Integrate your Nordic Thingy:91 board.


  • The Thingy:91 board with a USB cable.
  • Installed minicom (for Linux) or RealTerm or PuTTy (for Windows) or other serial communication program.
  • A user with access to the Coiote IoT Device Management platform and appropriate permissions.

Prepare binaries#

Use an already built binary#

To get the latest binaries, navigate to Anjay-zephyr-client releases and download one of the attached .hex files.

In this case we are going to use the demo application, so find the demo_thingy91_app_signed.hex file and go to the flashing part of the tutorial.

Start developement using samples#

Step 1: Get Zephyr and Python dependencies#

To get the Zephyr SDK and dependencies follow the first 4 steps of the instruction provided by the Zephyr Project.

Step 2: Clone the Anjay Zephyr repository#

Enter the command line interface on your machine, then paste and run the following command:

git clone

Step 3: Compile the example#

  1. Connect the Thingy:91 board to a USB port of your machine.
  2. Set West manifest path to Anjay-zephyr-client/demo, manifest file to west-nrf.yml, and do west update:

    west config manifest.path Anjay-zephyr-client/demo
    west config manifest.file west-nrf.yml
    west update
  3. Compile the project for Thingy:91 using west build -b thingy91_nrf9160ns in the demo directory.

  4. Find the app_signed.hex file under the build/zephyr directory in the project folder.

Flash the binaries#

To program the board, go through the whole process of flashing Thingy:91 described here.

After successful flashing, use the nRF Connect Programmer with the .hex file generated or downloaded in a previous step. Then reset the board and go to the next step.

Connect to the LwM2M Server#

To connect to Coiote IoT Device Management LwM2M Server, please register at

To connect the board:

  1. Log in to Coiote DM and from the left side menu, select Device Inventory.
  2. In Device Inventory, click Add device.
  3. Select the Connect your LwM2M device directly via the Management server tile. Add via Mgmt
  4. In the Device credentials step:
    • In the Endpoint name field, enter your board endpoint name e.g. test_device (remember to set the same name in the next section). Device credentials step
    • In the Security mode section, select the Pre-Shared Key mode:
      • In the Key identity field, type test_device
      • In the Key field, type the shared secret used in the device-server authentication.
  5. Click the Add device button and Confirm in the confirmation pop-up.
  6. While in the Connect your device step, follow the next section to run the client and connect.

Configure the Client#

  1. With the board still connected to a serial port interface, open a serial communication program.
  2. Use the anjay command to list possible options:

    uart:~$ anjay
    anjay - Anjay commands
    start   :Save config and start Anjay
    stop    :Stop Anjay
    config  :Configure Anjay params


    To show available subcommands, use the Tab key.

  3. Optionally, change the default credentials by following the instructions in the program.

  4. Use the start command to run the Client.
  5. In Coiote DM, click Go to device to see if your device connected successfully. Registered device
