Relay mode diagram:
When relay mode is used, the time-out (with respect to the transmitter) is not the same as with point-to-point
mode because of the additional time it takes to pass through intermediate nodes. The time-out specified by
RADIO_USER_TIMEOUT
is still applied, but it does not take relays into account. The time-out value will be
applied by the last relay before the end-point receiver (R2 Delta = Radio_User_Timeout).
The value of
RADIO_USER_TIMEOUT
applied by the last repeater is
configured in the transmitter, not in the repeater itself.
In relay mode, repeaters use the
RADIO_USER_TIMEOUT
value
encapsulated in the transmitter's frame. Repeaters only uses its own
RADIO_USER_TIMEOUT
setting when transmitting, not repeating.
In the above diagram, the value of
RADIO_USER_TIMEOUT
(set by the transmitter) corresponds to time
Delta R2
applied by Relay 2.
Delta 1
and
Delta R1
are evaluated by the corresponding radio module, depending on the number of relays
(repeaters), the type of wake-up, duration, and the values of
RADIO_USER_TIMEOUT
and
RADIO_ACKNOWLEDGE
.
