system halted when disconnect the bluetooth

[Milk]

The device use SDK9.0,during the using of device,when disconnect the bluetooth of phone system sometimes,the system halted.

So I make an experiment about the probability of the situation happened,generated a android app: connect the device successfully,then disconnect the device,the connect the device,again and again,

The result is the system halt don't happened,So I doubt this is the problem of SDK9.0, Is there the system halt bug in the SDK9.0?

Which example are you using? How are you disconnecting? In some situations Android keeps the connection at the system level, even though you have closed the app.

Hi, I use the example of ble_app_hrs,press the app button("disconnect" )to realize the device disconnecting.
