how to create multiple endpoints in the same channel

[siliangZ]

I am working in an environment that I have an application running in Linux system and an RTOS application running on another processor. I am able to create the rpmsg channel and use the default endpoint to send messages between two applications back and forth.
But I have some problems creating another endpoint on the same channel.
I am using rpmsg_create_ept to create the endpoint in the RTOS application. I think because of the name announcement service, it will not only create an endpoint, it also creates the rpmsg channel. I don't know how to disable the name announcement. And I can't find a function to just create an endpoint without creating a new channel.
If you know how to make it work, I would really appreciate your response.

Hello @siliangQ

The condition to send an ns annoucement is here rpmsg_create_ept

/* Send NS announcement to remote processor */
if (ept->name[0] && rdev->support_ns &&
    ept->dest_addr == RPMSG_ADDR_ANY)
	status = rpmsg_send_ns_message(ept, RPMSG_NS_CREATE);

to sum-up if you don't want to use ns annoucement you can:

• not define the associated name service,
• fix the default destination endpoint address (ept->dest_addr) you want to communicate to.
