ST (Time before Sleep)
Command
The ST
command is used to set and read
the period of inactivity (no serial or
RF data is sent or received) before
activating Sleep Mode.
NonBeacon Firmware
Set/Read time period of inactivity
(no serial or RF data is sent or
received) before activating Sleep
Mode. ST parameter is only valid with Cyclic Sleep settings (SM = 4 - 5).
Coordinator and End Device ST values must be equal.
T0 - T7 ((D0-D7) Output Timeout)
Command
The T0, T1, T2, T3, T4, T5, T6 and
T7 commands are used to set/read
output timeout values for the lines
that correspond with the D0 - D7
parameters. When output is set (due to I/O line passing) to a nondefault level, a timer
is started which when expired, will set the output to its default level. The timer is reset
when a valid I/O packet is received. The Tn parameter defines the permissible
amount of time to stay in a non-default (active) state. If Tn = 0, Output Timeout is
disabled (output levels are held indefinitely).
VL (Firmware Version - Verbose)
The VL command is
used to read detailed version
information about the RF module.
The information includes:
application build date; MAC, PHY
and bootloader versions; and build
dates.
VR (Firmware Version) Command
The VR command is
used to read which firmware version
is stored in the module.
Version numbers will have four significant digits. The reported number will show three
or four numbers and is stated in hexadecimal notation. A version can be reported as
"ABC" or "ABCD". Digits ABC are the main release number and
D is the revision number from the main release. "D" is not required and if it is not
present, a zero is assumed for D. "B" is a variant designator. The following variants
exist:
• "0" = Non-Beacon Enabled 802.15.4 Code
• "1" = Beacon Enabled 802.15.4 Code
