VL (Firmware Version - verbose) Command
AT Command: ATVL
Parameter Range: Returns string
Number of bytes returned: 2
<Diagnostics> VL Command is used to read the
verbose firmware version of the XTend Module.
Sample output: Firmware version 1.0, Jan 16
2005 10:46:57
VR (Firmware Version) Command
AT Command: ATVR
Binary Command: 0x14 (20 decimal)
Parameter Range (read-only): 0 – 0xFFFF
Number of bytes returned: 2
<Diagnostics> VR Command is used to read the
firmware version of the XTend Module.
WA (Active Warning Numbers) Command
AT Command: ATWA
Parameter Range: Returns string – one
warning number per line.
<Diagnostics> 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 (Active Warning Numbers) Command
<Diagnostics> WN Command is used to report
detailed 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 WN or WS
command, are not displayed. WN Command also resets all non-zero warning counts, except for
warnings that are presently active, which are set to 1.
Sample output: Warning 1: Under-voltage
3 occurrences; presently active
Warning 4: Over-temperature
5
occurrences;
presently
inactive.
AT Command: ATWN
Parameter Range: Returns string
Warning Number
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 the 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 user
custom configuration, or if no user-modifiable parameters have been modified from the compiled-in defaults. Note that modification of one or
more parameters without the subsequent ATWR to commit the changes to flash will not deactivate this warning, since it reflects the status of
the parameters in flash. Note as well 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.
