Make Bluetooth data transfer solutions more streamlined and applicable
According to the different application needs of customers, Realtek provides two data transfer solutions: BLE data transfer and dual-mode Bluetooth data transfer. The Bluetooth chip integrates a complete Bluetooth protocol stack and rich application instructions. The main MCU is connected to the Bluetooth chip through UART, and uses application instructions to configure the basic connection parameters of the Bluetooth chip to expand the Bluetooth transparent transmission interface.
Practical Application Case
Dual-mode Bluetooth Data Transfer Solution:
Dual-mode Bluetooth Data Transfer Solution Feature
• GATT and SPP profiles inside;
• Communicate with external MCU by UART;
• Integrates 32K oscillator for power management.
• Baud rate up to 4Mbps;
• Default baud rate 115.2kbps;
• UART I/F (H4 supported);
• Hardware flow control supported.
Full-featured dashboard SDK, with supporting mobile phone APP engineering, which greatly reduces customer's development workload and accelerates the implementation of project.
Single-mode Bluetooth Data Transfer Solution:
Single-mode Bluetooth Data Transfer Solution Feature
• GATT profiles inside;
• Communicate with external MCU by UART;
• Integrates 32K oscillator for power management.
Full-featured dashboard SDK, with supporting mobile phone APP engineering, which greatly reduces customer's development workload and accelerates the implementation of project.
