I try to use SDK8.1.1 example connect ubuntu14.4 with CSR dongle. Seems it create connection fail. I downgrade to SDK7.1, it connection pair correctly. But it'll terminate connection once finish pair.

Here is hcidump

But at last, after long press button0, mouse disconnect gracefully. Then even after reconnect successful, press button0 have no effect.Till reboot PC.

Keypad have same issue with mouse. If long press button0 or press button0 very fast(it'll treat as long press), will disconnect. Even after reconnect ok, keyboard button0 can't say hello again. I can't see problem on host side, but problem really happen at someplace.
