FSC-BT1211

FSC-BT1211 is a versatile module supporting BR/EDR/BLE, capable of maintaining one active link in either slave or master mode. It is designed for low energy consumption with support for multiple states and can simultaneously maintain a BR/EDR link and an LE link. The module comes preloaded with Feasycom firmware, making it user-friendly and encapsulated. The firmware allows access to Bluetooth functionalities through simple ASCII commands via a serial interface, functioning similarly to a Bluetooth modem. This makes the FSC-BT1211 an ideal solution for developers looking to integrate Bluetooth technology into their designs.
