How to set Transmit Power of my Advertisement Packet in nRF Connect SDK 2.5.1

[Sri1998]

Hello,

I want to set the transmitting power of the advertising packet. How can I set the TX power?

I am using nRF Connect SDK 2.5.1 in Visual Studio Code.

Regards,

Sri

Hi

I would suspect that the DCDC is not enabled. Can you share your custom board files(for vscode) and your config files?

PFA the contents of the custom board file and the config file of the project. 

File Name: Kconfig
Contents: 
# nRF52833 board configuration

config BOARD_ENABLE_DCDC
    bool "DCDC Mode"
    select SOC_DCDC_NRF52X
    default y
    depends on BOARD_BEACON_NRF52833
