XTend™ RF Module ‐ Product Manual v2.x6x
RR (Retries) Command
RT (GPI1 Configuration) Command
SB (Stop Bits) Command
SH (Serial Number High) Command
SL (Serial Number Low) Command
<Networking & 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
(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.
<Serial Interfacing> The RT command is used to
set/read the behavior of the GPI1 ping (pin 10) of
the RF Module. The pin can be configured to
enable binary programming or RTS flow control.
<Serial Interfacing> The SB Command is used to
set/read the number of stop bits in the data
packet.
<Diagnostics> SH Command is used to set/read
the serial number high word of the RF module.
<Diagnostics> SL Command is used to set/read
the serial number low word of the RF module.
