Have anybody an exemple of battery charger in openAT software?
Look at the Application Notes…
Yes, I look there but I couldn’t find anything. I’m trying to undestand, how can I program battery managment by using open AT libraryies, but I have some erros.
Anna.
Yes, I know - but you haven’t answered my question yet: viewtopic.php?f=36&t=4470&p=17997#p17998
There’s no point going off on a tangent before you know what the actual problem is!
There is no spedific API for battery charging; so you just have to use AT Commands. 
See: viewtopic.php?f=3&t=3595
If you have +CME ERRORS, then those are responses to the AT Commands; they have nothing specifically to do with Open-AT or ADL - you would get exactly the same response if you entered the same command manually at the same point;
If you have error results in the API return codes, then the code tells you what the error is - and it probably has nothing to do with the spedific AT command.
The AT Commands User Guidelines document has a whole chapter describing the charging process - including an example of using the AT Commands, and interpreting the Responses.

The document is listed right at the bottom of the Application Notes page as “AT implementation of GPRS, PLMN, AEC, Battery & USSD”.
Hiya,
Just to make it obvious: There is NO API for battery management - you have to write your own state machine routine to manage battery states, and use the AT commands referred to by awneil to control the battery charger sub-system.
Once you do that, it all works reasonably well…
ciao, Dave
Alternatively, just use an external battery charger…
