The ME52BS02 is a master-slave module with switchable modes via commands, supporting only one-to-one connections. By default, it operates in master mode, where it can scan and connect to devices by specifying MAC addresses, with optional filters by broadcast name or MAC. The module communicates with an MCU through a UART interface, allowing commands to adjust settings like scan interval, timeout, connection interval, broadcast interval, custom data, and baud rate. In slave mode, the module can broadcast or connect, enabling transparent data transmission between the master and MCU.
