I successfully installed iGate Firmware 4.0.4 on a T-Beam 1W using the Webflasher. Everything works like a charm, and the new UI looks amazing!
However, while configuring the LoRa settings, I noticed I couldn't set the TX power to 30 dBm; the interface limits the maximum value to 22 dBm.
Is this limitation intentional, or is it a minor bug?

hi , the Tbeam 1W has a maximum value it can stand before damaging it.

besides , it has a LNA that pushes from 22 to 30dBm internally
