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 and 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.
AT Command: ATWA
Parameter Range:Returns string - one
warning number per line.
AT Command: ATWN
Parameter Range: returns string
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.
