#ESP32 - LED button update
2+
3+
This is an example of how one can update inline keyboard messages (buttons).
4+
The message_id of the specific message is sent when a message is received.
5+
This message_id can be used to UPDATE that message.
6+
One can update text inside a message, but also buttons can be updated.
7+
This way one can build menu's, like the menu the botfather uses.
8+
9+
In this simple example we use a inlinekeyboard button to toggle (and update) the state of a LED.
10+
11+
NOTE: You will need to enter your SSID, password and bot Token for the example to work.
12+
