Product Description
The SP-BM01 is a Bluetooth module developed based on the YC3020. It uses a Cortex-M0 core processor and integrates Bluetooth 5.0 dual-mode (BR/EDR + BLE). The module features a dual-core architecture, with the M0 core and BT core operating independently without interfering with each other. It offers excellent architecture, high performance, and ultra-low power consumption. The chip includes 512 KB Flash, 64 KB SRAM, and an 8 KB OTP memory area.
The module provides an UART programming interface, allowing configuration settings to be read or written via AT commands through UART.
1. The SP-BM01 is a Bluetooth transparent transmission module. Once the Bluetooth connection is established, it automatically enters transparent transmission mode. When the Bluetooth connection is disconnected, it automatically exits transparent transmission mode.
2. Supports OTA (Over-The-Air) upgrade, allowing the SP-BM01 firmware to be updated via a mobile app.
3. Module configuration can be read or written via AT commands through the UART interface.
4. The UART interface uses hardware flow control to ensure data integrity. Default UART parameters:
Parameter | Value |
Baud Rate | 230,400 bps |
Data Bits | 8 bits |
Parity | None |
Stop Bits | 1 bit |
Flow Control | RTS/CTS |
