BluetoothGattCallback - onConnectionStateChange 返回状态 40

Question

状态 40 代表什么？我正在尝试连接到 android 蓝牙应用程序中的设备并获取状态：40？该值是十进制还是十六进制？

如果它是十六进制蓝牙规范，则说明该错误：

COARSE CLOCK ADJUSTMENT REJECTED BUT WILL
TRY TO ADJUST USING CLOCK DRAGGING (0x40)
The Coarse Clock Adjustment Rejected but Will Try to Adjust Using Clock
Dragging error code indicates that the master, at this time, is unable to make a
coarse adjustment to the piconet clock, using the supplied parameters. Instead
the master will attempt to move the clock using clock dragging.

否则，如果它是十进制，它会这样说；

INSTANT PASSED (0x28)
The Instant Passed error code indicates that an LMP PDU or LL PDU that
includes an instant cannot be performed because the instant when this would
have occurred has passed.

它是什么？？
