Hi, anyone knows how to keep traces in a modem GPRS Wismo M1306B?  
I want that when i am not in the target monitoring tool, the traces can keep itself in the modem or in a pc.  
I am programming in C using adl library and I have seen the Error managment point but i don’t know how to use it.

Thank you.

Hi nebuchanazer,

I don’t know which version of OpenAT you are using but in the 4.0, you have a sample wich handle backtraces using adl. See bug sample.

Good luck

Regards,

Thanks. I was with the bug sample, but i don’t really understand how it works. Maybe it waits for a fail and then it downloads the traces to some place in my pc? but where? and how can i see those traces?
