In the permanent magnet motor drive equipment for B2B and B2C businesses of APT enterprises, the Bluetooth mode serves as a wireless interaction module that adapts to different communication needs in various scenarios. Although the core functions are all aimed at achieving "device-terminal" data transmission, due to differences in business attributes, they form precise differentiation in application, production, service, and advantages. For example, the B2B Bluetooth module follows industrial standards and uses BLE 5.0 and above versions to ensure transmission stability (resistant to workshop electromagnetic interference), providing pre-support (such as customizing communication protocols to match the enterprise operation platform), mid-term on-site debugging guidance, and post-term remote fault troubleshooting assistance; while the B2C model is designed based on consumer standards, focusing on cost control and compatibility (compatible with iOS/Android systems), and is equipped with online operation guide APP connection tutorials, common problem answers, etc.

The Bluetooth mode was developed by APT Limited for intelligent wireless data transmission. It supports Bluetooth connection with mobile phone APPs, making the debugging operation more convenient. It uses the professional chip and follows the Bluetooth BLE 5.3 specification, featuring both master and slave functions. It supports AT commands, allowing users to change parameters such as serial port baud rate and device name as needed, providing flexible usage. This module supports UART, SPI, and I2C interfaces, and supports 10-port control and ADC acquisition. It has the advantages of low cost, low power consumption, and high sensitivity to reception. With just a few peripheral components, its powerful functions can be realized, and various projects can be customized and developed according to customer requirements.
