Hmm, that almost sounds like your board is faulty... If you have a scope or LA, you can see if there actually are signals on the SCL/SDA pin, but if not, I'd contact wherever you got this board from, to see if you can get a replacement.

@ESP_Sprite Sorry for late reply. I saw your reply yesterday because this forum ui confused me a little and your reply was on the page 2 and I thought all the replies will be in the same page.

I bought a USB logic analyzer, i dont know how to debug it with this board. can you guide me or give me some links to go through on how to setup this.
