- Tue Jun 06, 2017 5:29 pm #66836 What firmware (and version) are you using?
At least the AT+GMR command should work, since it returns the version of the firmware installed.

If things are not working as expected, you can try an older version (v2.3) of the ESP Flash Download Tool, to see if that works better.
Maybe you've got better luck using the older how-to on All About Circuits (so using PuTTY instead of Termite).
Also use one of the latest firmware versions, to make sure you've got a stable one.
It's important to make sure that the power is a solid 3.3V when flashing and that you select the correct flash-size in the flasher tool.

Assumption is the mother of all f*ckups. At least: that's what I'm assuming.
