## Features

#### Supports Arduino Client interface
This library is very easy to integrate with lots of sketches, which used Ethernet or WiFi previously.  
Examples for **Blynk**, **MQTT**, **Web Client** and **File Download** are provided.  
![examples](/extras/examples.png)

#### Tiny
WebClient example for Arduino Nano (with Software Serial) takes little resources:
```
Sketch uses 11,916 bytes (38%) of program storage space. Maximum is 30,720 bytes.
Global variables use 649 bytes (31%) of dynamic memory. Maximum is 2,048 bytes.
```
Now, you have more space for your experiments.

#### Supported modules:  
SIM800, SIM800A, SIM800C, SIM800L, SIM800H, SIM808, SIM868,  
SIM900, SIM900A, SIM900D, SIM908, SIM968  
More modules (SIM5320, SIM5216, A6, A6C, A7, M590, MG2639) may be supported later. Contributions are welcome!

#### Uses internal modem buffer for receive
TinyGSM pulls data gently from the modem, so it can operate on very little RAM.

## Getting started

  1. Using your phone:
    - Disable PIN code on the SIM card
    - Check your ballance
    - Check that APN,User,Pass are correct and you have internet
  2. Ensure the SIM card is correctly inserted into the module
  3. Provide a good, [stable power supply](wiki/Powering-GSM-module) (up to 2A, 4.0-4.2V or 5V according to your module documentation)
  4. Check if serial connection is working (Hardware Serial is recommended)  
     Send an ```AT``` command using [this sketch](tools/AT_Debug/AT_Debug.ino)
  5. Check if GSM antenna is attached

## Troubleshooting

Sometimes (especially if you played with AT comands), your module configuration may become invalid.  
This may result in problems such as:

 * Can't connect to the GPRS network
 * Can't connect to the server
 * Sent/recieved data contains invalid bytes
 * etc.

To return module to **Factory Defaults**, use this sketch:  
  File -> Examples -> TynyGSM -> tools -> [FactoryReset](https://github.com/vshymanskyy/TinyGSM/blob/master/tools/FactoryReset/FactoryReset.ino)
