  1. download the most recent MicroPython firmware .bin file to load onto your ESP32 device. You can download it from the MicroPython downloads page

For best results it is recommended to first erase the entire flash of your device before putting on new MicroPython firmware.

Currently we only support esptool.py to copy across the firmware. You can find this tool here: https://github.com/espressif/esptool/, or install it using pip:

pip install esptool

Using esptool.py you can erase the flash with the command:

esptool.py --port /dev/ttyUSB0 erase_flash

deploy the new firmware using:

esptool.py --chip esp32 --port /dev/ttyUSB0 write_flash -z 0x1000 esp32-20180511-v1.9.4.bin

Arduino Set up

https://wiki.seeedstudio.com/XIAO_BLE/

Step 3. Add Seeed Studio XIAO nRF52840 (Sense) board package to your Arduino IDE

Navigate to File > Preferences, and fill “Additional Boards Manager URLs” with the url below: https://files.seeedstudio.com/arduino/package_seeeduino_boards_index.json

Attention:All the I/O pins are 3.3V, please do not input more than 3.3V, otherwise, the CPU may be damaged.

The red one is positive (+), the black one is negative (-). Never connect the red cable to the negative battery terminal or a vehicle with a dead battery.

Setting Up Arduino IDE

https://how2electronics.com/getting-started-with-seeed-xiao-ble-nrf52840-sense/

  1. Connect the XIAO BLE (Sense) to your computer via a USB Type-C cable.

  2. Download and Install the latest version of Arduino IDE according to your operating system. Then launch the Arduino application.

  3. There is no pre-installed package for NRF52840 Board. So we need to first install the board on Arduino IDE. To do that Navigate to File > Preferences, and fill “Additional Boards Manager URLs” with the URL below: https://files.seeedstudio.com/arduino/package_seeeduino_boards_index.json

  4. Navigate to Tools > Board > Boards Manager, type the keyword “seeed nrf52” in the search box, select the latest version of Seeed nRF52 Boards, and install it.
