Flash the bootloader

UF2

Serial

• Bootloader download

Step1: Adafruit-nrfutil Installation

Prerequisites

• Python3
• pip3

Installing from PyPI

This is recommended method, to install latest version:

pip3 install --user adafruit-nrfutil

Installing from Source

Use this method if you have issue installing with PyPi or want to modify the tool. First clone this repo and go into its folder.

git clone https://github.com/adafruit/Adafruit_nRF52_nrfutil.git
cd Adafruit_nRF52_nrfutil

Note: following commands use python3, however if you are on Windows, you may need to change it to python since windows installation of python 3.x still uses the name python.exe

To install in user space in your home directory:

pip3 install -r requirements.txt
python3 setup.py install

If you get permission errors when running pip3 install, your pip3 is older or is set to try to install in the system directories. In that case use the --user flag:

pip3 install -r --user requirements.txt
python3 setup.py install

If you want to install in system directories (generally not recommended):

sudo pip3 install -r requirements.txt
sudo python3 setup.py install

To generate a self-contained executable binary of the utility (Windows and MacOS), run these commands:

pip3 install pyinstaller
cd Adafruit_nRF52_nrfutil
pip3 install -r requirements.txt
cd Adafruit_nRF52_nrfutil\nordicsemi
pyinstaller __main__.py --onefile --clean --name adafruit-nrfutil

You will find the .exe in Adafruit_nRF52_nrfutil\nordicsemi\dist\adafruit-nrfutil ( with .exe if you are on windows). Copy or move it elsewhere for your convenience, such as directory in your %PATH%.

Step2: Flash the bootloader

Double click the Reset button on the board and run the following command:

• For Windows:

adafruit-nrfutil --verbose dfu serial --package wio_tracker_1110_bootloader-0.9.1_s140_7.3.0.zip -p COMxx -b 115200

• For others:

adafruit-nrfutil --verbose dfu serial --package wio_tracker_1110_bootloader-0.9.1_s140_7.3.0.zip -p /dev/tty.SLAB_USBtoUART -b 115200

Replace the serial port with your device port. Example:

Download the application

You may use the Meshtastic Web Flasher to download and copy firmware.

Select the device to Seeed Wio WM1110 Tracker and the latest firmware, and download the UF2 file.

UF2

Double click the Reset button, there should be a WM1110_BOOT driver on your PC.
