Hi, I'm having trouble connecting the Arduino IDE to my Bittle on NyBord v1_1. I am able to control the Bittle via the iPhone app with the bluetooth adapter so I know the hardware works. I am also able to upload sketches and communicate via the usb serial connection. I can connect to the bluetooth adapter via MacOS Bluetooth settings. I can even see the serial port in the Arduino IDE: However, when I try to upload the sketch. I get this error: Sketch uses 31290 bytes (97%) of program storage space. Maximum is 32256 bytes. Global variables use 1102 bytes (53%) of dynamic memory, leaving 946 bytes for local variables. Maximum is 2048 bytes. avrdude: stk500_recv(): programmer is not responding avrdude: stk500_getsync() attempt 1 of 10: not in sync: resp=0x00 avrdude: stk500_recv(): programmer is not responding avrdude: stk500_getsync() attempt 2 of 10: not in sync: resp=0x00 ... avrdude: stk500_getsync() attempt 10 of 10: not in sync: resp=0x00 Failed uploading: uploading error: exit status 1 How can I debug this. Am I missing a configuration somewhere?
