- Thu Aug 04, 2016 10:36 am #52122 Hey there, I tried out the current version of ESP-lorer, with NodeMCU v. 0.9, but didn't really find the getting-started-guide helpful, didn't work for me the way described there.

Flashing seemed to work, although the device is not usable, I added my user to the 'tty'-group, not having any fun with this item yet, not workable.

So this clearly is not workable yet, am I supposed to use ESPlorer as root, or did I select to may modules, flashed in a wrong way??
The LED looks different already than it did, when the device was new, had been flashing once only on connect, now it's kind of flickering.
Not getting any screen on /dev/ttyUSB0 either, so is the hardware defective, or what's the matter ??
