What I meant is that you should use the light switch server example as a reference and implement the same functionality in the Light_lightness example.

Hi,

What if I am using the original light_lightness example. How do I then send a STATUS message from server to client?

So when I press button 1 and LED1 lights up, server will send a '1' message to client. Similarly, when I press button 2 and LED1 turns off, server will send a '0' message to client.

Like I mentioned in my previuos reply, you can see how this is done in the Light switch server example. You don't have to add all the files, just include the seimple_hal module to handle the buttons. Like Hung mentions in the post I referred to:

"You need to include simple_hal.c to your project just like in the light switch example.
Then you need to call ERROR_CHECK(hal_buttons_init(button_event_handler)); inside intialize() function. "

Hi, thank you for the help.

Now I want to know how to send the STATUS message from server to client. Do I have to add all the files from light switch example into light lightness example? Is there any other posts that can help me with this?

To be more specific: when I press button 1 and LED1 lights up, I want to send a STATUS message to client saying that LED1 is on.

Hi,

I suggest you have a look at the light switch server example. Inside the button_event_handler() you can see how it is done, pressing a button to toggle the LED state and trigger the STATUS message to inform client about the state change You need to include simple_hal.c to your project just like in the light switch example first because the light lightness setup server example does not use the simple_hal module. So you cannot use buttons on the light lightness server by default.

This might also be helpful.

Hi, sorry for the late reply.

So this is the file I'm working on.

In this code, when I press and hold button 1 the LED lits up and stays lit, but I do not want to hold the button for LED to stay lit.

Hi,

Can you provide more details what you are trying to do? What is working and what is not working? What have you tried so far?

[quote user=""]I want to toggle one LED with one button, say when I press button 1, LED 1 will turn on, and when I press button 1 again, LED 1 will turn off. How do I do that? [/quote]

I'm a bit confused by this, do you want to toggle a LED by physically pressing a button or using GPIOTE?
