I have seen the schematics of CYBT-413034-EVAL which is present in the link https://www.cypress.com/documentation/development-kitsboards/cybt-413034-eval-ez-bt-module-arduino-evaluation-board
I have observed that R2 and R4 are mentioned as DNI. I searched and found on internet that it is "Do Not Install". I also noticed on the eval board that R2 and R4 are mounted.
You have mounted R2 and R4 in case they may be helpful to the user. Am I right.
Yes, it is for the I2C pull up usage.
