The CMS48SF2V10 serial port module uses the RDF512BT6 chip, and data transmission between the module and the phone can be achieved through UART (serial port) operations. This module is a slave module, featuring command control to modify the broadcast name, adjust the broadcast interval, and change the connection interval. Users can quickly transmit data via Bluetooth using this module.

I. Product Overview The CMS48SF2V10 serial port module utilizes the RDF512BT6 chip, and can be operated via UART (serial port) to achieve module functionality.Data transmission between mobile phones. This module is a downstream module, featuring command control to modify the module's broadcast name, and Adjust broadcast and connection intervals. Users can quickly transmit data via Bluetooth using this module.

Section II: Application Fields

ProductDescription:

If the module serial port connection to the MCU is relatively long, it is recommended to connect an external pull-up resistor.

2. When the MCU sends data to the BLE module, it must pull down pin 14, and then raise pin 14 after the data transmission is complete.

3. Upon entering low power mode, the TX and RX lines remain at a high level. After entering low power mode, the module's serial port is disabled, but the module remains in broadcast mode.Waiting for phone or other host connection.
