I have my Arduino Nano connected to the HC-06 module (with the RX/TX pins).

My issue is that when I try to upload new code to my Arduino (via the Arduino IDE, through the USB connection) the Arduino IDE doesn't succeed.

I get this error:

avrdude: stk500_getsync() attempt 1 of 10: not in sync: resp=0x00

I believe that it is just trying to upload the code to the HC-06 (instead of the Arduino). Is there a way to overcome this issue?.

Thanks.

Note: I found this entry https://stackoverflow.com/questions/27175937/arduino-program-upload-while-btooth-module-connected-avrdude-stk500-getsync indicating that it wasn't possible (that I need to unplug the module). I am trying to confirm it.

The link in question was correct... you do need to unplug it.

The Arduino's serial chip uses pins 0 and 1 to communicate with the ATmega 328 PU chip onboard, thus you have two independent devices connected to the same wires and both the Arduino main chip and the Bluetooth module are trying to communicate at the same time (rendering all data unreadable by the computer).
