Hi Sergei,

Thanks for your response.

Please find code I found from Internet attached,

On which serial device is your modem connected? The code indicates /dev/ttyUSB3 . Did you copy this or insert it because you know it to be correct?

Sorry for not being clear, the /dev/ttyUSB3 is a debug port for uBlox SARA EVK, I was able to use minicom to connect to /dev/ttyUSB3 and to get all AT command response.

If it's correct, what permissions are set on that device?

The permission was setting to only allow root access, so I ran both minicom and application in sudo, "sudo ./stream", if that is a problem, I'll change the access permision to user mode.

$ ls -l /dev/ttyUSB3 crw-rw---- 1 root dialout 188, 3 Jan 22 11:26 /dev/ttyUSB3

Thank you very much. Kind regards, - jh
