The AT command mode and throughput mode are two different modes of operation for Bluetooth modules. The AT command mode is a master-slave response mode where the main controller sends AT commands to the Bluetooth module through the serial port to control and configure it. Such as the device’s baud rate, Bluetooth name, pairing mode, and other parameters. The Bluetooth module then responds to the main controller through the serial port. In contrast, the throughput mode is a transparent transmission mode where data is transmitted through the Bluetooth module without requiring specific commands. The main controller sends data to the Bluetooth module through the serial port, which is then transmitted to the platform. The platform can also send data to the Bluetooth module, which is then transmitted to the main controller.
It is important to note that in throughput mode, it is still necessary to configure the Bluetooth module by sending related AT commands through the main controller to enter transparent transmission mode, set platform addresses, and other parameters. Additionally, it is recommended to increase the data length and verification to prevent packet loss. In both modes, the Bluetooth module is responsible for transmitting data, but in throughput mode, it does not process the transmitted data and only transmits it to the destination node. In this mode, the Bluetooth module will typically use a different packet format and may employ various optimization techniques to improve data transfer rates. The specific details of throughput mode can vary depending on the Bluetooth module being used, as well as the application and environment in which it is being deployed.
Currently, Shenzhen Muyu Technology Co., Ltd Bluetooth Modules support AT command and Throughput mode. The module MY-BT102 baud rate is 4800bps to 4000000bps. It’s a high-speed Bluetooth dual-mode module.
