Re: echo_client and echo_server run in the same board

Hi Diana,

I just tried this and you can certainly enable client and server at the
same time. The compile error you are seeing is because you have
disabled TCP.

The https://github.com/zephyrproject-rtos/zephyr/pull/7653 will fix the
compile error.

Hello,

I am currently trying to run an nrf52 board as both client and server
at the same time (based on echo_client and echo_server samples). I've
gone through their configuration files, and have found that
CONFIG_NET_APP_CLIENT=y is enabled in the client, and
CONFIG_NET_APP_SERVER=y is enabled in the server. According to
Zephyr's documentation, this configurations need to be set to "y" to
enable the respective client and server's net app library APIs.
However, when enabling both CONFIG_NET_APP_SERVER=y and
CONFIG_NET_APP_CLIENT=y, the following errors appear:

In function ‘close_net_ctx’:
/home/user/zephyr/subsys/net/lib/app/client.c:279:19: error: ‘struct
<anonymous>’ has no member named ‘net_ctxs’
if (ctx->server.net_ctxs[i]) {
^
/home/user/zephyr/subsys/net/lib/app/client.c:280:32: error: ‘struct
<anonymous>’ has no member named ‘net_ctxs’
net_context_put(ctx->server.net_ctxs[i]);
^
/home/user/zephyr/subsys/net/lib/app/client.c:281:16: error: ‘struct
<anonymous>’ has no member named ‘net_ctxs’
ctx->server.net_ctxs[i] = NULL;

Is it impossible to run both client and server in the same board at
the same time? or is there a way to get around this problem?
I was thinking on running the client in a thread, and the server in
another thread, but that would still imply having both
CONFIG_NET_APP_SERVER=y and CONFIG_NET_APP_CLIENT=y enabled in the
prj.conf file.

Thank you in advance for your help.

Best regards,
Diana
