Hello guys,
I am using a Esp8266 Nodemcu for my project.My problem,when I scanning wifi device on my computer,I don’t see my Esp blynk .
My esp is working and I can send my code to my device.I can communicate with Uart my Arduino Uno but I dont see my blynk name on wifi map .How can I solve this problem?
• Add your sketch code. 
Code should be formatted as example below.
Simply paste your code between ``` If you don’t format your code, your topic can be deleted by moderators.
