RB (Packetization Threshold)
Command
command is used to set/read the
character threshold value.
RF transmission begins after
data is received in the DI Buffer
and either of the following criteria
is met:
• RB characters received by
the UART
• RO character times of
silence detected on the UART receive lines (after receiving at least 1 Byte of
data)
If PK (Max. RF Packet Size) is lowered below the value of RB, RB is automatically
lowered to match the PK value. If (RO = 0), RB bytes must be received before
beginning transmission.
Note: RB and RO criteria only apply to the first packet of a multi-packet transmission.
If data remains in the DI Buffer after the first packet, transmissions will continue in a
streaming manner until there is no data left in the DI Buffer (UART receive buffer).
RC (Ambient Power - Single
Channel) Command
command is used to examine
and report the power level on a
given channel.
Sample output: -78 dBm [when CF = 0]
4e [when CF = 1]
-78 [when CF = 2]
RE (Restore Defaults)
Command
is used to restore all configurable parameters to their factory default settings.
The RE Command does not cause default values to be stored to non-volatile
(persistent) memory. For the restored default settings to persis
t in the module‟s non-
volatile memory and be saved in the event of RF module reset or power-down, the
WR (Write) command must be issued prior to power-down or reset.
RM (Ambient Power - All
Channels) Command
is used to examine and report
power levels on all channels.
If no parameter is given, the
channels are scanned one time. If
a parameter is given, the
