Hello VinayakMH, 

Here is my answer. 

I got the all TPHG (Temperature , Pressure , Humudity and Gas) values.  Kindly tell me the BSEC integration steps.

      I have 6 questions on this topic, as I mentioned below.

               1) As I have used your BOSCH BME680 drivers and wrote my own main.c in nRF52840-DK (Development Kit) and getting precise outputs                             of TPHG, so can I integrate BSEC directly to my project?

                - BME680 driver and BSEC library are different. If you want to use BSEC library, you should migrate BSEC library not BME680 driver. 

               2) If yes how can I integrate BSEC to my project? If no, kindly send me the steps to do it.

                - download bsec library https://www.bosch-sensortec.com/software-tools/software/bsec/

                - There are integration guide and example code. 

               3) So, after integrating BSEC to my project will i get the  precised converted values directly?or

                - Yes, please check example file. 

              4) Should i modify / develop my main.c code for BSEC? or

              5) According to my main.c should i modify / develop the BSEC?

                 - You should modify your main.c for sure. Also, you should configure some BSEC parameters in your main file. 

              6) Are there any steps to achieve it?  If any, kindly give me the hints or links to achive it.

                 - I already posted it. 

Thanks, 

[VinayakMH]
