Cannot upload sketch when JY-MCU bluetooth is on.

Hi everyone,

I have one of those $6 JY-MCU bluetooth adapters, running Firmata, which listens to the serial port. When this adapter is connected, I cannot upload sketches using the USB port. It works only when I disconnect it and press reset on the Arduino.

Any ideas on a workaround?

The USB port is connected to the serial port. If you have something else plugged into the serial port it may well interfere with uploading.

That makes sense. I am wondering if there is any workaround, like switching off the Bluetooth module for a couple of seconds.
