Upload error to UNO

UNO has been working fine and even added Bluetooth module to it. But within the last week it no longer uploads programs. This is with the IDs in W10 and I tried it from a pi3 and got it to upload successfully one time. The error I get each time is:

Using Port : COM3
Using Programmer : arduino
Overriding Baud Rate : 115200
avrdude: stk500_recv(): programmer is not responding
avrdude: stk500_getsync() attempt 1 of 10: not in sync: resp=0xcd
avrdude: stk500_recv(): programmer is not responding

until it times out at 10 of 10 attempts. I've gone through and disabled all Bluetooth drivers, uninstalled drivers and Blue soliel just in case that was a conflict in windows but no difference. Same problem in the pi 3 as well.

Disconnect the bluetooth module from pins 0 and 1 of the Arduino - those pins are used for serial upload, and uploading a sketch will fail when there's an external device on those pins.
