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 binaries, navigate to Anjay-freertos-client.

In this case we are going to use the Anjay-freertos-client-B-L462E-CELL1-TYPE1SC.bin file which after being downloaded must be added to B-L462E-CELL1/TYPE1SC board folder.

Start developement using samples#

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.

  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.
