ST (Time before Sleep) Command
<Sleep Mode (Low Power)> The ST
Command is used to set/read the
period of time (in milliseconds) in
which the RF module remains
inactive
before entering Sleep Mode.
For example, if the ST Parameter is
set to 0x64 (100 decimal), the
module will enter into Sleep mode
after 10 seconds of inactivity (no
transmitting or receiving).
This command can only be used if Cyclic Sleep or Serial Port Sleep Mode settings have
been selected using SM (Sleep Mode) Command.
TP (Board Temperature)
Command
<Diagnostics> TP Command is used
to read the current temperature of
the board. Sample Output:
26 C [when
ATCF = 0]
1A [when ATCF = 1]
26 [when ATCF = 2].
TR (Transmit Error Count)
Command
<Diagnostics> The TR command is
used to report the number of
retransmit failures. This number is
incremented each time a packet is
not acknowledged within the number
of retransmits specified by the RR
(Retries) parameter. The number of
packets therefore are counted that
were not successfully received and subsequently discarded.
The TR parameter is not non-volatile and is reset to zero when the RF module is reset.
TT (Streaming Limit) Command
<Networking & Security> The TT
command is used to set/read the
limit on the number of bytes
that can be sent out before a random
delay is issued.
If an RF module is sending a
continuous stream of RF data, a
delay is inserted which stops its transmission and allows other modules time to transmit
(once it sends TT bytes of data). Inserted random delay lasts between 1 & 'RN + 1' delay
slots, where each delay slot lasts 38 ms.
