/**************************************************************************************************
|

*
|
||||
* Over The Air updates (OTA) - 02Aug23
|
||||
* MODIFIED FOR USE WITH ESP32CamDemo (no log, different header)
|
||||
*
|
||||
* part of the BasicWebserver sketch - https://github.com/alanesq/BasicWebserver
|
||||
*
|
||||
* If using an esp32cam module In Arduino IDE Select "ESP32 dev module" not "ESP32-cam" with PSRAM enabled
|
||||
*
|
||||
**************************************************************************************************
|
||||
|
||||
Make sure partition with OTA enabled is selected
|
||||
|
||||
To enable/disable OTA updates see setting at top of main sketch (#define ENABLE_OTA 1)
|
||||
|
||||
Then access with http://<esp ip address>/ota
