StopSleep Method
Enter active state, ending the sleep period.
Syntax
mqttsn.stopSleep([callback])
Callback
The 'callback' parameter specifies a function which will be called when the operation completes (or an error is encountered). If the 'callback' parameter is not specified, then the method will block and will not return until the operation completes (or an error is encountered).
The callback for this method is defined as:
function(err){ }
'err' is the error that occurred. If there was no error, then 'err' is 'null'.
'err' has 2 properties which hold detailed information:
err.code err.message
Remarks
Wake up from the sleep state and receive any messages which were buffered by the gateway during the sleep period. This method must be called before the end of the duration specified in the StartSleep method.
Once active, the client is once again subject to KeepAliveInterval supervision just like after connection.
