Ubuntu 15.10 и Globalsat BT-338 Bluetooth GPS - org.bluez. Ошибка. NotAvailable

Я пытаюсь получить свой Bluetooth GPS, подключенный к моему EEE Asus ПК 1201PN.

Я использовал обоих внутренний модуль Bluetooth, а также модуль Bluetooth USB с теми же результатами. Я также загрузился от карты флэш-памяти с 14.04.3 LTS и смог соединить и получить сигнал GPS.

Это - довольно новая установка, и обновленный по состоянию на прошлую ночь.

Кто-либо может дать мне какие-либо подсказки о том, как диагностировать ошибку bluez "NotAvailable"?

Обновление: Я обновил до 16.04 LTS, и проблема остается.

Спасибо.
