set tx power level in nrf52810

No, do not provide this information here - this ticket is for another issue, which has been resolved - provide it in your active ticket on the subject.
Furthermore, please read my previous recommendation thoroughly. You should not just dump your code and say 'it is not working' - this is not very helpful, and it will take a lot of time to familiarize with, review, and understand what your issue is, before we may begin debugging to resolve the issue.
You should instead make sure to provide as much relevant information as possible, immediately, such as which debugging steps you already have taken, what you have observed, how it differed from what you would have expected, etc.

If you need a ticket or request to be handled urgently, please reach out to your Regional Sales Manager to discuss this - they are the only ones who may raise the priority of different tickets. If you do not know who your Regional Sales Manager is then you may send me a direct message with your location so that I may provide you with their contact information.

I will now close this ticket since the original issue has been resolved.

Best regards,
Karl
