v 1. INTRODUCTION The BLM211 Bluetooth ® module is a perfect solution for bluetooth low energy single mode application. It can be configured,command and contorlled via simple ASCII string with customer application embeded onto the unit. It is slim and light so the designers can have better flexibilities for the bluetooth low energy product shapes. The BLM211 Bluetooth ® module complies with Bluetooth ® specification version 4.0(single mode). It includes integrated software stack,profiles,and AT modem like commands.It supports maximum bluetooth data rates via UART interface and provides PIO,I2C,SPI interface for external hardware requirement. The detail information of BLM211 Bluetooth® module is presented in this document below.

- PHYSICAL INTERFACE 4.1 Power Supply The transient response of the regulator is important. If the power rails of the module are supplied from an external voltage source, the transient response of any regulator.
4.2 Reset
n The module is reset from several sources: RESET_N pin Power on reset The Reset pin is an active low reset and is internally filtered using the internal low frequency clock oscillator. 4.3 General Purpose Digital IO There are nine general purpose digital IOs defined in the module. It can configure whether peripheral modules control certain pins or whether they are under software control, and if so, whether each pin is configured as an input or output and if a pullup or pulldown resistor in the pad is connected. Each peripheral that connectsto the I/O pins can choose between two different I/O pin locations to ensure flexibility in various applications.
4.4 UART
This is a standard UART interface for communicating with other serial devices. The UART interface provides a simple mechanism for communicating with other serial devices using the RS232 protocol. When the module is connected to another digital device,UART_RX and UART_TX transfer data between the two devices.
4.5 I2C
Any three PIOs can be used as a master I2C interface by configuring the hardware bit serialiser with suitable firmware. The strong pull-ups in the PIO pads eliminate the need for external pull- up resistors. http://www.buddies-tech.com BLM211 DATASHEET
