The Ring Indicator pin is used to allow the module to wake up a host device.

IPC interfaces binding

All the functions of this API are provided by the modemService app.

Here's a code sample binding to modem services:

bindings:
{
   clientExe.clientComponent.le_riPin -> modemService.le_riPin
}

Ring Indication signal

The RING pin can be configured to notify a host device with different timing of pulse signals for different module activities.

le_riPin_AmIOwnerOfRingSignal() function checks whether the application core is the current owner of the Ring Indicator signal.
le_riPin_TakeRingSignal() function takes control of the Ring Indicator signal.
le_riPin_ReleaseRingSignal() function releases control of the Ring Indicator signal.

Warning: Your platform may require a reboot to take into account this change. Please refer to your platform documentation for further details.

le_riPin_PulseRingSignal() function sets the ring signal high for configurable duration of time before lowering it.
