Hi thnx a lot for the reply… but what i ve to do at that time to subscribe any A&D memory

If there is no A&D memory, then you obviously can’t subscribe it!

I don’t know if it’s allowed to send the necessary AT+WOPEN command from within your Open-AT application - but I very much suspect not!

I very much suspect that you have to ensure that the A&D size is correct before you start you application…

Your application could use adl_adGetState to verify the availability of A&D storage - and give an error if it’s not as required…
