parameter is a non-zero value, the Config pin is configured as an output and set low
until the first RF packet is received. With a non-zero RP parameter, the Config pin is
an input for RP ms after power up.
RR (Retries) Command
RR command is used to set/read
the maximum number of retries
sent for a given RF packet.
When RR Command is enabled
(RR>0), RF packet retries and
ACKs (acknowledgements) are
enabled.
Exceptions: If the MT command in enabled (MT>0) or if a broadcast Destination
Address is used (DT = 0xFFFF); RF packet retries and ACKs are disabled.
After transmitting a packet, the transmitting RF module waits to receive an
acknowledgement from a receiving module. If the acknowledgement is not received in
the period of time specified by RN (Delay Slots) Command, the original packet is
transmitted again. The RF packet is transmitted repeatedly until an acknowledgement
is received or until the packet is sent RR times.
RT (GPI1 Configuration)
Command

behavior of the GPI1 pin (pin 10)
of the OEM RF Module. The pin
can be configured to enable
binary programming or RTS flow
control.
SB (Stop Bits) Command
Command is used to set/read
the number of stop bits in the
data packet.
