A non-zero value defines the time that PWM output is active with the RSSI value of the last received RF packet. After
the set time when no RF packets are received, PWM output is set low (0 percent PWM) until another RF packet is
received. PWM output is also set low at power-up. A parameter value of 0xFF permanently enables PWM output and
always reflects the value of the last received RF packet.
The Config/RSSI pin is shared between PWM output and Config input. When the module is powered, the Config pin is
an input. During the power-up sequence, if RP 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

<Networking and Security> The 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 (acknowledgments) 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 acknowledgment from a receiving
module. If the acknowledgment 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 acknowledgment is received or
until the packet is sent RR times.
AT Command: ATRR

RT (GPI1 Configuration) Command

<Serial Interfacing> The RT command is used to set/read the behavior of the GPI1 pin (GPI1) of the OEM RF Module.
The pin can be configured to enable binary programming or RTS flow control.
