Hello, please I would like to know if it is possible to design a smartphone to udoo x86 able to make a call by: 1) installing Android on udoo x86 . 2) connecting a gsm module to udoo . 3) creating a app able to interact with the gsm module over the android operating system. I had to do research on the Internet, but in the results of this research, it was done by ordering the app on a smartphone itself connected to udoo via USB, but I want to order the app directly on the touch screen of the udoo. A bit like on a smartphone. Thanks in advance for your answers.
