Hello, Thanks for pointing out. As for me, I'm don't know much about I2C or Bus communication in detail which makes it difficult for me to solve this problem the way you described. I don't know hot to use a logic analyzer and also don't have one. Also, I didn't found any information on the internet on what an ACK is. Can you please point ot more precisely where the problem could lie? I looked at the code where the error is returned and don't know what I would have to change. Also, for Jetson Nano, I had to compile it without linking the WiringPi library (since it doesn't work on Jetson).
