ST / Mbed OS mbed-os-example-client-Sensors_6LowPan

Mbed OS Device Connector client pushing environmental sensor data via 6LowPan.

Dependencies:   X_NUCLEO_IKS01A2

Fork of mbed-os-example-client-Sensors_6LowPan by Nicola Capovilla

The application is derived from the official mbedOS client example (link) and has been tested using a X-NUCLEO-IDS01A4 SubGHz 6LowPan connectivity board and a X-NUCLEO-IKS01A2 (default) or a X-NUCLEO-IKS01A1 motion and environmental sensors expansion board connected to a ST NUCLEO-F429ZI platform.
The following steps should be performed to make the application work:

  • Register and login into ARM mbed Connector.
  • Replace the default and empty security.h file with the one associated with your account and provided by the Connector (Security Credentials menu).
  • In order to use X-NUCLEO-IKS01A1 instead of default X-NUCLEO-IKS01A2 comment out the IKS01A2 macro definition in main.cpp file.
  • Choose NUCLEO-F429ZI as a target either from online compiler or from CLI, compile and flash.
  • Setup and connect a NUCLEO-F429ZI + X-NUCLEO-IDS01A4 6LowPan border router as explained here
  • Open a serial terminal (params 115200N1) and wait that the client is connected to the mbed Connector via the border router.
  • As soon as the client is connected it will start acquiring and pushing the environmental (pressure, temperature and humidity) data to the cloud.

Note: environmental data are expressed using IPSO representation based on OMA LWM2M standard.

 *  NOTE! This is an optimized, minimal configuration for mbed Client.
 *  We know it works with mbed Client but if you want to add more
 *  services/communications to the application yourself - please ensure
 *  you update this configuration accordingly. The default configuration
