Nuvoton / Mbed OS pelion-example-common

Generic Pelion Device Management example for various Nuvoton-based boards.

DEPRECATED

This example application is not maintained and not recommended. It uses an old version of Mbed OS, Pelion DM, and Arm toolchain. It doesn't work with Mbed Studio.

Please use: https://os.mbed.com/teams/mbed-os-examples/code/mbed-os-example-pelion/

This example is known to work great on the following platforms:

Follow the Quick-Start instructions: https://cloud.mbed.com/quick-start

Example functionality

This example showcases the following device functionality:

  • On timer button increment, simulate Pelion LWM2M button resource change

Use this example with Mbed CLI


1. Import the application into your desktop:

mbed import https://os.mbed.com/teams/Nuvoton/code/pelion-example-common
cd pelion-example-common


2. Install the CLOUD_SDK_API_KEY

mbed config -G CLOUD_SDK_API_KEY <PELION_DM_API_KEY>

For instructions on how to generate your API key, please see the documentation.

3. Initialize firmware credentials (done once per repository). You can use the following command:

mbed dm init -d "<your company name in Pelion DM>" --model-name "<product model identifier>" -q --force

If above command do not work for your Mbed CLI, please consider upgrading Mbed CLI to version 1.8.x or above.

4. Compile and program:

mbed compile -t <toolchain> -m <TARGET_BOARD>

(supported toolchains : GCC_ARM / ARM / IAR)

5. Copy the binary file pelion-example-common.bin to your mbed device.

Note

This platform and application is suitable for evaluation and initial development. For production purposes, we recommend to use a different variant with built-in security features
