Can HC-05 bluetooth sending data out?

Posted on
  • 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.

  • I use Android phone, however don't know how to change this code you link posted, is any simple example how to send data from Espruino?

  • 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

  • thank you, I wrote that informations from already ;)
