### 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.
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.

## Troubleshooting
When using ```Software Serial``` (on Uno, Nano, etc), the speed **115200** may not work.
Try selecting **57600**, **38400**, or even lower - the one that works best for you.
### SoftwareSerial problems

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