Part Number: CC3235MODSF

For captive portals there is an RFC standard tools.ietf.org/.../rfc7710

I could not find documentation in CC3235 API or any code/API that would allow me to define/hack it into the system.

Is this feature supported or planned to be supported?

No, a captive portal is not supported currently.

are you trying to connect as client or add this capability to the DHCP server?

You can use network bypass mode (see chapter 6.5.4 in https://www.ti.com/lit/ug/swru455l/swru455l.pdf) or disable DHCP (set IP Address as static) and add your DHCP stack .

I'm currently browsing solutions for captive portal for provisioning mode where the CC3235 acts as AP and a client like a mobile phone connects as STA and would be redirected to the configuration page.

are you sure you need a captive portal for this?

can't the mobile device access directly the "provisioning" page (e.g. to mysimplelink.net/provisioning.html) when it is required?

Also, the device can introduce a special default page (index.html) when it is not connected to a network.

There are many other options. Check the OOB and provisioning examples.

I'm aware of those. But in order to reach the index.html you need an IP address or the MDNS service knowing that it is "configmydevice.net" or ".com"

For devices that are operating via an AP as an STA and the are not designed to do anything without connection the captive portal is a trivial and easiest choice.
Any other solution requires the OEM to document another chapter "how to use the device if it requires provisioning".

With the captive portal the IP/URL index.html could be replaced with an intuitive and automated background process.

I thought you want the captive portal for the CC3235 in an AP role during the provisioning.

Probably, I'm still missing something.

Anyway, as mentioned this is not supported and can be achieved only if using an external stack.

Yes I wanted to have the captive portal when the device is in AP mode (normally is STA connected to AP but the first configuration or if it fails to connect to an AP it needs provisioning, i thought it is clear).

Anyway it would be a nice feature to have since it is a standard.

Thanks. We will consider this in the future.
