Maximum allowed TX power

[Øyvind]

I'm developing a product with the nRF52840 using nRF_SDK 15.0.0 and s140 v6.1.0. Since my device is not power constrained, I want to maximize the range, so I use Coded PHY, the default packet lengths and increase TX power.

Are there any regulatory limits to the TX power I can use with the SoftDevice? I do not use any PA/LNA, and I have a PCB antenna, the same as the devkit.

Hi Øyvind

The output power is limited to 10 dBm / 1 MHz in Europe. This is EIRP, so measured radiated. 

You should be able to use 8 dBm here.
