Joycon attach/detach function

[jonyluke]

Is there a function for detecting when joycons have been attach or detach?

[yellows8]

There's hidIsControllerConnected (next stable libnx release will have it), but if you want events libnx doesn't have that atm.

EDIT: Or do you mean something else?

[jonyluke]

I want to do an action when joycon is attach and joycon is detach.

[yellows8]

Attached to handheld?

[jonyluke]

Yes

hidGetHandheldMode

[jonyluke]

I don't want to know if it it in Handheld mode, i want to know for example, when attaching the right Joycon, playing a sound, and the same when detaching, is that possible?

I think that is not exactly what I need.

Something like this:

Just use hidGetHandheldMode() or hidIsControllerConnected({handheld})

[jonyluke]

But if you attach or detach the joycon you are not still in HandHeldMode?

[yellows8]

hidGetHandheldMode willl change when you attach/detach a joycon from the handheld when there's a different joycon attached. hidIsControllerConnected({handheld}) will change for {no joycons attached} / {any joycons attached}.

[jonyluke]

With hidIsControllerConnected({handheld}) do you mean hidIsControllerConnected(CONTROLLER_P1_AUTO); ?

CONTROLLER_HANDHELD

[jonyluke]

What do you think of this?

bool mode =  hidIsControllerConnected(CONTROLLER_HANDHELD);
		if(mode){
			//attach
		}
		else{
			//detach
		}

[yellows8]

*connected.

You probably want to compare that with a cached value from the last hidIsControllerConnected call as well.

[jonyluke]

Nothing happens

bool rfirst = true;
bool attach = false;

while (appletMainLoop())
	{
		if(rfirst)
		{
			rfirst = false;
			attach = (hidIsControllerConnected(CONTROLLER_HANDHELD));
		}
		bool nattach = (hidIsControllerConnected(CONTROLLER_HANDHELD));
		if(nattach != attach)
		{
			attach = nattach;
			if(nattach){
				playMp3("attach.mp3");
			}
			else{
				playMp3("dettach.mp3");
			}	
		}
	}

hidScan + other main-loop stuff missing.

[jonyluke]

Okay that is working when the two joycons are connected or not, but how i do it with only one?
Maybe with CONTROLLER_PLAYER_1?

[yellows8]

Don't really support detecting which joycons are connected when there's at least one connected already.

[yellows8]

FWIW, appletMainLoop should not be used when applet is not initialized (didn't realize this was for a sysmodule eariler).

[jonyluke]

I'll have to keep looking for an alternative, because when the joycon connects, a few seconds pass, and does not give the effect I want to give, like detachin the joycon.

[yellows8]

There doesn't seem to be an Event for this with the hid service, dunno for hid:sys (but we don't impl the latter service at all atm).

[jonyluke]

I managed to do it using gpio

[yellows8]

ugh
