# Optionally some environment variables can be set:
#
#   FQBN        Fully Qualified Board Name; if not set in the environment
#               it will be assigned a value in this makefile
#
#   SERIAL_DEV  Serial device to upload the sketch; if not set in the
#               environment it will be assigned:
#               /dev/ttyUSB0   if it exists, or
#               /dev/ttyACM0   if it exists, or
#               unknown
#
#   MDNS_NAME   Hostname of the Arduino; if not set in the environment
#               it will be assigned a value in this makefile. This is
#               needed for OTA update, the device will be searched
#               on the local subnet using this name
#
#   OTA_PORT    Port used by OTA update; if not set in the environment
#               it will be assigned the default value of 8266 in this
#               makefile
#
#   OTA_PASS    Password used for OTA update; if not set in the environment
#               it will be assigned the default value of an empty string
