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:

Code: Select allCommunication with MCU established.
Can't autodetect firmware, because proper answer not received (may be unknown firmware).
Please, reset module or continue.
2013,rst cause:2, boot mode:(3,6)

load 0x40100000, len 29824, room 16
tail 0
chksum 0x0b
load 0x3ffe8000, len 3064, room 8
tail 0
chksum 0xc3
load 0x3ffe8bf8, len 8, room 8
tail 0
chksum 0xa5
csum 0xa5

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

- Mon Jun 13, 2016 7:33 am #49112 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.

- Mon Jun 13, 2016 1:09 pm #49134 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.
