FSC-BT836B is a dual-mode Bluetooth 5.3 high-speed data transceiving SoC module, supports profiles such as SPP, HID, GATT, and ATT. When connected to devices using the Android operating system via the SPP profile, it supports a maximum data transfer rate of 80KB/s. For devices using the iOS system and connected via the GATT profile, it supports a maximum data transfer rate of 65KB/s. It also supports both master and slave roles. The module comes with powerful and easy-to-use firmware, developers can use simple UART AT commands to integrate Bluetooth audio functions, with the support of FeasBlue and Serial Assistant multi-platform apps, development gets simplied further.
