Hello.

I try connect gear to gear using bluetooth.

But connection is failed.

First, both side get

‘vent-handler.c: __bt_device_event_filter(783) > BT_DEVICE_CONNECTED’

log when client call connect with right options.

If not call connect, this log not appear.

Below is full log after above log.

Server side
