@technobly Please verify SoftAP continues working as normal (with tinker), and then flash the app above and try it out. You should see custom pages for setting up wifi.

Both WICED and SoftAP changes look good to me. Setting of wifi credentials works with both Particle's mobile app (with tinker flashed) and custom HTTP handler.

@sergeuz, did you managed to get the code above working? I would love to use the softAP page for a project demo but is short of getting the softAP page to work.

I needed an extra #include "softap_http.h and the demo app compiles fine. My photon connects to the ☁️ (breathing cyan) and i see a Photon SSID but is unable to connect to it.

Just tried. http://192.168.0.1/version works but not http://192.168.0.1/index.html in listening mode.

Also, the photon exited listening mode and ran user code after i called ``http://192.168.0.1/version`. Not sure if this is the default behavior

Could you try moving call to softap_set_application_page_handler() from setup() to STARTUP(), e.g.:

STARTUP(softap_set_application_page_handler(myPage, nullptr));

void setup() {
}

void loop() {
}

Listening mode might have been enabled before calling setup() in your case, which typically happens when the device has no wifi credentials configured.

@sergeuz, yup! That did the trick... But the photon would automatically reboot after the page loads. Seems like more work needs to be done for this to be stable?

sergeuz commented Mar 24, 2016

So you were unable to set wifi credentials via custom page due to unexpected reboot? Besides of missing include and STARTUP(), did you make any changes to above application?

SoftAP worked normally in my tests, but I'm going to check it once again if the problem still persists.

kennethlimcp commented Mar 25, 2016

Nope i only added #include "softap_http.h and moved the call to STARTUP that's all. I see that index.html works but the device ends up rebooting. I think softAP setup worked on but not when you are browsing with a browser

I wasn't able to reproduce the problem. What OS do you use? If it's Ubuntu then its automatic modem probing may cause Photon's listening loop to exit early (and shut down SoftAP).

I just tried it with Particle Build and hence got bitten by the preprocessor.
And I had tried #include <string.h> and got a different set of errors which made me try the preprocessor pragma.

MORA99 commented Apr 6, 2016

ahh, it happens when the browser accesses favicon.ico (for the site icon).
Adding a empty page at that address allows the scan to complete.

{ "/favicon.ico", "text/html", "" },

Ideally a lightweight particle icon could be used :)

Should idx not be a int ?

uint8_t idx = 0;
...
    if (idx==-1) {
        cb(cbArg, 0, 404, nullptr, nullptr);
    }

That also prevents the error.

I'm seeing what looks like a compiler issue. If I build the system firmware locally it works fine, but when I use the one from the cloud it fails.

@MORA99

MORA99 commented Apr 7, 2016

Maybe the 2 compilers handle the unsigned issue differently ?

idx is declared as an unsigned int (8).
But then its set to -1 if the page is not found.
And later compared to -1 to know if a 404 (page not found) should be sent.

Declaring it as int8_t instead solves it on the webide.

m-mcgowan commented Apr 7, 2016

Good ideas, but sadly it's not that - I keep the same application binary but just change the system firmware, and that causes the fault.

@MORA99

MORA99 commented Apr 7, 2016

Ok, but the code is wrong anyway, a smal oversight, but enough to make it fail.

Setting a unsigned value to -1 (which is not a valid value for unsigned) and then comparing it to -1, will only work if the compiler treats that -1 as a uint8_t also.
Otherwise the code fails to see the page requested does not exist, and then accesses the myPages array with a bad index.

I just retested the code with web ide, and that small unsigned change is the difference between red sos on unknown page or a working softAP webpage process for me.

I am using google android browser, but to test I just accessed favicon.ico directly, when using uint8_t it goes to sos, when using int8_t I get a blank page as expected.

Contributor

m-mcgowan commented May 5, 2016

No sorry, it wouldn't work as is with a captive portal, as it's a different set of technology from what's being presented here. The captive portal is created by the external access point (which then may eventually time out the wifi connection if the user doesn't sign up/login etc..), while the http pages here are provided by the Photon's own internal access point.

Buuuut...this got me thinking. In a future update, we could have the photon connect to the open network's captive portal (as a regular WiFi client), and simultaneously route the webpages presented via the SoftAP interface to the device that was already setting up the photon via HTTP. This would then allow the user to complete the signup or whatever is needed by the captive portal in order for it to whitelist the Photon's MAC address.

At present the photon doesn't allow it to be both a wifi client and an access point so we can'd do this now. However, I am in the process of making that possible, so this would then be workable in practice!
