Pelion example for WIZnet IoT Shield with BG96 Cat.M1, K6xF board (SK telecom network in Korea)

Dependencies:   FXAS21002 FXOS8700Q

Overview

This document is based on https://os.mbed.com/teams/NXP/code/pelion-example-frdm/ and the code forked Daniel_Lee's BG96_K6xF_pelion-example-frdm repository and added some features. Need a WIZnet IoT Shield BG96 board and development board.

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

/media/uploads/hkjung/wiznetiotshield_bg96_frdm-k64f_separate.png /media/uploads/hkjung/wiznetiotshield_bg96_frdm-k64f_stacking.png

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

Requirement

  1. FRDM-K64F or FRDM-K66F
  2. WIZnet IoT Shield BG96 board
  3. USIM card

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.

1. Import the application into your desktop:

mbed import https://os.mbed.com/users/hkjung/code/BG96_K6xF_pelion-example-frdm/
 
cd BG96_K6xF_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 the above command does 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

6. If successfully connect to cellular networks(SK Telecom) then you can get below message
