Sir, How can i pair blynk.begin with wifimanager?
Please give some examples for me to understand easily.
Sir,Instead of showing me nodemcu in the 𝐁𝐎𝐋𝐃 text next to blynk version, it is showing me ESP8266. Will it cause trouble?
What board type do you choose in the IDE when you compile the code?
Pete.
Sir, im using nodemcu.
Can you please check the last coding i sent?
Thank you.
Which NodeMCU type do you choose in the IDE?
Pete.
I selected type nodemcu 1.0 that only supports. Others didnt support as far as i can tell.
Thank you.
What ESP8266 Core version are you using?
Pete.
 use the Windows Sniping Tool or the newer Snip and Sketch tool to capture the relevant portion of the screen, rather than taking a photograph of your monitor.
Pete.
Bro listen carefully, you create complex code for simple task.
You don’t need to do anything with these functions if you want permanent mcu.
- serial print
- Wifi managing
- blynk managing
if you want correction in code contact me, I have 2 mcu those work seamless over 2 week.
If you really want modification in code stop using Arduino ide use platformio
Ok bro i will try it. the help of everyone is needed.
Hi bro
my device after 3 mounth again and again getting to offline plz help me and relace my coding.

please any one help me:cry:
digitalWrite command needs to use in place of pinMode. Start by searching mistakes in the code, and also do not use D3 as may cause problems. Google for usable pins on ESP8266. Choose a pin which is stable.
You’re also creating a SoftwareSerial port using GPIOs 10 and 11
GPIO 10 is a pin that should be avoided where possible (along with GPIO 9), and GPIO 11 is a reserved pin that is not broken out on the ESP8266 chip.
In addition, this SoftwateSerial port called ‘sim’ is never used, as it doesn’t have a serial begin statement and doesn’t appear anywhere in your sketch, so this line of code should be removed, along with this one:
Also, I’d encourage you to place all of your variable declaration statements and #defines together near the top of your sketch, so that you can easily spot any conflicts, rather than having them scattered about your code.
Also, this line is included twice…
Also, you need to have a way to limit your notifications to no more than once every 5 seconds.
If all has been working well for 3 months and you’ve not re-flashed your NodeMCU with fresh code then you should start looking at other issues, such as your WiFi router or ISP.
Pete.
