Getting Started with Seeed XIAO BLE nRF52840 (Sense) | World Smallest Nordic BLE Module

𝗣𝗿𝗼𝗷𝗲𝗰𝘁 𝗗𝗲𝘀𝗰𝗿𝗶𝗽𝘁𝗶𝗼𝗻:
Recently I got 2 boards from Seeedstudio. These two boards are based on Bluetooth Low Energy 5.2 chip called Nrf52840 manufactured by Nordic Semiconductor.

One of the boards is called Seeed XIAO BLE and the other board is Seeed XIAO BLE Sense. There is a difference between these two boards. This 2nd board called Seeed XIAO BLE Sense has IMU Sensor and a PDM Microphone. These small-sized boards are specially designed for IoT and AI applications. This board is an ideal board to run AI using TinyML and TensorFlow Lite.

In this video, we will cover the following topics.

00:00 Introduction
02:14 Learn about the XIAO BLE nRF52840 and XIAO BLE nRF52840 Sense
03:37 Go through the Seeed XIAO BLE Board design, Pins Description & Functions
04:50 Setup Arduino IDE to use nRF52840 Board
06:19 Writing an Arduino Code to Blink an LED
06:54 Learning how to use ADC Pin to control Light Intensity
08:31 Reading Temperature & Humidity Value from DHT11 Sensor
09:36 Displaying text on 0.96″ I2C OLED Display

Looking forward for the next movie showing how to use the 5uA ultra low-power mode with Arduino/Adafruit libraries. I never managed to get it with my Adafruit Bluefruit sense board.

That's still easy. Now try to send the data from the temperature sensor to your cell phone via Bluetooth. I have the same board. Unfortunately I haven't been able to do that with Bluetooth yet. With an Android mobile phone, Arduino Pro Mini and Bluetooth HC-05 there is no problem.

After uploading the blink example, the computer does not see seeduino. Do you have any advice?

Is it possible to use the PDM to record and transmit audio as files or stream over bluetooth? Everything I've seen shows that these devices cannot do both at the same time and that it is impossible to do so because the device simply isn't powerful enough.

I'm interested to know if you use classic bluetooth apart from ble.

Me interesa saber si usa bluetooth clasico aparte del ble.

The 5v pin is an INPUT pin, afaik!! You show it as powering the OLED screen. Did you have another 5v voltage supply powering the breadboard by any chance? Or am I hallucinating?

I'm trying to send the gyroscope data from the Seeed XIAO BLE nRF52840 Sense through bluetooth to my pc, but I have no idea how to connect the sensors wirelessly to the pc and sent data. Anyone who can help me?
