pyshark can not handle ATT client and server simultaneously

[utadalight]

For Bluetooth ATT, a client can only send a request, and can not send another one until it received the response for last request. When a device supports both ATT client and ATT server simultaneously, it means it can send out 2 packets without wait for packet from remote, one is a request as a ATT client, and the other is a response as a ATT server. It seems that pyshark can not handle this scenario properly
