This peripheral provides an outline for simple door open/close management over Bluetooth LE. The BTLE service and characteristics are implemented, but the authentication and actual door opening components are stubbed in. These are what would need to be implemented.
Install dependencies:
npm install
On OSX you can start with:
node peripheral.js
On Linux you need to super user privileges:
sudo peripheral.js
Use the ALLOWED_FILE environment variable to tell the peripheral where it can perform a lookup for a given auth token:
ALLOWED_FILE=/path/to/allowed.json
The ALLOWED_FILE should contain the auth token as keys, e.g.:
{ "abc123": "bob@example.com", "def135": "bev@example.com" }
Set up the DEBUG=door environment variable, e.g.:
DEBUG=door node peripheral.js
To see additional DEBUG output used in the underlying bleno library use the following:
DEBUG=door,bleno,hci-ble,l2cap-ble node ./peripheral.js
- DoorService
The DoorService provides a single characteristic, DoorAuthCharacteristic, which can be read or written to (without response).
Write your secret to the DoorAuthCharacteristic and if it's the proper secret you will be granted access. If not, you will be ignored.
If you read the DoorAuthCharacteristic it provides no meanginful information outside of it telling you it's a door.
