Getting started with the XLR PRO RF Module
6. Range test data is represented in the chart. By default, 100 packets are sent for the test. XCTU
displays the instant local and remote RSSI in two separate controls, as well as the number of
packets sent and received. Remote devices only report their RSSI value when the local device
is operating in API mode (by setting AP to 1).
7. Watch the range test status indicators: RSSI will decrease the further away you are, and if you
continue to move the setup further away, eventually you will see the percentage of successful
packets drop below 100%, indicating you are approaching the limits of the range.
8. Click Stop Range Test to stop the process at any time.
