ZigBee Link Testing with ZigBee Operator

ZigBee Operator support “Explicit Addressing ZigBee Command”. We can use Explicit Addressing ZigBee Command for link testing with API firmware.

Steps for Link Testing

Prepare the mesh network. The minimum requirement for a mesh network is a coordinator and an end device. We use a end device with API firmware.

Power on both coordinator and end devices. Connect the coordinator to the computer.

Open the ZigBee Operator and connect with serial port of XBee modules.

Go to “Tools-XBee Devices Properties” or “image ” icon to open Properties window and check “API” check box. Click “Read” button to make sure the computer can talk to device correctly.

Go to “Tools->Search XBee Devices” or click “image”icon to open “Search Device” window and check “API Mode”. Click “Search Network” button to search the network to make sure the end device are connected with Coordinator.

Click “Add To Database” button to add all XBee modules’ information to database.

Close the search window.

Click “View->XBee & XBee Pro ZB ZigBee” or “image” icon to switch to “Mesh Network” panel.

Select “Explicit Addressing ZigBee Command” in type

Select Coordinator’s address in Address

Set “Cluster ID” to 12 and “Source Endpoint” to E8 and “Destination Endpoint” to E8.

Set “Profile ID” to C105

Select “TEXT” in format and input “Echo” in RF Data. It can be any text as long as it is not empty.

Click “Send” button.

It will send the data to coordinator endpoint E8 from  source endpoint using cluster ID 12. This is setting for Loopback data. When coordinator received data from end point E8, it will send the data back.

Here is the data in log window.

Sometimes, the data send won’t be echo back. Please keep sending until you get the data back. Some times you need reset the end devices.

To check the signal strength on the remote module.

Switch to “Remote AT Command”, and select the address of the remote module and send “DB” Command. It will return the signal strength of last hop.
