Ping Pong Test
Ping-Pong has automatically started after the Automatic Frequency Control. At this stage the user
observes that the Tx yellow LED blinks (Ping). The Rx yellow LED comes on when the received
message is correct (Pong).
A reliable two way radio link has been established between two modules. Each module, upon receipt
a valid radio frame will immediately “echo back”, keeping the Ping-Pong test sequence continually
active. This indicates the desired state of 100% two-way communications reliability.
