Notes

• The board advertises itself as ‘wipy-wlan-xxxx’ or ‘sipy-wlan-xxxx’ or something similar where ‘xxxx’ are four hexadecimal digits. The password for all these networks is ‘www.pycom.io’:

  Default AP WiFi credentials.
  
  2 fipy-wlan-42bc (3, 'www.pycom.io') 0
  

• To compile before uploading and upload the compiled file (you need mpy-cross in your path):

  mpfs > putc boot.py
