I want to set the TX power in the bluetooth/peripheral_uart example.
I looked through the other posts with similar questions but can't find a working solution.
I don't want to set it dynamically with HCI commands. Instead I would like to just set in in the prj.conf file.
According to this documentation I have to use the following commands to increase the TX power for a nrf5340 chip.
CONFIG_BT_CTLR=y
CONFIG_BT_CTLR_TX_PWR_PLUS_3=y
Apparently I also need to switch from the Nordic Softdevice Controller (SDC) to the Zephyr BT Controller according to this link. After doing that, I still only get warnings and I can't finish a pristine build.

I'm a bit lost as other commands like "CONFIG_BT_CTLR_TX_PWR_ANTENNA =8" or "CONFIG_BT_CTLR_TX_PWR_PLUS_8" also don't work.
The only other thing that I could try would be to use the net core of the chip as hinted at at this link:
However, that would be a lot of work and I was wondering if it's possible to only use the app core in some way.
I would be very appreciative for some help!
