Virtuino IoT - Web Socket connection with ESP8266 part2

[@JAQ1921]

Why can't I connect to the application using the access point (ESP32) to read the temperature from the DS18B20 sensor (OneWire and DallasTemperature library)? When I enter the IP address in the application, there is no connection, but when I remove the code responsible for the DS118b20 sensor, I connect to the application.

Hello, the phone has to be connected to the esp access point network form the wifi settings.

@@iliaslamprou Hi, the phone is connected to the ESP network

@@JAQ1921 I am sorry for the previous answer. I have no idea about this issue. I need more information and some screenshots. Please ask this question to Virtuino forum

Does the connection only happen if my Virtuino IoT app phone and ESP8266 are on the same LAN? Because if I am outside the local network and connected to the operator's network, the connection does not occur.

Hello, you can controll the ESP8266 outside of the LAN using the data connection. You have to "portforward" the internal IP and port in your router settings. Check your router settings for this.
This documentation will help you:
virtuino.com/index.php/virtuino/documentation/virtuino-ip-settings-for-internet-connection
but you can find unlimited tutorials on youtube.
On Esp8266 code you don't need to do nothing.
On Virtuino project you have to change the internal IP with the external ip and port
On your router settings you have to make the port forwarding.
This is the reason Virtuino IoT supports two IPs. You can add both ips (internal and extrernal).

I have 1 Virtuino IOT application, when ESP8266 and smartphone are connected to 1 wifi, they can control each other. When the smartphone switches to 4G and the ESP8266 uses wifi, they cannot control each other. Please help me! Thank you!

@@iliaslamprou Hello sir! Thank you for your guidance. I tried to install it but it still doesn't work.😄

​@@ThanhNguyen-yj4vn Hello, I think you have to use a Port Forward tester to be sure that the port is open and the communication is allowed. www.yougetsignal.com/tools/open-ports/

@@iliaslamprou hello sir! Thanks for the guide. i tried it but no port is open.

@@ThanhNguyen-yj4vn I can't help you with this. You have to check the router settings. First of all you have to disable the firewall.
