PW (Pin Wake-up) Command
RB (Packetization Threshold) Command
RE (Restore Defaults) Command
Command Summary
Description
AT Command: ATPW
<Sleep (Low Power)> Under normal operation, a module in
Cyclic Sleep Mode cycles from an active state to a low-power
state at regular intervals until data is ready to be received. If
the PW Parameter is set to 1, SLEEP (pin 2) can be used to wake
the module from Cyclic Sleep. If the SLEEP pin
is de-asserted (low), the module will be fully operational and
will not go into Cyclic Sleep. Once SLEEP is asserted, the
module will remain active for the period of time specified by ST
(Time before Sleep) Command, and will return to Cyclic Sleep
Mode (if no data is ready to be transmitted). PW
Command is only valid if Cyclic Sleep has been enabled.
Binary Command: 0x1D (29 decimal)

Command Summary Description
AT Command: ATRB
<Serial Interfacing> RF transmission will
commence when data is in the DI Buffer
and either of the following criteria are
met:
• RO times out on the UART receive lines
(ignored if RO = 0)
• RB characters have been received by
the UART (ignored if RB = 0)
If PK is lowered below the value of RB; RB
is automatically lowered to match PK.
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 streaming
manner until there is no data left in the
DI Buffer (UART receive buffer).
Binary Command: 0x20 (32 decimal)
Parameter Range: 0 – 0x100 [Bytes]
(Maximum value equals the current value
of PK Parameter (up to 0x100 HEX (800
decimal))
Default Parameter Value: 1
Number of bytes returned: 2
Related Commands: PK (RF Packet Size),
RO (Packetization Time out)
This command is only supported on S3B
modules.
Command Summary
Description
AT Command: ATRE
<Diagnostics> RE Command restores all
configurable parameters to factory
default settings. However, RE Command
will not write the default values to
non-volatile (persistent) memory. Unless
the WR (Write) Command is
issued after the RE command, the
default settings will not be saved in the
event of module reset or power-down.
Binary Command: 0x0E (14 decimal)
