Generic Pelion Device Management example for various Advantech modules.
This example is known to work great on the following platforms:
- WISE-1530 WiFi Module using DB-1505 carrier board and external SD card reader.
Example Functionality
This example showcases the following device functionality:
- On timer button increment, simulate Pelion LWM2M button resource change
Use this example with Mbed CLI
1. Import the application into your desktop:
mbed import https://os.mbed.com/teams/Advantech/code/pelion-example-common cd pelion-example-common
2. Download your developer certificate from pelion portal
3. Compile the program
mbed compile -t <toolchain> -m <TARGET_BOARD>
(supported toolchains : GCC_ARM / ARM / IAR)
4. Copy the binary file pelion-example-common.bin to your mbed device.
