Setting tx/rx power to antenna (external socket especially)

[kemalihsan]

Hello Folks,
Anybody knows whether one can adjust the tx power to the antenna (especially to an external antenna) in ESP32 kits?
I am looking for source code examples or if there is any way to do it on the hardware level
thanks...

The value in menuconfig is 20. And the docs say the default setting in the SDK is level0 (max tx power). So them are by default configured for max transmission power, right?

Is there any possibility that max tx power could result in more dropped packets than less power? Why would anyone config the ESP32 to anything other than the default?

If they were using an external amplifier or high gain antenna and don't want to violate the law.
