I just got the ESP-12N board on Amazon with NodeMCU on it! I plugged it in to my Win7 64bit laptop USB port and got the following from ESPlorer (which I just unzipped and ran):

------------------------------------------------------------------
PORT OPEN 9600

Communication with MCU..Got answer! Communication with MCU established.
AutoDetect firmware...

Can't autodetect firmware, because proper answer not received (may be unknown firmware).
Please, reset module or continue.

BTW, this is what the cmd.exe window launched by ESPlorer says:

Then I went to the ESPLorer pane with the "Scan Network" button and "Connect to AP" under the "Commands" tab and clicked on them and got:

"Scan Network" button
--------------------------------
> import network;nic = network.WLAN(network.STA_IF);nic.scan()
stdin:1: '=' expected near 'network'
>
--------------------------------

"Connect to AP" button
------------------------------------
> import network;nic=network.WLAN(network.STA_IF);nic.active(True);nic.connect('MySSID','password')
stdin:1: '=' expected near 'network'


What am I doing wrong?

Thanks!

- Thu Apr 26, 2018 8:58 am #75610 You are not doing anything wrong. For some reason, the code snippet that ESPlorer uses for the "Scan Network" function is written in MicroPython, not LUA.

Code: Select allimport network;
nic = network.WLAN(network.STA_IF);
nic.scan()
