•
Tx Dropped – The number of packets to be transmitted over the air that were dropped by the
radio before sending. There can be various reasons for this. For example, an STFP message
could not be properly decoded by the radio, or a message could not be transmitted because the
radio is in an alarm state. Reference below for detailed information.
•
Header Bad – The number of packets to be transmitted over the air that were dropped by the
radio due to a bad STFP message header. The message may have a bad version or other invalid
field.
•
Invalid Slot – The number of packets to be transmitted over the air that were dropped by the
radio due to a bad Timeslot being specified. Valid timeslot values are 0 to N-1 where N is 8 times
the number of seconds in an epoch.
•
Too Long – The number of packets to be transmitted over the air that were dropped by the radio
due to a payload length that was too long. The maximum payload length is 133 without FEC, 117
with FEC.
•
Bad Freq – The number of packets to be transmitted over the air that were dropped by the radio
due to an invalid RX or TX frequency. Either the frequency was outside of the frequency range of
the radio (216.00625 to 221.9875 MHz) or the frequency has a bad step size.
•
In Alarm – The number of packets to be transmitted over the air that were dropped by the radio
while the radio was in alarm.
•
Msg Replaced – The number of packets to be transmitted over the air that were dropped by the
radio due to a later STFP message placing a new payload into that timeslot. This can be done
any time before the payload is queued up for transmission.
•
Too Old – The number of packets to be transmitted over the air that were dropped by the radio
because they were older than the configured Max Message Age. (Deprecated in release 1.2.8).
•
Force Key – The number of packets to be transmitted over the air that were dropped by the radio
because the radio was in Forced Key mode.
