DiscoverGateway Method

Broadcast a SEARCHGW message to network clients and gateways.

Syntax

mqttsn.discoverGateway(broadcastRadius, [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

Broadcast a SEARCHGW message in order to discover nearby gateways. Network clients and gateways may respond with a GWINFO message containing a gateway id. Such a response will trigger the GatewayInfo event.

This functionality is not yet implemented.
