      Hi there,

      I'm trying to figure out how to work with the external antenna. There's the RF switch which can be triggered with a WiFi(antenna=WLAN.EXT_ANT) but I'm trying to figure out what is happening since I switch back and forth between the Pycom firmware and ESP32 IDF firmware running C/C++.

      Looking at the reference design I cannot quite figure out which pin is set to high/low to activate the switch. Looking at a Pighixxx scematic it should be the GPIO16 on the chip.

      Could someone shed some light?

      Thanks,
      Martijn
