STATUS COMMANDS
Status Version Request
The OEM Host issues this command to request the
firmware and link status of the transceiver.
Check Status Registry
In firmware v2.2 and forward, the Status Registry
contains error codes which may be useful for the OEM
to note.
Note:
Bin Analyzer
The Bin Analyzer is a powerful command for
understanding the link conditions between two radios
over the entire frequency hopping spectrum. The Bin
Analyzer will cause the local radio to send an RSSI
request packet to the radio specified in the Destination
Address field. The remote radio will respond with RSSI
information and this is then streamed to the OEM
through the Serial UART. This sequence occurs once per hop.
Due to the random frequency hopping sequence of the
radios, it is not possible to associate a specific bin # with
a specific frequency, though the OEM can use the Bin
Analyzer response to identify any possible interferers and
to provide a quantitative analysis of the total number of
good versus bad bins.
The Bin Analyzer command will stream data results
back for each hop until the command is turned off or
the number of runs is met. The Bin Analyzer command
must be issued from Command Mode, but it will
continue to stream results back even after the OEM has
exited Command Mode. The Bin Analyzer packet is sent
as part of the RF Packet Header and does not affect the
throughput of data between two radios. See the RSSI
section of the manual for equations to convert RSSI to a
dBm value.
Read Temperature
The OEM Host issues this command to read the onboard
temperature sensor.

performing a calibration of the external crystal

Timer sleep mode. Although the radio is
not prevented from sleeping during calibration,
the calibration will be more accurate the longer

and still maintain sync with its Server.
