MS46SF1 is a module with Bluetooth slave device firmware designed using the nRF52805 chip. It has broadcast and connection status, and uses the UART interface to transparently transmit data between the main devices such as mobile phones/tablets and the MCU.

Bluetooth functionality can be added to the product without the need for Bluetooth develop?ment, providing convenience for product development.

The device broadcast communicates with the MCU through the UART interface. In broadcast mode, the MCU can set and view the module's broadcast name in command format, set custom data, modify parameters such as broadcast interval and connection interval through the UART interface.

When a host connects to a device through Bluetooth, the device will act as a bridge between the host and the MCU for transparent data transmission.
