1. Launch the following command in order to download the project:

  mbed import https://os.mbed.com/teams/Avnet-Silica/code/mbed-os-sensor-node/
  cd mbed-os-sensor-node/

. The command "mbed deploy" will require few minutes.

2. From the root of the project open *mbed_app.json* file and modify the following line:

• change "spirit1.mac-address": "{0x7, 0x6, 0x5, 0x4, 0x3, MONTH, DAY, YEAR}" substituting MONTH, DAY, YEAR with hex numbers. For example your birth date.

3. Go to https:connector.mbed.com webpage and login into it.

4. Go to the page https:connector.mbed.com/#credentials and click on Get my device security credentials:

5. Copy the text showed on grey background.

6. In the root directory of the project open *security.h* file and paste substituting all text.

7. Compile the project for the sensor node:

<<code>> mbed compile -t GCC_ARM -m SILICA_SENSOR_NODE -c <</code>

where:

• -t selects the toolchain used.

• -m selects the device compiled for.

• -c rebuilds all from scratch.

8. At the end of the compilation you will have a screen like this:

9. The firmware has been created at *BUILD
SILICA_SENSOR_NODE
GCC_ARM
mbed-os-sensor-node.bin*

10. Copy the binary file into the mass-storage of the board. Once it is copied the demo will start.
