REYAX RYWB116 Embedded BLE Software Programming Reference Manual

About this manual

The document serves as a technical guide for developers to write software on a Host MCU that controls and operates the REYAX RYWB116 module. It describes the Bluetooth Low Energy (BLE) commands, including parameters, valid values, and expected responses from the modules.

Key topics covered include the embedded BLE architecture, bootloader operations, various hardware interfaces (UART, USB-CDC, SPI), command modes (AT and Binary), GATT profile management, security protocols, power save modes, and a comprehensive API library with function prototypes.
