The first Ping Pong demonstration allows RF communication between two points to be achieved. The
communication is made between a board operating as Master and a board operating as a Slave. In
addition two operating modes are available: Automatic and Manual.
With the Automatic mode, the Master sends a message to the Slave every 125ms and changes
transmission frequency after 1s (Auto-jump). When the Master receives an acknowledge message
from the Slave or when the Slave receives a message from the Master, the Rx yellow LED lights up
(Communication OK).
The Manual mode is the same as Automatic mode. The main difference is the selection of the
frequency. In this case a user selects the frequency by pushing on the "Frequency Selection" button.
