Thank you for your reply.
I actually had expected the ESP32-Arduino API to have more such features meanwhile, tbh...

thank you, but I do not understand. 1st, there are no demo pictures and no explanations in your link, 2nd, I need Arduino IDE/API for it, no IDF, and 3rd, I cannot see how this linked lib would work with exactly which BT HID keyboard types (all types? e.g. this one? https://www.amazon.de/Rii-Bluetoo...

no ideas?
or HID keyboards not possible?

what means BLE?
now which one can detect and connect to a BT HID keyboard and then read input?
which BT (or whatever) keyboards are supported?
Where can keyboard ino examples be found for Arduino IDE?

is there a ESP32 version which can connect to a BT HID keyboard and then read user input via stdin (e.g., scanf(), gets(), std::cin ) ?

hello, the ESP32 could host a website like for your SimpleWiFiServer LED on/off example, plus show an arbitrary anolog value or even a graph/chart for it like in your AdvancedWebServer example. Then additionally the ESP32 could act as a WebServer to connect to any other ESP Clients. It might send me...

hello, I'm quite new to ESP32 Arduino... Now I'm looking for example to connect a 2nd esp as a client to ESP32 Server. Given: ESP32 Webserver generating a website via html, e.g. to switch an LED ON/OFF. Now I want to connect to a 2nd ESP which is sending values (e.g. of a DHT22 temperature sensor), ...

now they are visible, thank you!

my 3 topics/posts have vanished - where have they gone?

you may also use UART RX/TX between both ESPs, but not wired by cables but with 2 paired HC05 modules in between for WL transmission, using just the standard Serial communication though.
