Chapter 13 – Specific AT Commands
Multi-Tech Systems, Inc. Wireless GSM/GPRS AT Commands (Document Number S000293I) 133
Wavecom Open AT Control Command +WOPEN
Description: This command starts, stops, deletes, and gets information about the current Open AT
®
embedded
application.
This command also allows you to erase the Open AT
®
flash objects storage place and to configure the
Application and Data (A&D) storage place size.
Values: <Mode>
0 Stop the Open AT embedded application. If this one was running, the product resets
1 Start the Open AT embedded application. If this one was stopped, the product resets
2 Get the Open AT library versions
3 Erase the objects flash of Open AT embedded application
4 Erase the Open AT embedded application
5 Suspend (in Wavecom software kernel) the Open AT embedded application tasks
6 If the (A&Dsize) parameter is used, configure the Application & Data storage size. Otherwise,
display the current A&D storage place size and Open AT application space size. If the A&D
storage place size has changed, the product resets.
Notes:
• For Mode=1: If the main version numbers returned by the AT+WOPEN=2 command do
not match, the command will reply +CME ERROR: 541.
• Mode=3 and 4 are only available only if the Open AT embedded application is stopped
(AT+WOPEN=0).
• Open AT embedded applications can be resumed with the AT+OPENRES command or
INTERRUPT feature (see +WCFM).
• Warning: With Mode 6, any A&D size change will lead to this area format process (this
process will take some seconds on start-up , before the +WIND:3 indication display (up to
1.5 seconds per 64 Kbytes flash sector size can be considered as a maximum; all A&D
cells data will be erased).
<IntVersion> ASCII string giving the internal Open AT library version.
<ExtVersion> ASCII string giving the external Open AT library version.
Note: If no embedded application is loaded, the <ExtVersion> parameter does not
appear.
<A&DSize> Usable only with <mode>=6
[0 -1344] Kbytes size allocated for the Application & Data storage place. Default = 768
Kbytes.
Provided parameter value will be updated with the nearest flash sector subdivision
(64 Kbytes). For example, if a 100 Kbytes size is required, a 128 Kbytes size will
effectively be set.
<OATSize> Returned with <mode>=6
Open AT Application reserved size (in Kbytes). This size is deducted from the
<A&Dsize> one, since the whole available size for Open AT and A&D storage
places are 1600 Kbytes (<OATSize> + <A&Dsize> = 1600).
