What steps will reproduce the problem?
1. Load application.
2. Connect to device.
3. Wait 30 seconds, doing anything or nothing with the app.

What is the expected result?
Device should remain connected.

What happens instead of that?
Device disconnects.

Please provide any additional information below. Attach a screenshot if
possible.
Device reliably disconnects 30 seconds after connecting.  Have tested multiple devices on multiple chrome books, as well as different applications using the same SDK.  Connections with Bluetooth Low Energy work as expected, and connections with Bluetooth Classic work on osX, but connections with Bluetooth Classic on chromebooks exhibit 30 second disconnect behavior.

The event and error that fires is as follows:
eventName: "bluetoothSocket.onReceiveError"
error: "system_error"
errorMessage: "ERR_NOT_IMPLEMENTED"
