I brought an A7 module but didn't find any code to use it. Is there any library for that anywhere?

Hi, does anyone have SDK for A7?

I notice several problems with different A7. 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:

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?

You should be able to use TinyGPS++. The NMEA stream is the same as always. HOWEVER! I have been playing unsuccessfully with the A7. I've got three: one "dead" as you describe, and the other two reboot every time I send an SMS from my cell phone to the module!

Verified: TinyGPS++ works with the A7.

Thank you :-) Is there any tutorial available for that?

Easy to use. Just send 


AT+GPS=1
AT+AGPS=1
AT+GPSRD=1

But does anyone know how to let the a7 put the NMEA sentences to the other uart port? Got some problems when using TinyGPS while gps is enabled

Hi, the string received starts with "GPRSD " word which is not expected by the read method
