Bluetooth® Low Energy
Industry’s Easiest-to-Use Bluetooth Low Energy Solution
Our approach to Bluetooth Low Energy (BLE) is simple: remove as many barriers as possible to allow you to focus on your design. Our BLE solutions are designed to be easy to use right out of the box. Because they are certified to the Bluetooth 5.0 standard, you don’t need to spend valuable time and money on Bluetooth certification testing. When you select one of our products, you also get a complete set of resources to help you go quickly from concept to prototype, including:
- Thorough documentation
- Application examples
- Turnkey reference designs
- Free mobile app source code
- Microchip’s complimentary Wireless Design Check service
Bluetooth Network Processors
Our preprogrammed Bluetooth Network Processor solutions remove the complexity of managing Bluetooth from your application, reducing your risk and time to market. They offer simple interfaces and support PIC®, SAM and third-party microcontrollers (MCUs) for maximum design flexibility while requiring minimal host resources.
- Easy to use with minimal support required
- Application runs on host MCU
- Offloads Bluetooth stack processing for design flexibility
- Simple ASCII or binary interface over UART
- Enhanced security and throughput
With our Bluetooth Low Energy modules, there’s no need to be an RF expert or navigate the costly and time-consuming certification process. These modules come with global certification, preprogrammed firmware and a simple ASCII interface for ease of use. Each module’s data sheet also provides board placement and layout guides to further simplify your development.
- Fully certified for use in USA, Canada, Europe, Japan, China, Korea and Taiwan to save time and money
- ASCII interface enables simple communication with host MCU
- Preprogrammed with user-friendly firmware
- Drop-in wireless cable replacement
- High level of integration significantly reduces external Bill of Material and costs
One of the best things about BLE is how easy it is to connect to a smartphone, eliminating the need for a separate LCD. Not surprisingly, the Smartphone App has become an essential building block for BLE applications that are based on our modules.
We make it easy for you to develop your own Smartphone App by providing mobile apps and free source code to speed up development. The Microchip Bluetooth Data (MBD) App is available for both iOS® and Android™ operating systems.

Ready to Get Started?
Order your development board. We recommend the BM71 Xplained Pro Development Board (DM164146). Featuring a BM71 Bluetooth Low Energy Module, this all-inclusive starter kit has everything you need to get up and running in a few minutes. Once you have purchased your board, follow the remainder of these steps to get started with your project
Ensure that the BM71 Xplained Pro Development Board is configured as follows:
- The jumper on the J2 header is closed to select USB power option
- The current measurement jumper on J3 is present
- Switch 1 (system configuration) on the DIP switch is set to OFF
- Switch 2 (Blue LED) on the DIP switch is set to ON
Connect the BM71 Xplained Pro Development Board to a host PC using the mini USB cable. Ensure that green LED (LD1) is solid ON indicating USB power.
Start the Terminal Emulator software.
Open the mBIoT app on the phone/tablet and ensure that Bluetooth is turned ON.
On the MBD App Dashboard screen, select "BM70"
In the follow-up screen, click on “Scan” and “Scan” again at the bottom.
Once the scanning process completes, the BM71 module should appear as “BM71_BLE” by default.
Click on the “BM71_BLE” to start a connection process. Once connected, the transparent UART service available on the BM71 module should show up.
Click on “Transfer data to device”. The Transparent UART screen should open. The data pipe is now open.
In the serial emulator application (TeraTerm), enter any text and this should show up in the transparent UART page in the app.
Featured Development Tools
The BM71 Xplained Pro Development Board is a hardware platform designed to evaluate and test the capabilities of the BM71 Bluetooth® RF module.
