A small Arduino library for GSM modules, that just works.

### Arduino Client interface support
This library is easy to integrate with lots of sketches, which use Ethernet or WiFi.  
Examples for **PubSubClient ([MQTT](http://mqtt.org/))**, **[Blynk](http://blynk.cc)**, **Web Client** and **File Download** are provided.

### TinyGSM is 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
- [x] SIMCom SIM800, SIM800A, SIM800C, SIM800L, SIM800H, SIM808, SIM868
- [x] SIMCom SIM900, SIM900A, SIM900D, SIM908, SIM968

More modules may be supported later:
- [ ] SIMCom SIM5320, SIM5216
- [ ] AI-Thinker A6, A6C, A7
- [ ] Quectel M10, M95, UG95
- [ ] Neoway M590
- [ ] ZTE MG2639

Watch this repo for new updates! And of course, contributions are welcome ;)

### Uses internal modem buffer for receive
TinyGSM pulls data gently from the modem (whenever possible), 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](https://github.com/vshymanskyy/TinyGSM/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)
