- Sat Jun 04, 2016 5:16 am #48552 Hello, I've been trying to set up my NodeMCU for the past couple of days, it shipped with a bad Reset and Flash button, so I've had to ground both the pins manually before flashing or connecting.

I followed the guide at http://www.foobarflies.io/a-simple-conn ... -and-mqtt/,

And apparently the firmware has been installed successfully, because I got the following result in the command prompt

C:\Python27\Scripts>python esptool.py -p COM5 --baud 115200 write_flash -fm dio -fs 32m 0x00000 nodemcu-master-15-modules-2016-06-04-09-36-11-integer.bin

esptool.py v1.1
Connecting...
Running Cesanta flasher stub...
Flash params set to 0x0240
Writing 466944 @ 0x0... 466944 (100 %)
Wrote 466944 bytes at 0x0 in 40.5 seconds (92.3 kbit/s)...
Leaving...

However, when I run the PuTTY terminal, it doesn't connect at all, and on running ESPlorer, the output I get is

PORT OPEN 115200

and this goes on indefinitely.

Any help will be greatly appreciated, Thanks!!
