Yes, the glasses use the standard Android supported bluetooth profiles up to API level 17. Therefore, most mice, keyboards, joysticks, audio headsets, speakers, and RFCOMM compliant devices will work.
API level 17 (Android 4.2.2) introduced a new Bluetooth stack optimized for use with Android devices. The new Bluetooth stack developed in collaboration between Google and Broadcom replaces the stack based on BlueZ and provides improved compatibility and reliability. Besides standard HID devices, headsets, A2DP audio and Health Devices are supported. Also, you can use a standard RFCOMM channel approach if you have your own proprietary bluetooth device you are developing. For example, we built an Android App that runs on any Android smartphone that can provide touch screen and keyboard input to the glasses using RFCOMM channel protocol.
