Strange BLE connection state

Sometimes, the onConnectionStateChange() callback is called with status 22.
It is said to be a "Bond" error.

But what could be the cause behind it?
And how to avoid it?

22 just means "connection terminated by local host" (defined by the Bluetooth specification). Some examples why the host terminates:

  1. You call disconnect().
  2. The GATT timer times out, which happens if the remote device doesn't respond to a request in 30 seconds.
  3. The SMP timer times out, which happens if the pairing process doesn't make any progress in 30 seconds.
