Mbed OS and Pelion Device Management example for FRDM-K64F and FRDM-K66F boards

Dependencies:   FXAS21002 FXOS8700Q

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

  • FRDM-K64F - onboard Ethernet and onboard SD card holder.
  • FRDM-K66F - onboard Ethernet and onboard SD card holder.

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

FRDM-K64F FRDM-K66F

Example functionality

This example showcases the following device functionality:

  • Read onboard FXOS8700Q accelerometer and magnetometer, and report the values as Pelion LWM2M resources (see image below).
  • (FRDM-K66F only) Read onboard FXAS21002 gyroscope and report the values as Pelion LWM2M resources.
  • 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.

Use this example with Mbed CLI

1. Import the application into your desktop:

mbed import https://os.mbed.com/teams/NXP/code/pelion-example-frdm

cd pelion-example-frdm

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 1.9.x or above.

4. Compile and program:

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

(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:
