Additional Information
@cuiyanx did you have to update the bluetooth driver using an external SWD debugger? I just flashed the app and when I scan I do see it showed up:
11:5B:5C:46:1A:43 96boards Test beacon
But I can't connect to it.
@jimmy-huang Yes, I update the BLE driver with 96b_carbon_nrf51. If not, you can't connect to 96 board.
@jimmy-huang I test this issue again with ble adapter on master by commit 4b23a47 and get log:

@cuiyanx did you flash it with one of these? https://github.com/blacksphere/blackmagic/wiki, I think we don't have one laying around so we might have to buy one.
@jimmy-huang No, I just have Flyswatter2 JTAG Debugger using Openocd and telnet to flash. And the url may be helpful: https://wiki.ith.intel.com/display/OTCWebQA/ZephyrJS+BKMs
