Example
This example will wait for RF coverage to resume and sound a tone when it is
available. While waiting, a “tic” sound will be made periodically to indicate the
check. This sample is more complex than needed, but it illustrates how to use
global variables and timers to periodically check state.
/* RFSoundOnConnect */
// Global control variables
var RFWakeupSoundTimerID = 0;
var RFWakeupSoundContinue = 0;
var RFWakeupSoundInterval = 200; // milliseconds
var RFWakeupSoundCountMaximum = 50; // 50*200 = 10 seconds
var RFWakeupSoundCount = 0;
function OnWakeup ()
{
// Start with wakeup event
RFWakeupSoundStart();
}
// Function to start RF check
function RFWakeupSoundStart()
{
if (!RFWakeupSoundContinue)
{
RFWakeupSoundContinue = 1;
if (RFWakeupSoundTimerID != 0)
{
// Stop and clear any previous check
CETerm.ClearTimeout( RFWakeupSoundTimerID );
RFWakeupSoundTimerID = 0;
}
RFWakeupSoundCount = 0;
// Schedule first RF check
RFWakeupSoundTimerID = CETerm.SetTimeout(
"RFWakeupSoundOnTimer();",
RFWakeupSoundInterval );
}
}
// Function to check RF and notify user
function RFWakeupSoundOnTimer()
{
RFWakeupSoundTimerID = 0;
RFWakeupSoundCount++;
// Get and check info
var rfStatus = CETerm.GetProperty( "device.rf.status" );
