Thanks - I think it'd help to see your code.
Sometimes if people are used to Arduino they'll write code like
while (Serial1.available()==0);- but that doesn't play well with Espruino and could cause issues if you were trying to do something like that? The best thing is to respond to data in theSerial1.on('data',...)handler.
