WN (Warning Data) Command
<Diagnostics> WN command is used to
report the following data for all active
and sticky warnings:
• Warning number & description
• Number of occurrences since the last WN or WS command
• Whether the warning is currently active
Warnings, which are not currently active and have not been active since the last issuance
of the WN or WS commands, are not displayed. The WN command also resets all non-zero
warning counts; except for warnings that are presently active, which are set to 1.
Sample output: Warning 4: Over-temperature
5 occurrences; presently inactive.
Warning #
Description
1
Under-voltage. This is caused if the supply voltage falls below the minimum
threshold for the lowest power level (2.8 V). If/when the voltage rises above
the threshold, the warning is deactivated. The module will not transmit below
this voltage threshold.
2
Over-voltage. This is caused if the supply voltage exceeds 5.75 V.
Transmission is not allowed while this warning is active.
3
Under-temperature. This is caused if the temperature sensed by the module is
less than -40 C. The module does not artificially limit operation while this
warning is active, but module functionality is not guaranteed.
4
Over-temperature. This is caused if the temperature sensed by the module is
greater than +105 C. The module does not allow transmission nor reception
while this warning is active. The warning is deactivated when the temperature
falls to +100 C.
5
Power reduced. This is caused if the transmit power has to be reduced from
the level programmed by PL Command due to insufficient supply voltage. The
1 W power level requires 4.75 V or higher; 500 mW requires 3.0 V or higher;
100 mW, 10 mW and 1 mW require 2.8 V or higher.
6
Default calibration data in flash. This is caused if the module-specific power
calibration data is either not present or is invalid, or if none of the parameters
have been modified from their default values. Power levels may be incorrect.
7
Default configuration parameters in flash. This is caused if user-modifiable
parameters (i.e. those stored by a 'WR' command) in flash are all the
compiled-in default values. This is caused if the user configuration is found to
be not present or invalid at power-up and there is no custom configuration, or
if no user-modifiable parameters have been modified from the compiled-in
defaults. Modification of one or more parameters without the subsequent WR
to commit the changes to flash will not deactivate this warning, since it reflects
the status of the parameters in flash. Note that this warning does not reflect
usage of the custom configuration defaults, only usage of the compiled-in
defaults.
8
Default factory configuration parameters in flash. This is caused if the factory
parameters in flash are all the default values. This is caused if the factory
configuration is found to be not present or invalid at power-up, or if no factory
parameters have been modified.
