I have an ESP 01 module which I plan to use with Arduino nano, but it doesn't respond to AT commands even after I reflashed it with AT Firmware v0.9.2.2. And also, the blue led on the board only flashes when the ESP 01 is connected to power source. Any help?
I tried sending AT commands with the BareMinimum code. I also used the code from this to no avail. Tried to connect both TX to TX and TX to RX, used the voltage divider on the RX pin and connected the GPI0 to ground while uploading the sketch, but still no response.
