Hardware
The API provides a function called
ON()
in order to switch the XBee module on. This function supports a parameter
which permits to select the SOCKET. It is possible to choose between SOCKET0 and SOCKET1.
Selecting SOCKET0 (both are valid):
xbee868LP.ON();
xbee868LP.ON(SOCKET0);
Selecting SOCKET1:
xbee868LP.ON(SOCKET1);
In the case two XBee 868LP modules are needed (each one in each socket), it will be necessary to create a new
object from WaspXBee868LP class. By default, there is already an object called xbee868LP normally used for
regular SOCKET0.
In order to create a new object it is necessary to put the following declaration in your Waspmote code:
WaspXBee868LP xbee868LP_2 = WaspXBee868LP();
Finally, it is necessary to initialize both modules. For example, xbee868LP is initialized in SOCKET0 and xbee868LP_2
in SOCKET1 as follows:
xbee868LP.ON(SOCKET0);
xbee868LP_2.ON(SOCKET1);
The rest of functions are used the same way as they are used with older API versions. In order to understand them
we recommend to read this guide.
Warnings:
•
Avoid to use DIGITAL7 pin when working with Expansion Board. This pin is used for setting the XBee into sleep.
•
Avoid to use DIGITAL6 pin when working with Expansion Board. This pin is used as power supply for the
Expansion Board.
•
