver module powered by the Realtek RTL8761CTV chipset. It supports simultaneous operation of BR/EDR and LE links, allowing classic Bluetooth and BLE connections to be active at the same time. The module can be configured as either a master or a slave, and supports low‑power states for energy‑efficient operation.
Communication between the host and module is realized via the UART interface, while the FeasyBlue Bluetooth stack provides simple API functions for full control over audio and data transmission. Native support for LE Audio (including Auracast™) and classic audio profiles such as HFP, А2ДП, and AVRCP ensures flexible wireless connectivity across a wide range of use cases.
Preloaded with Feasycom’s powerful and user‑friendly firmware, FSC‑BT2054RI enables developers to quickly integrate robust Bluetooth functionality into their designs with minimal development effort.
