Perform a range test
These instructions show you how to use the loopback cluster (0x12) when performing a range test.
The benefit of using this type of range test is you don't have to close the loopback jumper of the
remote module and the module can work in any operating mode.
1. In XCTU, open the
Tools
menu
and select the
Range Test
option.
The
Radio Range Test
window opens. Your local device appears on the left side of the
Device
Selection
area.
2. Select
XBEE_A
and click the
Discover remote devices
button
.
The discovery of remote devices starts. When the discovery process finishes, the other device
(XBEE_B) appears in the Discovering remote devices dialog.
3. Click
Add selected devices
.
4. Select
XBEE_B
from the
Discovered device
drop-down menu in the
Device Selection
area.

.
6. Click the
Start Range Test
button
.
7. If a notification dialog asks you to close the loopback jumper in the remote device, click
OK
.
