I tested the driver in your link with an OLED screen I found here at the office and I couldn't make it work either.

Then I tested this code and if I comment out the BLE stuff it works right out of the box (SDK 12.2.0). I suggest you try that one instead.

Your code looks pretty much identical to the code in the github repository you linked to, and I assume that should work.

I don't know anything about the SSD1306 driver and I don't know what OLED screen you are using, but if you are indeed able to get a response form the screen then maybe it is just a matter of power. At least this OLED screen seems to have some special power needs.

Yes I am able to get response from the OLDE screen..

will you check my code is right or not?

If yes, you are probably using the SSD1306 drivers wrong. what does it mean?

Are you able to get a response from the OLED screen with the TWI Scanner example? If not you probably have an issue with pin numbering, power supply, or some other HW issue. If yes, you are probably using the SSD1306 drivers wrong.
