See/change tx power

Hello everybody.

I just tried the CubeCell LoraWAN OLED Example on TTNv3. Used OTAA, ADR OFF, EU868 and UNCONFIRMED.
I’m unsure how much tx power is used sending frames. I’ve read already, that with ADR ON, the tx power is adjusted automatically. But I need ADR OFF.

So my questions are:

  1. How can I read out the used tx power for joining/transmitting uplink messages?
  2. How can I set/enforce the used tx Power for joining/sending?

Thank you very much.

Kind regards
