Wifi module broken ?!

Need Help With My Project

It just suddenly stoped working… I connected it to my PC to look at the Serial output:

[29] Blynk v0.3.1

I used it to run a relay (I know how to connect it (Diode etc.)) and some sensors. I think something was wrong with the power connection (the ESP8266 got really hot (I used a logic converter and 3.3V)

Hardware: Arduino Nano, ESP8266 WiFi module, HTU21D Humidity Sensor (Sparkfun)

And here is the code:

 * This example shows how to use ESP8266 Shield via Hardware Serial
 * (on Mega, Leonardo, Micro...) to connect your project to Blynk.
 *
 * Note: Ensure a stable serial connection to ESP8266!
 *       Firmware version 1.0.0 (AT v0.22) or later is needed.
 *       You can change ESP baud rate. Connect to AT console and call:
 *           AT+UART_DEF=115200,8,1,0,0
 *
 * Change WiFi ssid, pass, and Blynk auth token to run :)
 * Feel free to apply it to any other example. It's simple!

*update

I get this here from the Serial Monitor:

but I can’t send any commands :confused:

The module is broken, but I had another one (that WAS broken) I needed to flash the Firmware, now it Works fine :smiley:
