Re: [lwip-users] TCP packet out-of-order

Sergio, Thanks for your reply

Here is the capture: https://www.dataq.com/exchange/outoforder.pcapng

I am using raw APIs without RTOS, and all outputs are done in callbacks.

So far, I can communicate with lwip after the incident.

Sometimes it takes a long time to run before this happens, and I have to 
stop and resume wireshark a few times to minimize the disk consumption
