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? Regards Runar

Good I see Ketil has been assigned to the case. Let's wait and see what his feedback is. You could also link the current plots to him Regards Runar

If I add CONFIG_SOC_DCDC_NRF52X=y in the kconfig file then it is saying

Fullscreen

XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX

error: SOC_DCDC_NRF52X (defined at soc/arm/nordic_nrf\nrf52\Kconfig.soc:85) is assigned in a
configuration file, but is not directly user-configurable (has no prompt). It gets its value
indirectly from other symbols. See
http://docs.zephyrproject.org/latest/kconfig.html#CONFIG_SOC_DCDC_NRF52X and/or look up
SOC_DCDC_NRF52X in the menuconfig/guiconfig interface. The Application Development Primer, Setting
Configuration Values, and Kconfig - Tips and Best Practices sections of the manual might be helpful
too.

So any other way to enable the DCDC mode?

Sorry, I gave the wrong link. You need CONFIG_BOARD_ENABLE_DCDC=y

if I add "CONFIG_BOARD_ENABLE_DCDC=y" to the proj.cofig it is showing below error:

Fullscreen
XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
warning: attempt to assign the value 'y' to the undefined symbol BOARD_ENABLE_DCDC

I have created a new board in NRF Connect for the board I am using. Do I need to do anything different because it has a different device tree file?

Regarding the power modes I want to measure current consumption in "ION_RAMON_RTC", "ION_RAMOFF_RTC", "ION_RAMOFF_EVENT". Since my application is beacon I don't need to remember anything so I can turn off the RAM. I want to try all the three modes. Can you suggest a reference code to put the device in the before mentioned states?

Could you share your board files so that I can have a look at them?

Did you do as in step 6 here? If not, try to do it and see if it works

I will need to check regarding ION_RAM_OFF and so on as I have never seen it used. But you could also check out https://docs.nordicsemi.com/bundle/ncs-latest/page/nrf/libraries/others/ram_pwrdn.html
