Failed to get/set TX power to NRF5340 as \v1.8.0\zephyr\samples\bluetooth\hci_pwr_ctrl

Hi 

As title. Thanks.

If I tried NRF52840, it's ok to get/set TX power.

Hi,

The nRF5340 supports up to 0 dBm output power in the register

In order to boost the output power, you should request a higher voltage in the VREGRADIO.VREQH
