Hi to all!!!, im having a really strange and confusing scenario. When i write and read in different cells i want to reallocate memory using the AT+WOPEN=6 command but when i do it supposely all the A&D memory shoul be erased. Strangely all the previous cells are there with the old data!!!. Shoul i format the memory?,if so, which is the safer path to do this?.

Thank u so much!!, im really lost with this.
