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 3V coin cell battery.
