Emartee CuteDigi BMX Bluetooth to UART/I2C/USB Module (GEN II) CuteDigi BMX Bluetooth to UART module uses CSR BlueCore4- External chipsets. It embeds 8Mbit flash for software storage, and supports 3.3V power supply. BMX is a muti-function module. It can be used in different products according to the embedded firmware settings. It is especially targeted for data transfer. The second generation Bluetooth UART module has two working mode: AT command mode, and automatic binding transparent data mode. In automatic binding data transparent mode, it can be configured to Master, Slave or Loopback three different modes, and it will connect to or be connected by other devices that support SPP protocol per configuration. In AT command mode, user can configure the module and send control commands. By controlling logical level of IO pin PIO11, user can switch the working modes between AT command mode and transparent data mode.

PIO8 is used to control LED indicating the status. It will blink after power on. Different blink intervals are used to indicate different status. 2. PIO9 is used to control LED indicating paring. It will be steady on when paring is successful. 3. PIO11 is used to switch the working mode. High level-> AT command mode Floating or low level-> normal transparent data mode. 4. The module has built-in power on reset circuitry. 2 / 23
