CONFIG_OPENTHREAD_DEFAULT_TX_POWER Usage and Effects

[Woobin Song]

Hi Noridic team,

I have enabled Matter over Thread on the nRF5340. In this setup, I'm planning to reduce the TX power by setting CONFIG_OPENTHREAD_DEFAULT_TX_POWER=0. Apart from transmission power and current consumption, does this setting affect anything else?
I am currently using NCS version 2.6.2, and the default value of CONFIG_OPENTHREAD_DEFAULT_TX_POWER is 3.

config OPENTHREAD_DEFAULT_TX_POWER
    default 20 if MPSL_FEM
    default 3 if SOC_SERIES_NRF53X
    default 8 if SOC_SERIES_NRF52X

BR,

Our product is a digital door lock, so high transmission speed is not a critical factor like it would be in a real-time game. Therefore, we don't expect any major issues. We will test the range for different TX power values, as you advised.
