Hi Guys I have a Bluno which is an Arduino Uno compatible board with built in Blootooth 4.0
I am trying to create a protocol to control it from an Android smartphone.
I would like to know how to detect that it is connected.
Serial.available() simply returns true if there is something in the buffer Serial.begin(115200) returns nothing other than setting up the board so a repeat Serial.begin(115200) while connected will not help.
Any pointers would be appreciated
