Realtime updates with Websocket video and Documentation don't match.

[rossack]

I want to use websockets for realtime updates from a PicoW ADC, so I followed the Realtime updates with Websockets video. However in the Wizard UI builder, when I set a text element value to ${websocket.value1} and gauge element API variable to websocket.value2 the UI builder says ERROR: invalid expression, invalid API reference. Also, the video tutorial shows copying this code from the documentation:
mongoose_add_ws_handler(200, ws_200) ;
where the ws_200() callback parameter is mg_connection *. But when I look at the documentation on the web site the websocket sample code is:

static void my_getter(struct real_time_data *data) {
  data->value1 = read_adc();
}
.......
mongoose_set_http_handlers("real_time_data", my_getter, NULL);
mongoose_add_ws_reporter(200, "real_time_data");

I can see the web client sending the ws://192.168.0.170/websocket requests but the server doesnt respond.
Any help greatly appreciated.

It appears the Wizard-specific WebSocket is a simplified(?) version of the raw Mongoose websockets. The Wizard sets WIZARD_ENABLE_WEBSOCKET=1 in the mongoose_glue.h file as well as declaring these two functions:

void mongoose_add_ws_handler(unsigned ms, void (*)(struct mg_connection *));
void mongoose_add_ws_reporter(unsigned ms, const char *name);

So I assume that's all we need to send data to a web client. BUT, in mongoose_impl.c mongoose_add_ws_handler() function gets compiled out.

I dont get it??!

Hello, this is the Mongoose repository. Here we develop the code for the Mongoose library, Wizard usage issues or questions do not belong here.

Thank you.
