5.3.4 Diagram of a polling mode exchange
This diagram shows a typical case where remote Wavecards communicate with their respective hosts. When
sending a GET_TYPE request (see chapter 4) in polling mode, remote Wavecards respond without
preliminary dialogue with their host.
POLLING_TIME : a time-out is started (set by POLLING_TIME) after the radio frame is transmitted. If
modules do not respond before the end of the time-out (by default 1 second), then the transmitter sends the
same radio frame to the next remote module. If the previous remote module responds after the time-out, its
response frame is lost.
The POLLING_TIME parameter can be modified using parameter setting commands.
