@hrish-kumar The documentation is clear about it, e.g. for WiPy3: https://docs.pycom.io/datasheets/development/wipy3/
The 3.3vV Pin is OUTPUT ONLY. The external antenna can be selected using the wlan.antenna() method. See here: https://docs.pycom.io/tutorials/networks/wlan/#using-an-external-antenna

So never forget to look into the documentation first. it's made for that
