can any one worked on more than one uart?
i want to send and receive serial data from arduino by using more than one uart i:e i need to communicate with bluetooth, wifi, gsm, and also through internet please throw some light on this.. thanking you...
One way do that is to start & stop services as you need them.
i.e.
bluetooth.begin();
//do bluetooth stuff
bluetooth.end;
// start next service
wifi.begin();
// do wifi stuff
wifi.end;
etc.
Probably better off with multiple UARTs so any data that comes while you service another interface isn't lost.
