Try to implement LED Blinky on Matter Template Example code.

Varshil

I want to modify the example code which is provided by Matter SDK and there are several examples are there are Light bulb example code, Light Switch example code and Template code as well. Now I just right now simply wants to understand the code and modify it.


But it very complex to understand the code so can you please provide or explain the basic flow of Template like how it works. 

And also, I want to modify that code want to do some practical's like blink an LED but i did not know exactly where in that code I have to Change.

Please your help will be appreciated.

    Hi,

    I will assist you with that issue in your other ticket so we can keep this ticket focused on the Matter temperature sensor.

    Best regards,

    Hey  ,

    As you guide me in above all steps like to read Thingy Example code and then follow the steps of (Adding clusters to Matter application — nRF Connect SDK 2.4.0 documentation (nordicsemi.com).

    I followed all the steps as you told me but I got stuck at one place.

    Now when I pass the command to the Chip-Tool and below I pasted the commands which I write in Chip-Tool.

    sudo ./chip-tool-debug onoff off 12 1

    sudo ./chip-tool-debug identify identify 10 12 1

    And After this commands I got an Error that:

    I: 34957 [SC]Received Sigma3 msg

    So can you little bit guide me for solving this and also I want to know that what is next step for printing Temperature value from DHT11 Sensor.

    Hi,

    I have been out of the office. Have you been able to fix the issue and get the temperature value from the sensor?

    Best regards,
    Marte
