Method Detail

connect

public boolean connect(AccessPoint accessPoint,
                       String password)
                throws TimeoutException,
                       XBeeException

Connects to the provided access point.

This method blocks until the connection with the access point is established or the configured access point timeout expires.

The access point timeout is configured using the setAccessPointTimeout method and can be consulted with getAccessPointTimeout method.

Once the module is connected to the access point, you can issue the writeSettings method to save the connection settings. This way the module will try to connect to the access point every time it is powered on.

Parameters:

accessPoint - The access point to connect to.

password - The password for the access point, null if it does not have any encryption enabled.

Returns:

true if the module connected to the access point successfully, false otherwise.

Throws:

InterfaceNotOpenException - if this device connection is not open.

NullPointerException - if accessPoint == null.

TimeoutException - if there is a timeout sending the connect commands.

XBeeException - if there is any other XBee related exception.

                       XBeeException

Connects to the access point with provided SSID.

This method blocks until the connection with the access point is established or the configured access point timeout expires.

The access point timeout is configured using the setAccessPointTimeout method and can be consulted with getAccessPointTimeout method.

Once the module is connected to the access point, you can issue the AbstractXBeeDevice.writeChanges() method to save the connection settings. This way the module will try to connect to the access point every time it is powered on.

Parameters:

ssid - The SSID of the access point to connect to.

password - The password for the access point, null if it does not have any encryption enabled.

Returns:

true if the module connected to the access point successfully, false otherwise.

The access point timeout is configured using the setAccessPointTimeout method and can be consulted with getAccessPointTimeout method.

Parameters:

ssid - The SSID of the access point to discover.

Returns:

The discovered access point with the given SSID, null if the timeout expires and the access point was not found.
