Example WebSocket temperature humidity esp8266 compiling error

[VeloTobi]

Dear all,

I would like to try out the simple web server for D1 mini esp8266 (unfortunately, also other boards didn’t work…).

If I compile the code,

WebSocket-Esp8266-ESP32-Tutorial/03-Secure WebSocket with autentication on DHT temp hum/esp8266_TempHumidityWebServerWithWebSocket/esp8266_TempHumidityWebServerWithWebSocket.ino

at this link esp8266_TempHumidityWebServerWithWebSocket.ino

 the following message appears:

Can you help me? What do I have to change?

Thanks in advance,

Hi VeloTobi,

please check the core and library version, I test the sketch width these and It’s work

• Using board d1_mini
• Using core esp8266 2.7.4
• [ESP8266WiFi@1.0]
• [ESP8266WebServer@1.0]
• [WebSockets@2.1.4]
• [WebSockets@2.1.4]
• [Hash@1.0]
• [DHT12_sensor_library@0.9.0]
• [Wire@1.0]
• [ArduinoJson@6.13.0]

Bye Renzo

OK, thanks, I had another ArduinoJSON version and DHT12 instead of DHT12_sensor_library 0.9.0. I had to uninstall dht12 and replace with your library. BTW, also DHT12_sensor_library 1.0.1 seems to compile.

regards

Hi VeloTobi,

I also update the github project, now there is the simple version and the more complex.
