No, it was not airplane mode. I want to explain one more time in brief.Yes, I assumed that it does from the "Airplane Mode" icon in the picture he posted.
where I have misunderstood.well you are experienced in esp8266, so can you elaborate me what should I do? I expect you will provide me right path.Clearly you have misunderstood what was said. I have been designing with the ESP8266 for several years now on a number of products and understand its capabilities.
Good luck.
