Pelion Device Management example over 15.4 Thread for Thunderboard Sense 2 board
This example application is not maintained and not recommended. It uses an old version of Mbed OS, Pelion DM, and Arm toolchain. It doesn't work with Mbed Studio.
This example is known to work great on the following platforms:
- Thunderboard Sense 2 - on-chip 802.15.4 Thread 2.4GHz and onboard SPI flash.
Follow the Quick-Start instructions: https://cloud.mbed.com/quick-start
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.
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:
