I have a need: Build a system that allows a offline terminal(it´s a PC) to connect to a server. to do this, we decided to upload the data to a android 3G smartphone and, by network, send the data to the server, retrieve the response and send to terminal. See the scheme below:
GOING TERMINAL --(?)--> Android App --(HTTP)--> Server
BACK Server -- (HTTP) --> Android App --(?)--> Terminal
We have some constraints:
1 - The terminal becomes locked until the android send the response from server (It´s a sync message) 2 - We have only text content. 3 - The place where the terminal is connected does not have network signal. 4 - We have to provide a minimum security level possible. 5 - The terminal app will be developed using PHP.
So, my question is: i have to connect the terminal to pc to send and retrieve information from a android phone. Should i use bluetooth or build a wi-fi network (with android phone built-in feature) to connect them?
Did someone have this problem?
