Hello everybody. I’m trying to learn Arduino environment and I started it with a Cactus Micro Rev2. Cutting parts from codes found on internet, I have this code:  
#include \< espduino.h \>

#define PIN\_ENABLE\_ESP 13  
#define SSID “**"  
 #define PASS "**”

ESP esp(&Serial1, PIN\_ENABLE\_ESP);

void setup() {  
Serial1.begin(19200);  
esp.enable();  
delay(500);  
esp.reset();  
delay(500);  
while(!esp.ready());  
esp.wifiConnect(SSID, PASS);  
}

void loop() {  
}

I have now some question I can’t answer:

- Is it the shortest code possible to get a wifi connection?
- How can I set a static IP?
- Which are the esp. commands available?
- Can anybody give me the right code to send an email (probably with ifttt), please?

I think it’s the shortest code for connecting wifi. Please check [our wiki](http://wiki.aprbrother.com/wiki/Cactus_Micro_Starter_Guide) first.

I already did it but perhaps my knowledge is too low to understand it. I didn’t find any help there.  
Do you mean I have to upload the firmware for “AT commands”?  
I’m sorry but I find your wiki chaotic and messy and I can’t find any help there.
