yes, port config is ok.
i have 12 modules, from two diff suppliers. Only one module doesn't accept AT commands. Reset is ok, I can trace traffic but when I try simple "AT\n\r" nothing hapends ... as port were dead, burned out (URTX). I used Logic analyzer to check the signal from connector to the chip .. null, nil, nada ... like there is none.
Beside those A7 I have they react differently at Reset ... pull down circuit with N-MOS Fet ... sometimes POWER LED turns OFF, sometimes not. Sometimes A7 booted, sometimes not.
Another problem I have is:
- Phone book Write Command: AT+CPBW=index,"<number>",129,"name"
if there is no index field supplied by write command A7 doesn't accept this entry and reboots
- Phone book Find Command: AT+CPBF="search string" A& performs searching only bye name not also by number
- AT+CLIP=1 displays only the caller number and not also his name from phone book (???)
I don't know if I have the last Revision? Support from A7 doesn't responds to my emails.
Therefore I would also like to have A7 SDK!
With failures like this, we should have a A7 Errors forum.
knowing how to avoid those failures, working with A7 is good. But not perfect
What is your experience with A7?

Daniel
It would be great if we could use it
