Key Features
• If the mobile phone APP and the Bluetooth slave need to transmit large packets of data, the mobile phone Bluetooth must support BLE4.2 or above.

• Support for Bluetooth slave roles and Bluetooth host roles based on the BLE 4.2 protocol

• Bluetooth slave version supports OAD upgrade

• Bluetooth host version supports SBL upgrade

• The slave version supports both single-link and multi-link versions.

• Serial packet length, single link version supports up to 248Byte, multi-link version supports up to 20Byte

• High-speed two-way transparent transmission, the fastest two-way up to 12KByte/s (single link big packet transmission)

• Single link version default 20ms connection interval, fast connection

• User interface uses universal serial port design, full duplex bidirectional communication, baud rate range 9600bps ~ 256000bps (default)

• Supports bridge mode (serial port pass-through) or direct drive mode (no additional CPU required); direct drive mode supports SPI/UART interface

• Support SPI/UART instruction software reset module to get MAC address

• Support SPI/UART commands to adjust Bluetooth connection interval and control different forwarding rates

• Support SPI/UART command to adjust transmit power, modify broadcast interval/connection timeout time, modify serial baud rate, modify module name, all will be saved after power down

• Support mobile device APP/SPI/UART Modify module name, save power, save serial port baud rate, product identification code, custom broadcast content, broadcast cycle, save power

• APP/SPI/UART can operate all IO external expansion

• Support connection status, broadcast status prompt pin / normal IO flexible configuration

• Up to 24 bidirectional programmable IOs with external interrupts for input detection and full low power operation. (lighting control, remote control toys, and other input and output switch applications)

• Very low power standby mode

• Support APP/UART/SPI setting TX power/RX gain, adjust different transmission sensitivity for application distance adjustment

• Supports APP/UART/SPI free on/off broadcast for true deep sleep
