Yes, that is what I wanted. Thank you.

Considering how big the pdf on commands is the one on examples is rather disappointing. I have found an example or two elsewhere. I have a feeling one can do a lot more with just the AT commands that is apparent from the examples they present in the pdf.

For example this looks interesting:

First of all, thanks for the excelent book, it helps a lot.

I'm doing a IoT project and I'm using the ESP12 to send data from a sensor to a database. I use the Arduino IDE to program the ESP12. Normally, the code works good, what sometimes, the ESP12 do the famous "resets" that everybody talks. I have done all the tips that I heard:

- Put capacitors beetween Vcc and GND in a good PCB (I'm electronic technician and I know about this)
- Put delay() and yield() function inside the Arduino code.
- Update news firmwares like NodeMCU (I haven't tried to update the official firmware from espressif yet)

But, even with all of this, the ESP12 still do this resets with the same errors printed through de UART port: Escpetion(0), Excpetion (9) or Exception (29). The worse thing of this resets is that sometimes the ESP12 doesn't restart the code and keeps locked doing anything. And another bad thing is that sometimes delets all the EEPROM that I used in the code to store some data inside.
I've noticed that this kind of errors happens after update a new code with the Arduino IDE. If the code stars good and nothing wrong happens at the beginning, the ESP12 goes good for several hours. But after some hours, it do this horrible resets.

I don't know what more I can do, I'm starting to think that the ESP8266 is not stable enough for IoT aplications. I hope that with your experience with the ESP8266 could help me to find a definitive solution with this resets.

Thanks a lot
