# 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>
