Features

AI Translation
  • Easy to use — no Bluetooth protocol stack experience required
  • Supports Bluetooth master, Bluetooth slave, and Bluetooth master-slave combo — 3 versions available
  • Universal UART user interface, full-duplex bidirectional communication, minimum baud rate 9600bps
  • Supports both bridge mode (serial transparent transmission) and direct-drive mode (no additional CPU required); direct-drive mode supports UART/IIC/SPI interfaces
  • Default 20ms connection interval for fast connection
  • UART/IIC/SPI command support for software module reset and MAC address retrieval
  • UART/IIC/SPI command support for Bluetooth connection interval adjustment, controlling different forwarding rates (dynamic power consumption adjustment)
  • UART/IIC/SPI command support for TX power adjustment, advertising interval/connection timeout/connection latency count modification, baud rate modification, and module name modification — all saved on power-off
  • Serial data packet length: any length up to 128 bytes (inclusive), with automatic segmentation for large packets
  • High-speed bidirectional transparent forwarding, up to 1K/S
  • Mobile APP/IIC/SPI/UART support for module name modification (saved on power-off), baud rate modification, product ID, custom advertising content, and advertising interval — all saved on power-off
  • Mobile APP/IIC/SPI/UART support for remote module reset and TX power configuration
  • Mobile APP/IIC/SPI/UART support for Bluetooth connection interval adjustment, saved on power-off (dynamic power consumption adjustment)
  • APP/IIC/SPI/UART full access to all extended IOs
  • 6 bidirectional programmable IOs with external interrupt-triggered input detection, full low-power operation (lighting control, remote-controlled toys, and various digital input/output switch applications)
  • 2 programmable single-shot/cyclic toggle output ports
  • 8-channel ADC input (12-bit), enable/disable and sampling period freely configurable, with optional averaging filter (temperature/humidity sensing, light intensity measurement, and similar applications)
  • 6-channel programmable PWM (1 MHz) output (dimming, speed control, and similar applications)
  • Continuous RSSI acquisition on module side, readable or auto-notify to APP, enable/disable and acquisition frequency freely configurable (item tracking and loss-prevention alarm applications)
  • Battery level indication and reading support, with auto-reporting capability (device battery reminder)
  • Internal RTC support, synchronizable and calibratable from APP at any time
  • IO configuration and output state saving, with customizable default initialization states
  • Shallow restore and deep restore modes for flexible user data recovery while retaining essential product configurations
  • Bluetooth connection status strings (connected, normal disconnect, and timeout disconnect) retrievable via TX UART
  • Low-level enable mode and pulse-width enable mode support, remote shutdown support, ultra-low-power standby mode
  • Master scanning support for up to 8 MAC addresses, scanned MAC address readback, total slave count retrieval, and arbitrary slave connection/disconnection
  • Command/data communication free switching; 200-byte user storage area (25 pages, 8 bytes per page), saved on power-off
  • Free switching between Bluetooth master and slave roles
  • APP/IIC/UART/SPI free switching of TX power/RX gain for adjustable transmission sensitivity to achieve variable communication range
  • APP/IIC/UART/SPI free enable/disable of advertising for true deep sleep; full IO read/level output support; APP/IIC/UART/SPI command support for clearing data buffer and rejecting incoming data
  • Power-on slave mode support (saved on power-off); power-on watchdog support to prevent Bluetooth firmware lockup
  • APP/IIC/UART/SPI password configuration support
