Start From Where?


Hi friends!

I will use Open AT SDK software firstly,I have just started with it and know nearly anything .And at this point I need ideas will guide me.

I want to learn :

1)How to download a code written before to wireless cpu and execute it.
(At this point I want to use firstly written ,example codes which works rightly.)

2)Then I want to learn writing codes which makes what I want

Which document or web adress you recommend me to realize above purposes?

And you recommend me where to start,thinking a person have no knowledge using Open AT SDK and its tools?


Best Regards.


I would suggest you read the tutorial in the documents folder of openat
and then if you are serious about openat then you should attend openat university training.
If you read all the post on this forum then you will see some people have written some code.
Best regards


Thanks walter-senekal…

I started reading the tutorial in the documantation.With being parallel to it I want to build and download the “Hello World” application.I built it with visula c++ 6.0 but compiler gave 5 errors and 1 warning.

Could you please tell me why this errors occured and what must be done in the program?Error and warning messages are below:

LINK : warning LNK4075: ignoring /EDITANDCONTINUE due to /INCREMENTAL:NO specification
LINK : error LNK2001: unresolved external symbol _opecCustomerTaskInit

Hi are trying to tun in debug mode make sure that you have started target monitoring tool before. cygwin and it must display

3.when you installed cygwin did you select all?


Dear Walter,

I installed cygwin with Open AT SDK and during installation selected all.

I didn’t understand clearly what you meant.You mean, it is necessary to start target monitoring tool before debugging.If you mean that,I didn’t start target monitoring tool before debugging.

And what must be done with cygwin?I don’t what to do with cygwin.I started it and it displayed Software Generation Toolkit.But else?For example if I will write command on cygwin,what are they?

If you explain what I will do step by step I will be very happy.

Best Regard…



Hi Ergün
" message in cygwin then it is fine and you do not have to do anything else with it.
To get back to RTE
you first have to start the TMT and sync with module before trying to run RTE

Best regards


Thanks Walter,

But I think I couldn’t tell where I have problems exactly.I mean, it is not understood I have problems at what point of my work.

I’m now trying to realize what the tutorial tells.
And I’m now at the point :“Generate and run Open AT applications in Remote mode”.I didn’t generate any code to download into the wireless CPU.That is ,my problem is related with generating the code.

Firstly I should generate it and then download it into wireless CPU.And then later step is using TMT.Isn’t it right?But now I think you are trying to help me using TMT.Am I right?

Best Regards…
