B-L462E-CELL1/TYPE1SC#

Integrate your B-L462E-CELL1 Discovery kit board along with the TYPE 1SE module with built-in eSIM (ST4SIM-200M).

Prerequisites#

  • The B-L462E-CELL1/TYPE1SC board with a USB cable.
  • Installed STM32CubeIDE.
  • 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.

Prepare binaries#

Use an already built binary#

To get the latest binary file and flash the board:

  1. Go to Anjay-freertos-client.
  2. Download the Anjay-freertos-client-B-L462E-CELL1-TYPE1SC.bin file.
  3. To flash the board, open your File manager and drag the downloaded .bin file to your DIS_L462RE external device.
  4. You will see a blinking diode on your board. The diode will stop blinking as soon as the flashing is finished.

The board is now flashed: you can go to the Connecting to the LwM2M Server step.

Start development using samples#

Note

This step is optional. If you've gone through the Use an already built binary step, you can go to Connecting to the LwM2M Server right away.

Step 1: Cloning the Anjay freeRTOS client repository#

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

git clone --recursive https://github.com/AVSystem/Anjay-freertos-client

Step 2: Compiling the board#

  1. Connect the B-L462E-CELL1/TYPE1SC board to a USB port of your machine.
  2. Go to the STM32CubeIDE.
  3. Import the project cloned in the previous step to your workspace:
    • From the navigation bar, select File and click Import.
    • From the General list, select Existing Projects into Workspace and click Next.
    • In Select root directory, indicate the catalog containing the cloned Anjay freeRTOS client repository.
    • In the Projects field, select Anjay-freertos-client-B-L462E-CELL1-TYPE1SC and click Finish. Import project
  4. In the Project Explorer, navigate to the Anjay-freertos-client-B-L462E-CELL1-TYPE1SC project:
    • Right-click on the project name and select Build Project. The build should take less than one minute to complete.
    • After the build is finished, right-click on the project name, select Run As and click the 1 STM32 Cortex-M C/C++ Application option.
      • In the Lauch Configuration Selection, choose the Anjay-freertos-client-B-L462E-CELL1-TYPE1SC option and click OK.
  5. After the build and run are complete, the board is now compiled.

Connecting to the LwM2M Server#

To connect to Coiote IoT Device Management LwM2M Server, please register at https://eu.iot.avsystem.cloud.

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
    1. In the Device credentials step:
      • In the Device ID enter your board endpoint name, e.g. test_device. Device credentials step
      • In the Security mode section, select the PSK (Pre-Shared Key) mode:
        • In the Key identity field, type the same name as in the Endpoint name field.
        • In the Key field, type the shared secret used in the device-server authentication.
    2. Click the Add device button and Confirm in the confirmation pop-up.
    3. In the Connect your device step, follow the next section to run the client and connect it to the server.

Configuring the Client#

  1. With the board still connected to a serial port interface, open a serial communication program.

  2. Press the reset button located on the board. This should trigger the following prompt:

    Press any key in 3 seconds to enter config menu...

  3. Press any key and in the configuration menu, change the default credentials to your data by following the instructions presented in the program and save it. Client configuration

    Important

    APN (Access Point Name) is the name of a gateway between a GSM, GPRS, 3G and 4G mobile network and another computer network. If you use built-in eSIM card truphone then change APN to iot.truphone.com.

    Note

    If you use external eSIM card you have to check APN used by SIM card's provider.

  4. Go to Coiote DM to check if your device connected. Click Next, then Go to Summary, then Finish. You will see your Device Center view:

Registered device

Tip

LwM2M Server URI, endpoint name and other information can be found in the Configuration tab.
