Hi, is it possible to send some data by Espruino and HC-05 module eg. into mobile?
there is plenty apps that use bluetooth data, I would like to use it for variometer apps,
need to send data from pressure sensor into it

You can send data from HC-05 bluetooth to Android phones - like this

Apple pretty much deliberately blocked all bluetooth serial modules on iPhone though, so I'm afraid you're out of luck there.

... just to add, you could do something with an HM-10 module I believe (which is bluetooth low energy, which iOS does support) - but it's more difficult.

To send data from Espruino, you literally just do Serial1.print("Hello") once Serial1 is at 9600 baud. Install an app called BlueTerm on your Android phone and you should be able to see the data. Some details are at http://www.espruino.com/Bluetooth
