RR (Retries) Command
RS (RSSI) Command
© 2008 Digi International, Inc.
Networking> RR Command specifies the
number of retries that can be sent
for a given RF packet. Once RR Command
is enabled (set to a non-zero
value), RF packet acknowledgements and
retries are enabled. After transmitting
a packet, the transmitter will wait to
receive an acknowledgement
from a receiver. If the acknowledgement
is not received in the period of
time specified by the RN (Delay Slots)
Command, the transmitter will transmit
the original packet again. The packet will
be transmitted repeatedly
until an acknowledgement is received or
until the packet has been sent RR
times.
Note: For retries to work correctly, all
modules in the system must have
retries enabled.
Description
Description
<Diagnostics> RS Command returns the
signal level of the last packet
received. This reading is useful for
determining range characteristics of the
modules under various conditions of
noise and distance.
Once the command is issued, the
module will return a value between 0x6
and 0x36 where 0x36 represents a very
strong signal level and 0x4 indicates
a low signal level.
