change sdk v2.6.1 to sdk v2.7.0 after websock not able connect with server

[ChiragBhavsar]

In SDK v2.6.1, commenting out the following code in websocket.c allows successful connection to the WebSocket. However, in SDK v2.7.0, even after commenting out the same code, I am still unable to connect to the WebSocket.

if (!(ctx->all_received && ctx->sec_accept_ok)) {

NET_DBG("[%p] WS handshake failed (%d/%d)", ctx,

ctx->all_received, ctx->sec_accept_ok);

ret = -ECONNABORTED;

goto out;

}

Hi,

Are you using an SDK sample, or is it a custom project?

Please share the device logs.

I recommend fixing the issue causing the WebSocket handshake to fail rather than commenting out the check.

Hi,

websock4 = websocket_connect(sock1, &req, timeout, "IPv4"); //SYS_FOREVER_MS

if (websock4 < 0) {

LOG_ERR("Cannot connect to %s:%d", WEB_HOSTNAME,

WEB_PORT);

return 1;

//close(sock1);

}

i used websocket_connect and i get the error,

i check sdk v2.7.0 release not but i did't get any thing related to websocket,
i have require to do any change in prj.conf?

Hi,

You connect to echo.thingy.rocks and not a dedicated websocket. Have you tried connecting to a server using websocket instead?

Is there a reason you want to use a websocket instead of a regular socket?

Best regards,
Marte

Hi,

We tried connecting to echo.websocket.org and were able to establish a connection using SDK v2.6.1, but it does not work with v2.7.0.

We are developing a product for our client, who uses a personal server. We want to connect to this server using WebSockets and receive data from it.

can you please ask me is there any change in websocket driver side in sdk v2.7.0 ?

[Marte Myrvold]

Hi,

The websocket library was converted to use zsock API.

The nRF Connect SDK v2.6.1 uses v3.5.99-ncs1-1 of Zephyr, and v2.7.0 uses v3.6.99-ncs2 of Zephyr. So you can compare this two tags to see all the changes.

I would recommend looking at the WebSocket Client sample in Zephyr.

Best regards,
Marte
