For SL808XT and Q2698 modules, as the A&D service is emulated above the file system, this A&D volume is not statically configurable. All A&D data is stored in the file system. So by using AT+WOPEN=6,XXX and AT+WOPEN=9,XXX, A&D and file system area cannot be configured respectively. This command is not available for QCT modules.
AT+WOPEN=6,XXX //returns CME ERROR :3
AT+WOPEN=9,XXX //returns CME ERROR :3
• File system is present by default in these products and AT+WOPEN=9 returns the size of the file system partition and this partition is shared with A&D and flash objects.
