espconn_sent_cb with multiple queued packets

[Anki]

I am using a UDP espconn to send data and have a espconn_sent_callback registered so I can free the packet buffer after it has been sent. Unfortunately, the only argument to espconn_sent_callback is the espconn so if I have queued multiple packets by calls to espconn_sent, how do I know which one of them has been sent? Are UDP packets guaranteed to be sent in the order they were queued?

yes, they will be sent in the order.
