Problems using adl_adGetState


Hi to all!!, i want to know the free space i have left in the A&D using adl_adGetState function. The return value i got is ADL_AD_RET_ERR_NOT_AVAILABLE wich for my knowledge it means that there is no A&d memory left. Strangly i didnt write in any cell or anything, and i reserved A&D memory whit the WOPEN command (AT+WOPEN=6,500).

Does anyone the answer??. Thank u so much for advance.
