### 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 13,802 bytes (44%) of program storage space. Maximum is 30,720 bytes.
|
|
Global variables use 661 bytes (32%) of dynamic memory. Maximum is 2,048 bytes.
|
|
```
|
|
Now, you have more space for your experiments.
|
|
TinyGSM also pulls data gently from the modem (whenever possible), so it can operate on very little RAM.
|
|
|
|
### Supported modem models
|
|
- [x] SIMCom SIM800 series (SIM800A, SIM800C, SIM800L, SIM800H, SIM808, SIM868)
|
|
- [x] SIMCom SIM900 series (SIM900A, SIM900D, SIM908, SIM968)
|
|
- [x] Neoway M590
|
|
- [x] ESP8266 (AT commands interface, similar to GSM modems)
|
|
|
|
### Supported modules
|
|
- [x] GPRSbee
|
|
- [x] Microduino GSM
|
|
- [x] Adafruit FONA (Mini Cellular GSM Breakout)
|
|
- [x] Adafruit FONA 800/808 Shield
|
|
|
|
More modems may be supported later:
|
|
- [ ] AI-Thinker A6, A6C, A7
|
|
- [ ] Quectel M10, M95, UG95
|
|
- [ ] SIMCom SIM5320, SIM5216
|
|
- [ ] Telit GL865
|
|
- [ ] ZTE MG2639
|

Watch this repo for new updates! And of course, contributions are welcome ;)
|
|
|
|
## 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 and specific voltage 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
|
|
|
|
### SoftwareSerial problems
|
|
|
|
When using ```SoftwareSerial``` (on Uno, Nano, etc), the speed **115200** may not work.
|
|
Try selecting **57600**, **38400**, or even lower - the one that works best for you.
|
|
Be sure to set correct TX/RX pins in the sketch.
|
|
|
|
### Diagnostics sketch
|
|
|
|
Use this sketch to diagnose your SIM card and GPRS connection:
|
|
File -> Examples -> TynyGSM -> tools -> [Diagnostics](https://github.com/vshymanskyy/TinyGSM/blob/master/tools/Diagnostics/Diagnostics.ino)
|
|
|
|
### Broken initial configuration
|
|
|
|
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)
