You should install the ESP Async TCP library by ESP32Async, also available in the Arduino library Manager. Unninstall any other ESP Async TCP libraries you may have.

Hi Sara,
good question probably. I have installed :
ESP Async WebServer by ESP32Async Version 3.7.10
ESP AsyncTCP by dvarrel Version 1.2.4
and I found ESPAsyncWebServer by lacamera Version 3.1.0. I think I didn’t install this third one but it is listed in the “Installed libraries”.
It seems they are the right ones, according to the tuto, but I don’t know how comes the third one. Could it be an issue ?
Many thanks
Philippe

Hi.
What libraries for the ESPAsyncwebserver are you using and which versions?

Hello, I have tried a lot of your scripts and am very satisfied of them.
I am trying to run the ESP8266 WebServer for BME680and I get a strange error and cannot understand what to do.
Error is : no matching function for call to ‘AsyncWebServerRequest::send(int, const char [10], const char [2996], String (&)(const String&))’
and the concerned lines are (186, 188):
// Handle Web Server
server.on(“/”, HTTP_GET, [](AsyncWebServerRequest *request){
request->send(200, “text/html”, index_html, processor);
Can you tell me what this means and what I have to change ?
Many thanks.

Hi.
Reset your board after opening the serial monitor so that you can catch the IP address before it runs the rest of the code.

I used this program until I changed my ISP provider. I, also, upgraded the Arduino IDE to version 2.3.2. I am still using a Wemos D1 mini.
My current problem is the serial monitor does not give me an IP address for the device. It immediately starts to display the starting station message.
Does the newer IDE cause this? Originally I used version 1.8.x.

Thanks

Has anybody tried running this using a battery with an esp8266 or ESP32? I’ve tried running both with ‘Deep Sleep’ functions and getting a day’s use from a 3.7v 1600mah battery, I get marginally better with an ‘Unexpected Maker FeatherS3’ (not a lot out there for the board at the moment) that turns the I2c off in deep sleep mode.
Any help would be greatfull!

Hi.
What is exactly the error that you get?
After opening the IP address on the web browser, open the JavaScript console and check if you get any errors.
