Unfortunately, the web browser on the Kobo devices doesn't support a lot of function that is needed for modern web sites. Looking at that page, it needs more function and power than the Kobo devices will have.

Don't know if this would help you in any way but here's the debug message when visiting the demo site:

Code:

Nov  1 14:26:39 nickel: (  5335.603 @ 0x4c7898 / ui.debug) "http://demo.signalk.org/admin/:1: Viewport argument key "shrink-to-fit" not recognized and ignored." 
Nov  1 14:26:41 nickel: (  5337.170 @ 0x4c7898 / ui.debug) "http://demo.signalk.org/admin/index.bundle.js:19: ReferenceError: Can't find variable: Set"

So the Kobo browser takes offense to the JavaScript on that site... and going to https://developer.mozilla.org/en-US/...al_Objects/Set also doesn't work one bit on the Kobo

Basically it's not a good idea to run heavy javascripts browser apps. Keep it simple

You might be able to adapt the XCsoar software. A description here. You could search for "XCsoar Kobo". Mod description (with 3d printed parts)

You can use my WebPortal mod to run HTML+JS+CGI stuff in the Kobo browser (from localhost, http://127.0.0.1 or http://webportal).

However, the Kindle app shown in their screenshot won't work on Kobo browser either.

So this kindle script is trying to use localStorage which is apparently, not available on Kobo. And without local storage you can not configure server.

And once you fix the localStorage thing (just a few settings you can just as well put in the file directly), another problem is likely to come up, so it probably just won't work.

changed localStorage to cookies and next problem

I give up on it at this point, sorry

Think you to have tested thé app have a good day

chech · 11-05-2018, 08:49 AM

Hello i don t know thé way to connect intranet i see tour post for kobo.com but i don t understand thé buildininfo.xml What this think you i want to connect at one hotspot whith no internet thinks a lot

chech · 11-05-2018, 08:53 AM

It IS possible to connect thé brosser kobo to accès point whith no internet raspberry pi 3 whith openplotter its os dedied to sailling its easy whith smartphone but impossible with kobo reader for What

frostschutz · 11-05-2018, 09:05 AM

for intranet connection, you can

- download my WebPortal mod
- edit .addons/webportal/vhosts.conf
- add www.msftncsi.com www.kobo.com to vhosts.conf
- download www.msftncsi.com/ncsi.txt and www.kobo.com/buildinfo.xml and place in .addons/webportal dir
- reboot

After reboot, when Kobo firmware checks for www.msftncsi.com/ncsi.txt (old firmware) or www.kobo.com/buildinfo.xml (new firmware), it should find the locally served file instead and proceed with the connection.

( I should update the WebPortal mod to include a separate archive with this hack pre-enabled to make it easier... )

I'm not sure if there is another patch for intranet wifi that doesn't involve WebPortal

chech · 11-05-2018, 04:39 PM

Thinks you web portal ok connections ok now testing with openplotter its thé way
