Hello,

I want to activate the GPIO 21 from wp8548 via command in airvantage.

In order to do that, I want to use the gpioService, juts like this app does: [https://github.com/legatoproject/legato-af/tree/master/apps/sample/gpioCf3Demo](https://github.com/legatoproject/legato-af/tree/master/apps/sample/gpioCf3Demo)

I’m writing my code based on this app: [https://github.com/nhonchu/Legato16.10-AssetData](https://github.com/nhonchu/Legato16.10-AssetData)

I want to use GPIOService in the AssetData sample.

I tried this:

1. changed assetDataTutorial.adef to:  

2. changed the component.cdef to:  

then I wrote this function in the assetDataMain.c:

static void toggleGPIO()  
{  
bool active;  
active = le\_gpioPin21\_Read();

```
if(active)
{
	LE_INFO("Pin is active, its gonna be deactivated");
	le_gpioPin21_Deactivate();
}

else

{
	LE_INFO("Pin is inactive, its gonna be activated");
	le_gpioPin21_Activate();
}

```

}

I couldn’t run the app, the log gives me:

I don’t know much of communication between apps, I’m sure that’s where I’m getting it wrong.

Can anybody help me?
