BLE-web-interface

Displays nearby BLE devices on a webpage served by a Tessel.

You have the option to pre-register devices into the code if you want them to show up with a name next to them.

This could be useful if you just want to know what BLE devices are around you– or if a group of people regularly carry BLE-broadcasting devices (e.g. Fitbits or phones), you could register them into the code and use this for a roll-call of who is present.

Materials

To run

  1. Clone this repo
  2. From inside your local copy of the repo, npm install to install dependencies
  3. Plug the Bluetooth Low Energy Module into port A on your Tessel
  4. Connect Tessel to wifi– this should be the same wifi your computer is connected to. (tessel wifi -n network -p password). Note the IP address of your tessel when it connects (you can also show it again with tessel wifi -l)
  5. Start the server and begin scanning for BLE devices with tessel run index.js
  6. Once the console has logged that it's listening, go to your tessel's IP address in the browser + the port– so in my case, '192.168.8.106:8080'. The page served from your Tessel should appear!
  7. I didn't do anything fancy with this, so you'll have to refresh to get the most recent listing.
