K6xF board with BG96 of WIZnet for CatM1 board.

Dependencies:   FXAS21002 FXOS8700Q

This document is based on https://os.mbed.com/teams/NXP/code/pelion-example-frdm/

This code could be access via Cat.M1(BG96 module) of SK telecom network in Korea. Need a WIZnet BG96 board or can connect directly to M2Mnet BG96 module and development board.

board board

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

  • BG96 RESET = D7
  • BG96 PWRKEY = D9
  • BG96 TX = D1
  • BG96 RX = D0
  • BG96 VCC = VCC(5V)
  • BG96 GND = GND

Requirement

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 http://os.mbed.com/users/Daniel_Lee/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. If successfully connect to cellular networks(SKTelecom) then you can get below message
