PROTOCOL_UNKNOWN_ERROR
430h This is an error returned by
ThingMagic Nano when no more
error information is available
about why the operation failed.
Check the data that is being written
and where it is being written to in the
command resulting in this error. Try
with a different tag.

FAULT_AHAL_INVALID_FREQ 500h A command was received to set a
frequency outside the specified
range.
Check the values you are trying to set
and be sure that they fall within the
range of the set region of operation.
FAULT_AHAL_CHANNEL_OCCUPIED 501h With LBT enabled an attempt was
made to set the frequency to an
occupied channel.
Try a different channel. If supported
by the region of operation turn LBT
off.
FAULT_AHAL_TRANSMITTER_ON 502h Checking antenna status while
CW is on is not allowed.
Do not perform antenna checking
when CW is turned on.
FAULT_ANTENNA_NOT_CONNECTED 503h An attempt was made to transmit
on an antenna which did not pass
the antenna detection when
antenna detection was turned on.
Connect a detectable antenna
(antenna must have some DC
resistance). (Does not apply to
ThingMagic Micro or ThingMagic
Nano; they do not detect antennas.)
FAULT_TEMPERATURE_EXCEED_LIMITS 504h The module has exceeded the
maximum or minimum operating
temperature and will not allow an
RF operation until it is back in
range.
Take steps to resolve thermal issues
with module:
• Reduce duty cycle
• Add heat sink
FAULT_POOR_RETURN_LOSS 505h The module has detected a poor
return loss and has ended RF
operation to avoid module
damage.
Take steps to resolve high return loss
on receiver:
• Make sure antenna VSWR is
within module specifications
• Make sure antennas are
correctly attached before
transmitting
• Check environment to ensure no
occurrences of high signal
reflection back at antennas.
FAULT_AHAL_INVALID_ANTENA_CONFIG 507h An attempt to set an antenna
configuration that is not valid.
Use the correct antenna setting or
change the reader configuration.
