Design sketch
The ME91BK01 is a USB Bluetooth Dongle for the MS50SFA-nRF52832 module. It supports switching between master and slave modes by either holding the button for 2 seconds or using commands. Master and slave modes cannot operate simultaneously, and only one-to-one connections are supported. The device defaults to master mode.
In master mode, it can scan and connect to devices via commands. The scan can be configured with broadcast name filters and MAC address filters to identify specific devices. Connections can only be initiated using a designated MAC address.
The adapter communicates with an MCU through the UART interface. In command mode, UART commands can be used to adjust parameters such as scan interval, scan timeout, connection interval, advertising interval, custom advertising data, and baud rate.
It is suitable for developing and testing Nordic-based wireless solutions.
