STM32H5 - NetX Duo - Custom layer 2 ethernet protocol

Question

Hi,

Thanks in advance for your attention.

I'm developing an application using STM32H5 and NetXDuo TCP/IP stack.
I was wondering if in NetXDuo there is a way to handle a custom layer 2 protocol.
This could allow to handle a custom ethernet protocol with a custom EthType in parallel with IP and upper layers protocols.
In my application this would allow to run some custom protocols in a LAN where the device (STM32H5) will operate, such as a custom discovery, keep-alive, ...

Thanks,

Luca

Did you check these docs Functional Components of Azure RTOS NetX Duo and Overview of Azure RTOS NetX Duo already?

NetXDuo TCP/IP stack does support custom layer 2 protocols, and it is possible to handle a custom Ethernet protocol with a custom EthType in parallel with IP and upper layers protocols.

To implement this, you can use the NetXDuo TCP/IP stack APIs to create a custom Ethernet driver that handles the custom EthType. You can refer to the above documentation for NetXDuo TCP/IP stack to get more detailed information on how to implement custom layer 2 protocols.
