# Allows PlatformIO to upload directly to AsyncElegantOTA
#
# To use:
# - copy this script into the same folder as your platformio.ini
# - set the following for your project in platformio.ini:
#
# extra_scripts = platformio_upload.py
# upload_protocol = custom
# upload_url = <your upload URL>
# 
# An example of an upload URL:
# upload_URL = http://192.168.1.123/update
