AT Command Overview • 7. Regulatory and Safety Statements Bluetooth module ZBY-78S | Page of 312 1. Document Description This specification describes the Bluetooth module ZBY-78S. The module is designed for UART transparent transmission applications and is based on the ST17H78S low-power 32-bit controller with BLE 5.0 capability. The module supports BLE 5.0 RF PHY at 1 Mbps and 2 Mbps. It provides low power consumption, compact size, UART communication, configurable RF power, and AT command control for product customization. 1.1 Main Features • Main controller: ST17H78S with SWD support. • Memory: 96 KB ROM and 32 KB SRAM. • Programmable retention in sleep mode and 16 KB OTP support. • Operating voltage range: 1.8 V to 3.6 V. • Integrated LDO and battery monitoring support. • BLE 5.0 operation in the 2.4 GHz ISM band. • Single antenna design without additional RF matching or RX/TX switching. • AES-128 hardware encryption and RSSI reporting. 1.2 Default Application Requirements • Standard firmware baud rate: 115200 bps. • Custom firmware baud rate: 9600 bps or 115200 bps. • The module supports AT+MESHLOG=1 to enable log output. • The module supports AT+MESHNAME=<name> to modify the Bluetooth name. • The MAC address shall be included in advertising packets. • For custom firmware, device information must be obtained after power-on before advertising starts. 2. Mechanical Structure 2.1 Basic Information • PCB size: 10.03 mm x 16.26 mm x 1.0 mm PCBA. • Number of pins: 5 pins. • Antenna: onboard PCB antenna. Figure 1.
