Hello, I use Arduino-uno board & ESP 01 from Ai cloud inside
My little Esp is working well when I upload its firmware, for example, send&receive AT command, wifi connect, check its status by Arduino serial...
but the problem is, when I disconnect my arduino from PC( usb connection),
Esp's function is not working on. It do not react AT command, do not spread wifi signal..
so everytime detaching ESP from PC and re connect,
I have to re-download the firmware to ESP again for make it right.
can you give me some help about this problem????
my connection status is on the picture. (in the 2nd picture, tx & rx is different from manual because of using software serial)
