Hello, just connecting my arduino+esp8266 to blynk but i have some problem.
This is what I have in the serial monitor.

It seems it freeze…
I changed the baud rate of esp8266 at 9600.
I opened the port 8442 in my router but my device is OFFLINE (in my router I have different ip associated at the esp mac address: 192.168.1.144 instead of 192.168.1.104 that i can see in the serial monitor).
What could be the problem?
It seems OK… so are you saying your App still shows device as disconnected?
As long as your phone and MCU are both within the same network (your home WiFi) then ports are not an issue. And both have internet access to the Blynk Cloud Server, then IP addresses are probably assigned via DHCP in your router and also fine… unless you are forcing static IP somehow in the ESP or on the router?
Reconfirm the authcode is the same in both App and sketch… refresh & email it again in the App, and then reenter it in the sketch.
thank you very much.
I don’t know why, today it works perfectly.
I never changed sketch or authcode. I can only think that my device was far from access point and its signal was low: but I was able to see it in my router page.
Now in the serial monitor i can see the time of the ping and all is ok.
I hope to know the reason of this problem to help someone. I will write if it will happen again.
If it works on one form of internet connection but not on another, then the issue is related to your method of internet connection, probably NOT Blynk related.
