This repo contains a simulation and a Web Bluetooth test using simple Serial-like communication.

To try it, install the following in your computer and BLE device.



First, install the following environment:

And using your freshly improved arduino IDE, install the example in the "firmware" folder.


It requires Chrome (or chromium), and works on almost any OS (android too). The minimum requirements are listed here:

Windows users


Ubuntu 16.04 users

You must update Bluez, the following tutorial should help, but use the version 5.43 (the new ones are missing useful tools):

If it's the 1st time you're using BLE devices with your linux machine, you might need to check that your OS sees your dongle / BLE hardware:


If it's off, you might want to make sure that bluetoothd is started at boot, this tuto should help:

...but this command should allow turning it on at least once:

sudo hciconfig hci0 up

...and don't forget to enable the "Experimental Web Platform features":


If everything works, you should be able to see a counter once connected to your BLE device with this interface:

You can’t perform that action at this time.
