Hello,
When I send an TCP packet (1022 bytes) from my PC, I receive the packet in 2 times (with TCP_EVT_DATA). 536 bytes first and 486 bytes.
I don't understand why I can't receive it in one time.
Anybody can help me ?
Thanks.
My sniffer says one packet with 1022 bytes
What version of RL-ARM are you using?
The latest (4.10) has a 'solved problem' stating:
Added: MSS option (maximum segment size) to SYN packet for outgoing TCP connections. Because this option was missing, PC used reduced segment size of 536 bytes in communication.

Aaaaah it seems be the problem.....thank you
Is it possible to have the patch to solve the problem ?
If you have an active license, then you can get the update via:

I don't have an active licence........
The "nice" thing about the RL-ARM is that you don't get the full source code to the library - you have to pay extra for the TCP/IP code.
So having the support agreement expire means that you can't just fix the code yourself.
And it's not just a little extra!
I got a quote and very quickly decided not to bother wasting my time asking for a purchase approval.
