Smart
Module Data Sheet
The BGM111 is a Bluetooth
®
Smart module targeted for Bluetooth Smart applications
where good RF performance, low power consumption and easy application development
are key requirements. At +8 dBm TX power BGM111 has best-in-class RF performance
and can provide long range, robust Bluetooth Smart connectivity.
The BGM111 integrates all of the necessary elements required for a Bluetooth Smart
application: Bluetooth radio, software stack and GATT based profiles and it can also
host end user applications, which means no external microcontroller is required in size,
price or power constrained devices. The BGM111 Bluetooth Smart module also has
highly flexible hardware interfaces to connect to different peripherals or sensors.
Although the BGM111 Bluetooth Smart Module is targeted at applications requiring high
RF performance, it still has ultra-low power consumption and can be operated using a
standard 3 V coin cell battery.
BGM111 can be used in a wide variety of applications:
• Health and Fitness
• Point-of-Sales
• Consumer Electronics
• Automotive Aftermarket
• Industrial and Home Automation
• Others

3.2 GPIO Pins
The 25 GPIO pins of BGM111 module are organized into ports with up to 16 pins each. These GPIO pins can individually be configured
as either an output or input. More advanced configurations like open-drain, open-source, and glitch-filtering can be configured for each
individual GPIO pin. GPIO pins can also be overridden by peripheral pin connections like TIMER PWM outputs or USART communica-
tion, which can be routed to several locations on the device. The GPIO supports up to 16 asynchronous external pin interrupts, which
enable interrupts from any pin on the device. Also, the input value of a pin can be routed through the Peripheral Reflex System to other
peripherals. Except for a few special functions, the internal signal crossbar allows various peripheral functions to be assigned freely to
any GPIO pad, simplifying application board layout.
