Bluetooth LE Benefits and Limitations
Bluetooth is one of the most common wireless protocols used to connect electronic devices. It is present in devices all around us—video game controllers, smartphones, keyboards, mice, audio speakers and more. To determine if Bluetooth is right for your application, consider the following features and limitations:
- Every modern smartphone supports Bluetooth LE. If your application needs to connect to a phone, Bluetooth is the way to go. Example applications include smart home devices, garage door openers and smart sensors.
- Although most applications require a shorter range, Bluetooth LE can maintain connections up to around 200 meters. This makes it perfect for smart home devices.
- As the name suggests, Bluetooth LE is perfect for applications where low power consumption is important, such as battery-operated devices.
- Our Bluetooth devices support multi-link capability, which means they can maintain connections with up to six devices simultaneously. For a larger network of devices, consider the Zigbee protocol.
- Bluetooth is a mature and well-defined specification, which makes it relatively easy to implement. Building a Bluetooth application from scratch is easy with our building blocks, even if you have no experience with wireless development. We also offer a plug-and-play module that eliminates the need for software development.
Bluetooth's combination of smartphone connectivity, range, power consumption and ease of development make it a popular choice for application designers.

RNBD451 Add-on Board
Our out-of-the-box demo application will have you prototyping with the RNBD451PE module in minutes. This board is mikroBUS™ socket and PC compatible.
RN4871 click
The RN4871 click uses an ASCII command interface over UART to communicate with a host MCU. Additional functionality can be provided by the RST, CS and INT pins on the mikroBUS socket.
RN4870 click
The RN4870 click uses an ASCII command interface over UART for communication with a host MCU. Additional functionality can be provided by the PWM, INT, RST and CS pins on the mikroBUS socket.
RN4678 click
The RN4678 click uses an ASCII command interface over UART for communication with a host MCU. Additional functionality can be provided by the N, RST, CS, PWM and INT pins on the mikroBUS socket.
Mobile Apps
Most Bluetooth applications rely on a smartphone for interface functionality, so mobile apps have become an essential building block in these solutions. To reduce your application development time, we provide the Microchip Bluetooth Data (MBD) application and source code for free. Use them as they are for rapid prototyping or build your own using our source code as a starting point.
