The first time I upload a program to the BLE nano, the program is uploaded correctly, but the Arduino IDE never stops saying it's uploading something.
And when I try uploading a second program I get the following error:
avrdude: ser_recv(): programmer is not responding avrdude: butterfly_recv(): programmer is not responding Problem uploading to board.
I have installed Arduino IDE version 1.6.3 and the following extension to allow compiling nRF51822 firmware: https://github.com/RedBearLab/nRF51822-Arduino
I have this problem on both Windows 7 and Windows 8.1
