Hi Tilen.

Firstly, thanks for your work on this project. It's awesome. I'm trying testing your project with my devices, and there is a problem as the tittle. The debugging shows: "GSM commands parser; Compiled: Feb 10 2017 08:50:18 GSM Init status: 0 Call disconnected, trying to call someone! Calling! Call finished!" Then I used USB to UART converter to test with module SIM, it works normally. I'm using F429 Discovery, module SIM800A, and CALL_RTOS_EXAMPLE. Could you tell me what problem is in my case? Is it an issue? Or you just make it like this?

Thankyou very much. Regards, Vinh.

In my case this happened too. It was because usb can give only 500mA but sim can use up to 2A in some cases.

Increase power and try again.

Yes, I used the external power. But now it works well. Maybe because of some problem with the power. Thankyou very much for your help.
