Hello,

I have not received any reply for more than 5 months. I am going to close this case. If you still need help, can reopen this one or create a new ticket mentioning the old one.

Thanks.

Hello,

Can you add CONFIG_BT_CTLR_TX_PWR_DYNAMIC_CONTROL=y int he prj.conf file?

One thing I am wondering how have you measured/checked power; is it by using command or using Spectrum analyzer or both?

Sorry for late reply. It's holiday time in Norway; so, this unwanted delay.

Hello,

Which specific samples form NCS you are working on, or it is your custom project?

Thanks.
