The Purpose of This library is to use the SIM800 module providing core functionalities while still maintaining strong performance and being memory efficient.
If you like BareBoneSim800 - give it a star, or fork it and contribute!
This Library uses the AltSoftSerial Library instead of the SoftSerial Library to allow for compatibility with other PinChange Interrupts Library and SPI Libraries
- Send SMS, Read SMS and Delete SMS
- AT Command Test
- Send and Receive HTTP data
- TCP Connection
- IoT Applications
- Low power saving mode
- Location and Time Update
Please kindly follow the examples in the example folder.
Go to Release and click the " Source Code (zip) " button to download the latest release, then rename the uncompressed folder to BareBoneSim800. Check that the BareBoneSim800 folder contains BareBoneSim800.cpp and BareBoneSim800.h and copy the folder into the Arduino Library directory in your documents folder. i.e Place the BareBoneSim800 library folder your arduinosketchfolder/libraries/ folder. You may need to create the libraries subfolder if its your first library. Restart the IDE and you are good to go.
Go to arduino IDE Sketch >> Import Library >> add library... Select the folder BareBoneSim800

| ARDUINO UNO >>> SIM800L |
-----------------------------
GND >>> GND
RX 8 >>> TX
TX 9 >>> RX

You can regulate the voltage to the desired voltage by using a diode to step down th Arduino 5V to 4.2v or just use a Lipo battery

Thank you for downloading and enjoying the BareBoneSim800 library. I hope you find it useful. Heck, I wrote it for you- yeah, that's right- you.
This Library was inspired from the SIM800 Library from Cristainsteib(https://cristiansteib.github.io/Sim800l) and the Powerful TingGSMLibrary by Volodymyr Shymanskyy. Special Thanks to Paul Stoffregen that created the AltSoftSerial (http://www.pjrc.com/teensy/td_libs_AltSoftSerial.html) Library, it's library was the backbone of this Library communication
