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.
