I am going to develop a midi controller that is made with and arduino and a module ESP8266.
I wish control the system with smartphone: that's way I need ESP8266.
But I want to connect my system to a midi keyboard.
Is it possible to develop a system considering the single uart interface (tx and rx) used for both the ESP8266 and midi in/out?
If no, is there an arduino card with two od more uart interfaces?
thanks in advance
