Hello, I have two xbee 802.15.4 modules: XB24-AUI001-revB and XB24-AWI-001 revB.

Modules connected to PC with RS232 adapter. I can read and write configuration parametrs with X-CTU, and send data between modules without any problems. But when I’m trying perform loop back range test in X-CTU, modules successfully talk to each other only on range less than 5-6 meters.

P.S.: One module has whip antenna, other one has external antenna trough U.FL. to RPSMA connector.

Make sure that you’ve set your timeout to 5000ms instead of the default (1000ms). You can do this in XCTU -\> Range Test -\> Advanced \>\>\> -\> Data Receive Timeout.
