Getting Started

Register an account using Blynk App, and create a new project.
Use the provided auth token to register your device for use in blynk tools:

> blynk device add 1a5c3988d60f477db6bac3417df7396d --name=CoolDevice1
⠋  Adding device...
●  CoolDevice1

If the device is recognized, it displays it's name and online/offline status. You can add multiple devices.
For more info on device add command, run device add --help.
Now let's check the device status:

> blynk device list
⠋  Refreshing device status...
┌────────┬────────────────┬────────┬───────────┐
│ Status │ Name           │ Server │ Token     │
├────────┼────────────────┼────────┼───────────┤
│ ●      │ PC Remote      │ Blynk  │ ...36a645 │
│ ○      │ Bluetooth test │ Test   │ ...427f4c │
│ ●      │ CoolDevice1    │ Blynk  │ ...f7396d │
└────────┴────────────────┴────────┴───────────┘

We can manipulate virtual pins of your devices (you need to specify either device name or auth token):

> blynk virtualWrite --device=CoolDevice1 V0 123
V0 set to [123]
> blynk virtualRead --device=CoolDevice1 V0
[123]

Many commands in this suite require a --device to be specified.
It may become cumbersome, so let's select the default device:

> blynk config default.device "CoolDevice1"
New default.device value: "CoolDevice1"

Now blynk virtualWrite V0 123 works, and you can also see the default device in the device list:

> blynk device list
┌────────┬────────────────┬────────┬───────────┐
│ Status │ Name           │ Server │ Token     │
├────────┼────────────────┼────────┼───────────┤
│ ●      │ PC Remote      │ Blynk  │ ...36a645 │
│ ○      │ Bluetooth test │ Test   │ ...427f4c │
│ ●  ⇨   │ CoolDevice1    │ Blynk  │ ...f7396d │
└────────┴────────────────┴────────┴───────────┘

For more commands and examples, run blynk [command] --help.

You can also enable command completion on BASH/ZSH/etc:

eval "$( blynk completion )"
