To use the Bluetooth functionality of Seeed Studio XIAO nRF52840, we need to use the official Arduino BLE library. We offer several communication channels to cater to different preferences and needs.
As XIAO form factor, XIAO BLE Sense supports both Grove Shield for XIAO and XIAO Expansion board. This box can store your important stuff, and you are not worried about some people will take your thing, the box has the fingerprint function to protecting your thing, and if the fingerprint authorization failed, the buzzer will alarm and the LED ring will display the red colour, only your finger has registered on the board when the begin, then put your finger on the board, when fingerprint pass the authorization, the LED ring will display green colour.

Same as Seeed XIAO RP2040, it has an onboard 2 MB flash which means it can also be programmed by Arduino, MicroPython, CircuitPython, or other program languages.
Check the connection (making sure the device is not in bootloader mode) or choose "Configure interpreter" in the interpreter menu (bottom-right corner of the window) to select specific port or another interpreter. Go to the Seeed Studio XIAO nRF52840 Bluetooth interface and click on the device to display the device details. when you plug the battery please watch out for the positive and negative anodes, follow the picture to connect the battery in case of damage the board. Seeed Studio XIAO nRF52840 is carrying wireless capability for the first time and it supports B luetooth 5.0, also able to operate with low power consumption. The first test was great - I'll have to test the other functions at the next opportunity.
It features an onboard antenna, 6 Dof IMU, microphone, all of which make it an ideal board to run AI using TinyML and TensorFlow Lite.
If you have any questions about what we offer then drop us a line. "PM2.5 concentration(Atmospheric environment,unit:ug/m3): ". E3F-5DN3/5L / G18-3C5NC
It supports UART, IIC, and SPI all three common serial ports.
This simple and inexpensive project is based on the Seeed Studio Expansion Base for XIAO to report the heart rate.
That's the pin you used to blink the orange LED!

Passive buzzer: You could change the PMW frequency to award different beep sound to get a "buzzer music". The powerful performance makes it perfect for TinyML AIoT projects requiring gesture/voice recognition, and the tiny size allows it to be used in wearable devices and Internet of Things projects, not just for prototypes but the mass production.
As the advanced version of the board XIAO BLE, Seeed XIAO BLE Sense has equipped a powerful Nordic nRF52840 MCU which is designed in a Bluetooth 5.0 module, built around 32-bit ARM Cortex-M4 CPU with Floating-Point Unit(FPU) operating at 64Mhz.
Featuring onboard IMU and PDM. Install the Arduino-IRremote and Motor driver library, this is the guide how to install the library.
