hi, you can use the below AT commands to know the available memory size. ATI9: RAM/ROM size AT+WOPEN=6 : display the current A&D storage place size and application space size. AT+WOPEN=9 : display the current File System place size and the application space size. Also please note on AirPrime SL808xT & Q2698 embedded 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. For more information regarding Flash objects and memory you can refer AT command interface guide and ADL User guide for OpenAT application framework.
