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
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:
