Please see previous section on how to create an SD card for your RPi.

Copy the application to RPI from the application release folder:

Let's start the application on RPi now.

Test ccsponrust application on Raspberry Pi 3+

The aplication is relying on librbus.so library.

At first start most probably it will fail with:

root@RaspberryPi-Gateway:~# ccsponrust 
ccsponrust: error while loading shared libraries: librbus.so: cannot open shared object file: No such file or directory
root@RaspberryPi-Gateway:~#

Create as symlink to the existing rbus lib.

root@RaspberryPi-Gateway:~# ls -la /usr/lib/librbus.so*
lrwxrwxrwx 1 root root     17 Sep 12 14:47 /usr/lib/librbus.so.0 -> librbus.so.2.0.11
-rwxr-xr-x 1 root root 138548 Sep 12 14:47 /usr/lib/librbus.so.2.0.11
root@RaspberryPi-Gateway:~#

root@RaspberryPi-Gateway:~# 
root@RaspberryPi-Gateway:~# ln -s /usr/lib/librbus.so.2.0.11 /usr/lib/librbus.so       
root@RaspberryPi-Gateway:~#

Start Find or copy ccsponrust on Raspberry Pi.

Subscribe to value changes in data model and Interaction with Web UI

orRunccsponrust with subscribe command on RPI, and change the name of SSID of the Wi-Fi interface on RPi RDK-B Web UI.A notification after applying on the UI will be caught by ccsponrust application.

root@RaspberryPi-Gateway:~# ./ccsponrust --command subscribe --component gl_component --name Device.WiFi.SSIDRadio.12.SSIDChannel --timeout 360036000
Start executing command: subscribe; component: gl_component; name: Device.WiFi.SSIDRadio.12.SSIDChannel

After starting subscribtion enter RDKB Web UI and change related values for 5GHz Wi-Fi AP: SSID or Channel.

A notification after applying on the UI will be caught by ccsponrust application.

Possible issues

Note! Application can change only parameters available for reading and writing for R-Bus from RDKB middleware side.

Some values of data model like like Device.WiFi.SSID.1.SSID doesn’t support set in data model, and it is not possible to set new values for this parameter using rbus. It was tested with default rdkb cli apps.
