Hello. I’m using Arduino Nano, with HC-06. I don’t have any shields. On my phone i have the latest version of app. Anroid, btw. Also in my project I have latest Blynk library. I’m not using any local servers or something else. So HC-06 works properly, i tried it in other project without Blynk. But when I’m using any code from example, i don’t receive anything from arduino. For example, i have code like this:
/*************************************************************
Download latest Blynk library here:

Blynk is a platform with iOS and Android apps to control
Arduino, Raspberry Pi and the likes over the Internet.
You can easily build graphic interfaces for all your
projects by simply dragging and dropping widgets.

Sketch generator: http://examples.blynk.cc

Blynk library is licensed under MIT license
This example code is in public domain.
*************************************************************
Note: This only works on Android!
iOS does not support Bluetooth 2.0 Serial Port Profile
You may need to pair the module with your smartphone
via Bluetooth settings. Default pairing password is 1234
Feel free to apply it to any other example. It's simple!
NOTE: Bluetooth support is in beta!
You can send/receive any data using WidgetTerminal object.
App project setup:
Terminal widget attached to Virtual Pin V1

Thx for help, I didn’t noticed that. I just copied that from example. But why is that in examples? Looks strange. So i deleted other things, but it still doesn’t work:

Okey, I noticed that code from example is for BLE, but HC-06 doesn’t support it. I took code from that example:
And now it’s looks like that:

But it still doesn’t work. Thats what it’s saying in terminal:
