0dBm or +4dBm? We need some advice to choose the right TX powerhttps://devzone.nordicsemi.com/f/nordic-q-a/59867/0dbm-or-4dbm-we-need-some-advice-to-choose-the-right-tx-powerHello, we need some advice to choose the right TX power. We still wonder if TX power +4dBm is the best choice or better use the default 0dBm. Here is some background: - In our embedded device, we are using Nordic nRF52832 and nRF5 SDK v16.0.0en-USTelligent Community 13Mon, 06 Apr 2020 06:56:30 GMTRE: 0dBm or +4dBm?

You should not run into trouble with certifications when using 0 or +4 dBm. The examples are set to use 0dBm TX power to have a default TX power for all examples.</p> <p>Best regards,</p> <p>Simon</p><div style="clear:both;"></div>RE: 0dBm or +4dBm?
