Re: [threadx-dev] Technical support question?

Hi Snorri.

Yes, this is the right place for such questions. 

You will find the documentation for the DHCP client here: https://github.com/eclipse-threadx/rtos-docs/blob/80bd9fe9a33fa79257c75629be1b4438b84db7bc/rtos-docs/netx-duo/netx-duo-dns

I am no expert, but from what I understand, the name you give to the DHCP client instance seems to be used as the hostname. 

UINT nx_dhcp_create(
    NX_DHCP *dhcp_ptr,
    NX_IP *ip_ptr,
    CHAR *name_ptr);

Line 6784 in nxd_dhcp_client.c sets the proper option and the value for dhcp_ptr -> nx_dhcp_name comes from *name_ptr in the method above.

 _nx_dhcp_add_option_string(buffer, NX_DHCP_OPTION_HOST_NAME, name_length, (UCHAR *) dhcp_ptr -> nx_dhcp_name, &index);

Best,

Hello devs,

Where can I ask a technical question?

Is this the correct place?

In short - I need to know how to set the hostname for a (DHCP enabled) device that is running the ThreadX - NetX DUO network stack.
