Well, This is a stupid question of course. CTR+[x] is not to handle as an ASCII character (as for normal data entry) but as a string of binary code. Typically CTRLC sends to the server a hexadecimal string of FFF4FFFD06. So I did manage to handle these specific strings with my telnet server interact...

Hi,

I have a Telnet server running that stops to work when a telnet client sends a CTRL C character.
Is it a way to catch this break character from the client.

The script is in C++ compiled with ARDUINO IDE
Thanks in advance

Hello, I hope this is not a stupid question !!! Is it possible to use FFAT file system with an SD card rather with memory? I would like to use RRD tools as central database (on SD card) to collect and later graph sensor data. According to https://github.com/lbernstone/rrdtool_ESP32, FFAT is the only...

Is it Arduino which is responsible to port the ESP32 library to the Arduino IDE ?
I read in the library header:
Copyright 2015-2016 Espressif Systems (Shanghai) PTE LTD

It doesn't matter which platform to use, explanations of this issue using the ESP-IDF libraries is also OK for me.

Hi, I try to understand how the ESP32 SPI library manages concurrent SPI access on the same bus and more specifically when a transaction is initiated by an Interrupt. For interrupts, the Arduino SPI library manages that type of conflict using the SPI_HAS_TRANSACTION flag allowing the use usingInterr...

OK .... I understand it but after some tests despite the fact lack of documentation (with the exception of the one of Kolban)
Thanks

Hello,

I couldn't find in the ESP32 documentation any reference to Is this function obsolete or replaced by : Alternatively where can I found a description and of course the need to use various gpio_pad_xx() functions.

Thanks in advance

Hi, I am using the CameraWebServer example with an ESP32-CAM without problem, however I couldn't find a way to protect the server access with username and password. This sketch is using the esp_http_server.h library and after reading the https://docs.espressif.com/projects/esp-idf, I was unable to u...

Hello, Trying to build an surveillance camera with the esp32-cam module, I want to be able to detect if a HTTP connection the the ESP32 as WEB server is started yes or not. As basic sketch I am using the CameraWebServer.ino from the ESP-ARDUINO set. I must say that I have a big problem to understand...

Thank-you for your answer.
I don't plan to dig into the FreeRTOS code which e is above my capacities. However I think I understand the way I will be able to implement the semaphore technique that you have mentioned.
