Captive portal for ESP-32

General
1

I am trying to create a captive portal for and ESP-32. I am starting with

https://mongoose.ws/tutorials/captive-dns-portal/

I can’t compile the cut and pasted event handler.

Is there a library I need to include? Is there a better approach?

Thanks!

That tutorial is for the mongoose network library, not for Mongoose OS.
Mongoose OS uses this branch of the mongoose network library.

Hi nliviu,

Thanks for your help. I got it working with Firefox, Chrome, Edge and Safari using DNS port 53.

I think this tutorial is a little out of date. I had to change to the 4 parameter connection and evhandler to get it to work, as follows:

static void ev_handler(struct mg_connection *nc, int ev, void *ev_data, void *ud)
nc = mg_bind(&mgr, s_listening_addr, ev_handler, NULL))

Mongoose is one thing, Mongoose-OS is another thing. Mongoose-OS is based on one mature version of Mongoose.
The tutorial has been written for Mongoose, not for the particular version that Mongoose-OS uses (the one whose branch Liviu referred you to).
If you are using the latest version of Mongoose (outside of Mongoose-OS, of course) and found an actual problem with the tutorial, please report it at the Mongoose website, not here.
