Hello, I keep getting this error "not in sync: resp=0x00" when I try to upload sketch to a arduino nano. I followed this tutorial Arduino Programming | Introducing Bluefruit EZ-Link Breakout | Adafruit Learning System and double checked the wiring, everything seems to be fine, and I use Mac to connect it it says connected, and in the IDE tool menu, I make sure I chose Arduino Nano, for the port I chose HHW-UART-S10. What else could be wrong? Thanks
"old bootload option in the chip menu"? what and where is that? Do you mean Tools-->processor? In that I have ATmega328P selected which works perfectly fine when use the USB cable.
OK - you did install the correct capacitor in the correct orientation on the correct pin?
Yes I installed a 1 uf cap as instructed in the tutorial with + goes to RST on the Arduino. I also tried to reverse it, the still the same error.
BTW, I got the EZ-Link a year or so ago. I have never been able to get it to work.
I also tried to upload on a Windows 10 machine, but with the same error with a different address 0x59. What might couse this "not in sync: resp=0xXX" problem any way
Yes, when I used the clumsy USB cable, I have no issue uploading at all.
I have two EZ-link break outs and 2 EZ-Link shields for Uno. only one shield works.
There are many questions online regarding this issue - “not in sync: resp=0xXX”, but the more I read the more confuse I get, what exactly causes this any way, the EZ-Link? Have anyone else had success using it?
What are the RX and TX lights on the Arduino UNO doing during the upload process?
As the Rx and Tx LEDs are controlled by the 16u2, probably nothing.
Oops! You're right. Ignore that request (unless the EZ-Link has RX and TX lights)
