External antenna switch?
-
Can i use P12 (antenna switch) on the Fipy? What does it do anyway?

This pin is connected to a RF switch that switches the WiFi/BT RF between the on-board ceramic antenna and the U.FL connector. If you are not using WiFi or BT you are free to use this pin, but be sure to disable the WiFi access point the device creates at boot with
import pycom pycom.wifi_on_boot(False) -
So if im using wifi/bl then i cannot use this pin? What if i'm using the ufl only?

This pin is directly connected to the WiFi/BT RF antenna switch so any signal you input or output may cause it to switch between the internal and external antenna setting.This effectively means you can’t use it if you use WiFi or BT.
