Hello, i’m on a project wich is the creation of lazer game of mini tanks that we want to be controled by bluetooth. As so i’m using an arduino and a hc05 to be connected to my phone. However the reason i am contacting you for is that now i create my project on blynk but it would never pair to the hc05, when i’m pressing the bluetooth button, i choose my hc05, they ask me the password to pair, i write it but then they show this message every time : can’t connect connecting to bluetooth devices , or sometimes it tells me to retry later on
i don’t understand i’m doing exactly the same thing as all the internet tutorial, i uploaded your library, i pressing the same button but it doesn’t work,
I would grandement appreciate your help
Are you talking about the Bluetooth widget in the Blynk app?

yes I am
Have you read this comment in the sketch builder example:
You may need to pair the module with your smartphone
via Bluetooth settings. Default pairing password is 1234
