WA (Active Warning Numbers) Command
<Diagnostics> The WA command reports the
warning numbers of all active warnings - one
warning number per line. No further information
is shown and warning counts are not reset.
Sample Output (indicates warnings 1 and 3 are currently active):
1
3
OK
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.
WR (Write) Command
<(Special)> The WR command is used to write
configurable parameters to non-volatile memory
(Values remain in the modem's memory until
overwritten by another use of WR Command).
If changes are made without writing them to non-volatile memory, the modem will revert back to
previously saved parameters the next time the modem is powered-on.
If the non-volatile user configuration is not correct, WR will re-attempt (up to 3x). If all three
attempts fail, the command will return an ERROR alert.
WS (Sticky Warning Numbers) Command
<Diagnostics> The WS command reports warning
numbers of all warnings active since the last use
of the WS or WN command (including any warn-
ings which are currently active). This command
also resets all non-zero warning counts, except
for warnings that are presently active, which are set to 1.
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.
