Hi,

Could you please give us the maximum received packet size supported by Azure NetX/NetxDuo ? I tried to receive 2000 bytes but without success despite the Hardware allow that and I can do it with LWIP! Is-it possible to modify the Azure Netx stack to support receiving 2000 bytes?

Best Regards,
BM

    The maximum packet size depends on your NetX driver. Typically these are set to 1500 or a value around that limit.
    Which microprocessor and network interface are you using?
    Normally 1500 bytes is not a limitation, add-ons and protocols built on top of NetX can work with a variable packet size. What is your use case?

    Could you please check whether IP fragmentation is enabled or not? By default, IP fragmentation is disabled. You will need to call nx_ip_fragment_enable() in your application. Read more from user guide. If you are trying to ping device which is ICMP protocol, you will also need to enable ICMP by nxd_icmp_enable().
