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

RHOMBIO_L476DMW1K over WiFI and using onboard QSPI flash.

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

Example functionality¶

This example showcases the following device functionality:

• Read onboard MCU ADC temperature and MCU ADC voltage reference, and report them as Pelion LWM2M resources (see image below).
• On user button click, increment Pelion LWM2M button resource.
• Allow the user to change the state of the board LED from Pelion LWM2M led_state resource and PUT request.
• External sensors can be easily added to the kit and then sensor readings reported as Pelion LWM2M resources.

Use this example with Mbed CLI¶

<<1. Import the application into your desktop:>>

mbed import https://os.mbed.com/teams/rhombio/code/pelion-example-rhombio-l476dmw1k

cd pelion-example-rhombio-l476dmw1k <</code>>

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 DISCO_L475VG_IOT01A

(supported toolchains : GCC_ARM / ARM / IAR)

5. You can connect on a virtual terminal/COM port to the platform using:

mbed sterm -b 115200

This should give you an output similar to:
