## Library SIM800l Module for Arduino UNO The Purpose of This library is to use the module in the most easy way and transparent. Website: [Sim800l library](https://cristiansteib.github.io/Sim800l) ## Download and Install. Go to [Releases](https://github.com/cristiansteib/Sim800l/releases) click the " Source Code (zip) " button, then rename the uncompressed folder to **Sim800l**. Check that the *Sim800l* folder contains Sim800l.cpp and Sim800l.h Go to arduino IDE Sketch >> Import Library >> add library... Select the folder Sim800l OR Place the Sim800l library folder your arduinosketchfolder/libraries/ folder. You may need to create the libraries subfolder if its your first library. Restart the IDE. ## Connections & pinouts Arduino Uno | Sim800l | Notes -------------|-------------|------------ +5v| (3.8v)~(4.4v)!| Power supply input 10 RX_PIN | TX | 11 TX_PIN | RX | 2 RESET_PIN | RST| Reset Pin GND | GND | ## Methods and functions Name|Return|Notes :-------|:-------:|:-----------------------------------------------:| begin()|None|Initialize the library reset()|None|Reset the module,and wait to Sms Ready. sendSms(number,text)|true or false|parameters must be Strings. readSms(index)|String|index is the position of the sms in the prefered memory storage getNumberSms(index)|String|returns the number of the sms. delAllSms()|true or false|Delete all sms answerCall()|true or false| callNumber(number)|None| hangoffCall()|true or false| getCallStatus()|uint8_t|Return the call status, 0=ready,2=Unknown(),3=Ringing,4=Call in progress setPhoneFunctionality()|None|Set at to full functionality activateBearerProfile()|None| deactivateBearerProfile()|None| RTCtime(int *day,int *month, int *year,int *hour,int *minute, int *second)|None| Parameters must be reference ex: &day dateNet()|String|Return date time GSM updateRtc(utc)|true or false|Return if the rtc was update with date time GSM. ____________________________________________________________________________________ You can regulate the voltage to the desired with this, is not the best, but for start it's easy.  For the **reset pin** they need NPN transistor, this is an example circuit that you can use.
