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:

Hello

I have shared the custom board files and the config files.

Hi

I looked over and they seems fine to me. 

I got a few pointers from a collauge that is worth having a look at

1. The PPK2 may give some spikes when changing level

2. You should zoom in where the adv.evt is and look at the level where is stable

Regards

Hello,

I have looked into the adv.evt in the PPK current consumption by zooming in and found three peaks. But all the peaks are above the value mentioned in the datasheet even excluding the peak at the start.

So is there anything I can do to reduce or do you think the PPK is giving the spikes in current consumption?

TIA

[Sri1998]

The stable current is only high. So I presume DC/DC mode is not activated. So am I missing anything in enabling the DCDC mode?

Regards,

Sri
