I followed your instructions. It worked. I was able to get the Bluo app to talk to Serial monitor.
If I run my own sketch, the Blueduino will only transmit data if I print to Serial1 AND Serial.
And it only transmits data if I first open serial monitor and then close serial monitor.
If I just print to Serial1, the Blueduino won't transmit. And if I print to Serial1 AND Serial, but I don't open and close serial monitor, the Blueduino won't transmit either.
It seems like Serial needs to be activated before Serial1 will activate.
This won't work for a standalone project where the Blueduino isn't connected to a computer.
What do you suggest?
I'm on firmware 2.1.5
