XTend™ RF Module ‐ Product Manual v2.x6x
TR (Transmit Error Count) Command
TT (Streaming Limit) Command
TX (Transmit Only) Command
VL (Firmware Version - Verbose)
VR (Firmware Version - Short) Command
<Diagnostics> The TR command is used to report
the number of retransmit failures. This number is
incremented each time a packet is not acknowl-
edged within the number of retransmits specified
by the RR (Retries) parameter. The number of
packets therefore are counted that were not suc-
cessfully received and subsequently discarded.
The TR parameter is not non-volatile and is reset
to zero when the RF module is reset.
<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 trans-
mission and allows other modules time to trans-
mit (once it sends TT bytes of data). Inserted
random delay lasts between 1 & 'RN + 1' delay slots, where each delay slot lasts 38 ms.
The TT command can be used to simulate full-duplex behavior.
<RF Interfacing> The TX command is used to set/
read the transmit/receive behaviors of the RF
module. Setting a module to TX-only (TX = 1)
may reduce latency because the transmitting
module will never be confined to receiving data
from other modules.
<Diagnostics> The VL command is used to read
the verbose firmware version of the RF module.
<Diagnostics> The VR command is used to read
the firmware version of the RF module.
Note: Firmware versions contain four significant
digits - “A.B.C.D”. If B=2, the module is pro-
grammed for operation in Australia only.
