Note: In “Waspmote data frame guide” document is located more extensive information about how to build the frame.
To delete sensor the user must press the garbage can that appears to the left of the description of the sensor. To complete the

27.2.6. Sending XBee frames from Meshlium to Waspmote
Meshlium can also send XBee frames to the Waspmote nodes. In order to use this feature you have to stop the “capturing and
storing” daemon which is running in the system.
To do so access by SSH to Meshlium and stop the default ZigBee daemon::
$ /etc/init.d/ZigbeeScanD.sh stop
Now you can execute the ZigBeeSend command. There are several ways to send information to a node:
• Using its 802.15.4 MAC address (64b)
• Using its Network address (MY) (16b)
• Performing a broadcast transmission
Sending to Waspmote using its MAC address (64b):
$ ./ZigBeeSend -mac 0013a2004069165d “Hello Waspmote!”
Sending to Waspmote using its Net address (MY - 16b):
$ ./ZigBeeSend -net 1234 “hello Waspmote!”
Send to all the Waspmote devices at the same time - Broadcast mode:
$ ./ZigBeeSend -b “hello everybody!”
The source code “ZigbeeSend.c” and the reception program to be installed in Waspmote can be downloaded from the Meshlium
Development section: http://www.libelium.com/development/meshlium
You can download these files and change them in order to get new features and sending options.
Compilation:
The compilation can be done in the same Meshlium. Just copy these files in a folder accessing by SSH and execute:
$ gcc -o ZigBeeSend ZigBeeSend.c -lpthread
Important: If you want to create a “ZigBee sending” daemon that is executed each time Meshlium starts you have to deactivate the
“ZigBee Capturer” daemon (/etc/init.d/ZigbeeScanD.sh) as the ZigBee radio has to be used by one process at a time.
