Newbie here. I recently purchased 3 ESP-201 modules from eBay. My goal is to eventually use the Arduino IDE to program the ESP module, however in the mean time, I want to interface an Arduino Pro Mini 3.3V and mess around with the AT command set. In order to do this, I need to lower the baud rate so that it will work with the Arduino Software Serial library. I got one of the ESP modules running fine on serial with a FTDI FT232 3.3V module using RealTerm and my PC at 115200 baud. I then wanted to update my firmware to the latest from Esspresif in order to have a known AT command set that I could find documentation for. I followed the instructions in the following link http://www.allaboutcircuits.com/projects/update-the-firmware-in-your-esp8266-wi-fi-module/ using the latest from Esspresif (ESP8266_NONOS_SDK_V2.0.0_16_07_19) and ESPFlashDownloadTool_v3.3.4.exe I had an error during the flashing process and now my ESP module is unresponsive. I'm hoping there may be a way to resurrect this module, but I'm not sure what I did wrong, and how to go about fixing it. Any help would be appreciated.
