Hi I am using Arduino uno & ESP-01
ESP-01 is working well when I put firmware to ESP, for example, wifi spreading or AT command is okay.
but when I disconnect arduino from PC(disconnect USB connection)
ESP-01 suddenly do not work anything. no spread wifi, no AT command reaction..
so I always have to re-input the firmware to ESP again, for make it work again.
How can I make maintain ESP-01 's firmware?
picture is my connection status. thank you
