ESP8266 Community Forum

Hi,

I recently purchased 3 ESP8266-01 to learn how to use them and, following several online tutorials, I installed the latest firmware. However, all three devices respond the same way when using ESP-Explorer:



I used NODEMCU flasher and the latest bin file (nodemcu_integer_0.9.6-dev_20150704.bin). All three devices updated correctly (config used: Baudrate 115200 Flash size 4MB Flash Speed 40MHz SPI Mode DIO).

Having that said, I’m not sure where to go from here since none of the 3 devices are responding to the AT test.

Any help is appreciated.
TIA

NodeMCU is one firmware and AT firmware is another. Uploading the first one overwrite the previous, you can not have both at the same time. NodeMCU firmware doesn't respond to any AT commands.

I see. Somewhere in the tutorials I missed that information. So which latest firmware should I use for the Arduino’s IDE? For something like console.println(“Hello word”)?
Thank you.

each compiled sketch from Arduino ide is complete firmware for esp.
any previous firmware inside esp will be overwrited with Your new sketch from Arduino.
