About The Project

This library was created with intent to support Rust usage and prototpying on ESP32 boards with help of esp-rs project that enables use of Rust on various SoCs.

The project was mainly based on the official python implementation since there are no extensive docs of the API.

Getting Started

Make sure you have your rust environment configurated

Installation

1. Add library to your Cargo.toml

   ...
   [dependencies]
   blynk_io = "0.3.0"
   

2. Use the library in you code

   use blynk_io::*;
   ...
   let mut blynk = <Blynk>::new("AUTH_TOKEN".to_string());
   
   fn main() {
       loop {
           blynk.run();
           thread::sleep(Duration::from_millis(50));
       }
   }
   

3. Have fun! 😌

Usage

1. Get an AUTH_TOKEN Key with https://blynk.io app
2. Install cargo binary crate to be able to test easily on your computer

   $ cargo install blynk_io
   

3. Run the provided binary example with provided AUTH_TOKEN

   $ blynk_io --features build-binary AUTH_TOKEN
   

   (Optional) if you want to run the client in async mode, start the folllowing example

   $ blynk_io --features build-binary,async AUTH_TOKEN
   

4. You should see an output similar to the followig one
