I want to connect ESP to Arduino Nano, to send information via wifi fom arduino sensors. I want to use AT commands.
I've flashed the firmware - ESP8266_NONOS_SDK_V2.0.0_16_08_10. I have connected VCC and CH_PD to external 3.3V power supply, GND and GPIO15 -> GND, Tx -> Tx, Rx -> Rx with voltage divider to drop 5V -> ~3.3V.
I've plugged Arduino (with reset and ground connected) to computer and opened serial monitor. ESP gives me a message at baud 74880:

but it doesn't respond to any AT commands. Any help is appreciated
