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 modem is reset.
TT (Streaming Limit) command
<Networking and 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 modem is sending a continuous stream of RF data, a delay is inserted which stops its transmission and allows
other modems time to transmit (once it sends TT bytes of data). Inserted random delay lasts between 1 and 'RN + 1'
delay slots, where each delay slot lasts 38 ms.
The TT command can be used to simulate full-duplex behavior.
