# Copy of espota.py from ESP32 Arduino project with some modifications.
|
|
#
|
|
# Original espota.py by Ivan Grokhotkov:
|
|
# https://gist.github.com/igrr/d35ab8446922179dc58c
|
|
#
|
|
# Modified since 2015-09-18 from Pascal Gollor (https://github.com/pgollor)
|
|
# Modified since 2015-11-09 from Hristo Gochkov (https://github.com/me-no-dev)
|
|
# Modified since 2016-01-03 from Matthew O'Gorman (https://githumb.com/mogorman)
|
|
#
|
|
# This script will push an OTA update to the ESP
|
|
# use it like: python espota.py -i <ESP_IP_address> -I <Host_IP_address> -p <ESP_port> -P
|
|
# <Host_port> [-a password] -f <sketch.bin>
|
|
# Or to upload SPIFFS image:
|
|
# python espota.py -i <ESP_IP_address> -I <Host_IP_address> -p <ESP_port> -P <HOST_port> [-a
|
|
# password] -s -f <spiffs.bin>
|
|
#
|
|
# Changes
|
|
# 2018-03-29:
|
|
# - Clean up Code
|
|
# - Merge from esptool for ESP8266
|
|
# 2015-09-18:
|
|
# - Add option parser.
|
|
# - Add logging
|
|
# - Send command to controller to differ between flashing and transmitting SPIFFS image.
|
|
#
|
|
# Changes
|
|
# 2015-11-09:
|
|
# - Added digest authentication
|
|
# - Enhanced error tracking and reporting
|
|
#
|
|
# Changes
|
|
# 2016-01-03:
