Public bug reported:
Bluetooth connection to a bluetooth IOIO device fails using a USB bluetooth adapter from a Ubuntu 16.04 system. The same device could be successfully connected using two non-Ubuntu systems:
a) The same system hardware setup (dual-boot) running Windows 8 could connect without any problems. Also could run applications using serial-port associated with this connection.
b) Android Note 4 device using bluetooth was able to successfully connect and run apps.
Therefore, it was concluded that the Ubuntu 16.04 bluetooth service has
Note: The USB bluetooth adapter used: BTA8000 from Cirago on the ubuntu
system as well as the IOIO device. The adapters on the device and system
have been verified to have different MAC addresses and works well with
Procedure: Using the Bluetooth control in system-tray -> Bluetooth
settings -> +, the device was located as IOIO (8A:22). Here, device was
clicked upon, changed PIN to 4545 and pressing next resulted in the
device being successfully added. However, the system-tray status of the
device continues to say Connection is OFF. Attempting to turnon
connection results in changing the system-tray blue-tooth icon to Keys-
Icon for few seconds and then reverting back to the bluetooth icon. The
device remains in disconnected state and cannot be accessed.
The btmon trace (log-line 1277) and bluetoothd syslog (log-line 405)
logs seem to indicate that the local host is sending a disconnect
request after receiving a SDP: Service Search Attribute Response from
the device. The src/device.c:connect_profiles()
/org/bluez/hci0/dev_00_1B_DC_06_8A_22 (all), client :1.73 must result in
connection setup - not disconnect.
Log information was collected for the above procedure.
