pip install blynk-library-python

For Blynk.Edgent Dynamic provisioning, please see examples/Edgent_Linux_RPi

ESP32/ESP8266 installation

Get the latest MicroPython firmware and flash it to your board
Note: for ESP32 you can also try LoBo firmware
Edit ESP8266_ESP32.py example (put your auth token and wifi credentials)
Use ampy or any other method to transfer files to the device
```
export AMPY_PORT=/dev/ttyUSB0
ampy mkdir /lib
ampy put BlynkLib.py /lib/BlynkLib.py
ampy put ./examples/hardware/ESP8266_ESP32.py main.py
```
Note: LoBo firmware stores files uder /flash directory, use ampy mkdir /flash/lib and so on
Open device terminal and reboot the board (or type execfile('main.py'))
For ESP8266, you may need to disable secure connection using:
```
blynk = BlynkLib.Blynk('YourAuthToken', insecure=True)
```
