Intermittently after booting the porter board, selecting Settings and the Bluetooth view (with BT already enabled by default) previously paired and locally visible devices will fail to be shown in the device list. Further, a number of unpaired devices that are normally visible will also fail to be shown.

Disabling/enabling the bluetooth toggle switch on both the handset or the settings/bluetooth switch do nothing to fix this.

Even when my phone is not visible in the list, since it's paired I find I'm still able to select/connect to the porter board from the phone. This seems to indicate that the actual bluetooth binding is operational at some level.
