Description

When I set my BLE module as the peripheral mode and run the echo example.

If I subscribe the indication and then unsubscribe it, the following error will occur.

root: /home/ubuntu/test/node_modules/bleno/lib/hci-socket/gatt.js:914 handleAttribute.emit('unsubscribe'); ^ TypeError: Object # has no method 'emit'

Contributor guide

Research direction
Investigate the gatt.js file around line 914 to see why handleAttribute does not have the 'emit' method. The object likely needs to be an EventEmitter or have its prototype set correctly.
