(Low power BLE4.0 Bluetooth module)

BLE4.2 Protocol Bluetooth module

BL12 is a bluetooth serial port transparent transmission module to achieve transparent transmission between Bluetooth interface data and serial port (UART) data. It is compatible with BLE4.2 standard protocol and supports single mode BLE. Identify the virtual serial port device on the PC or mobile device after bluetooth connection. Provides communication Settings in slave mode, including bluetooth information, vehicle information and other parameters. Serial port, with the highest baud rate of 1Mbps, provides AT instruction configuration and supports MODEM contact signals.
