nRF21540 runtime SPI+GPIO gain controlhttps://devzone.nordicsemi.com/f/nordic-q-a/105449/nrf21540-runtime-spi-gpio-gain-controlHi, I can set TX gain on build time and it is clear how to do here working with fem. But I wanted to control the runtime TX gain of nRF21540 using nRF21540DK, nRF Connect SDK 2.5.0, BLE mesh chat example.
