I am working with nodemcu for a relay control. And i am using Blynk local server on my RPi3 , and the server up and running fine, even am able to access it on my Blynk app. The problem here is with 3 main things
- Arduino IDE (versions)
- Blynk server
I tried different versions of Arduino ide but some shows some unknown characters in the serial monitor(tried play with baud rate as well). In some version 1.6.12 i got the serial monitor running fine and it shows the nodemcu is connected to the given ssid and trying to connect to the specified ip address of local server but never connects. I have made sure the id address is the same in both code and router page. (connecting to xxx.xxx.x.x:80) this goes on forever and ever.
But with the same local server, few days back everything was working good. But now uploading the same code as before (nothing changed, even the hardware. (also got new nodemcu & facing the same issue) ), is still not working.
And if anyone has tried using the latest version of Arduino ide trying installing the boards of esp8266 and install the latest version available in the boards manager. we get couple of more options while nodemcu board selected.(flash- sketch only , wifi settings , sketch+wifi setting) and much more. with this we cant even upload the sketch and serial monitor will be blank.
i went through the posts in the Blynk forum but did not find anyone experiencing this sought of problem.
Please help me out.
