About

Use an esp32-camera supported device to "snap" pictures and publish them via MQTT.

The ESP32-CAM enabled device will subscribe to a configured MQTT topic and wait for the "snap" command, this command will trigger an action to capture and send an image over MQTT to a configured topic (might be a different topic to the one used for the "snap" command).

A concrete example may be to use an ESP32-CAM device to communicate with a user created Telegram bot, then take snapshots and share them from a Telegram account.

Build the project

The project needs to be configured before building it for the first time. Run the "menuconfig" of the project and configure all the items listed under the esp32cam_snap menu

idf.py menuconfig

Once the project is configured, it should be possible run build, flash and monitor it:

idf.py build
idf.py flash monitor

To exit the monitor use Ctrl + ].

Build the component documentation

To generate the component documentation, Doxygen needs to be locally installed. The documentation can be generated with the following command:

cd doc/component/documentation
doxygen

The documentation in HTML format is stored in the html folder.
