The datasheet provides specifications, pin definitions, and AT command details for the BCM9 6 Bluetooth 4.0 module from Blue Invent.
The BCM9 6 is a Bluetooth 4.0 low‑power module that operates from a single 3.3 V supply and supports both master and slave modes. It is built around the CC2541 chip and is intended for applications such as GPS, OBDII diagnostics, printers, cameras, and other Bluetooth data‑transfer products.
Key features include a UART interface, 256 Mbit flash, dimensions of 27 mm × 13 mm × 2.2 mm, and a sleep standby current of less than 5 µA. The module can be configured via a comprehensive AT command set covering baud rate, device name, power mode, and iBeacon broadcasting. This manual is written in Chinese.
