Thunderboard Sense 2

Example functionality

This example showcases the following device functionality:

  • Read onboard sensors, and report them as Pelion LWM2M resources:
    • Barometric Pressure and Temperature (BMP280)
    • Relative Humidity and Temperature (Si7021)
    • Air quality - CO2 and tVOC (CCS811)
    • Light intensity and UV level (Si1133)
    • Hall effect and Temperature (Si7210)
    • Accelerometer and Gyroscope (ICM20648)
  • It also exposes the RGB LEDs for triggering flashes in a specific color
  • On user button click, increment Pelion LWM2M button resource.

15.4 Thread setup

This example program requires that a Thread Border Router is available. A Border Router is a network gateway between a wireless 6LoWPAN mesh network and a backhaul network. It controls and relays traffic between the two networks. In a typical setup, a 6LoWPAN border router is connected to another router in the backhaul network (over Ethernet or a serial line) which in turn forwards traffic to/from the internet or a private company LAN, for instance.

Instructions how to set up a Thread Border Router

Use this example with Mbed CLI

1. Import the application into your desktop:

mbed import https://os.mbed.com/teams/SiliconLabs/code/pelion-example-tbsense2

cd pelion-example-tbsense2

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 TB_SENSE_2

(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:
