Well, first: How to set the tx power to more than 12 dBm on 433 MHz - #7 by SR7673
And then: Remote Node Administration does not work, somehow - #31 by SR7673
So, i DID measure 20 dBm today… …but just with the RAK4631 under V2.0.13. However not on the T-Beam, even with 2.0.13. What’s why i started that thread.
