Which one for web client project

[gvida]

Fane of trips on bike, I am working on a project where e-ink reader is the central point as it will be used to display various information like speed, distance and way points needed for the trip. All these information will be prepared by a micro web server hosted on arduino with wifi. (this part is in progress and close to run properly).

The advice I am requesting from you concerns :

I am looking for a ebook reader (kobo, kindle, pocketbook, ..) having such characteristics :

-web browser that can access to the wifi-server without needed to connect to internet.
>>>I have a kindle PW2, it fails when connect to the wifi server as internet is not reachable. Obviously on my bike I will only have the wifi-server with no connection to internet. To solve such issue on kindle, I should jailbrake it but I do not want to do such thing.


-Good response-time when refresh the screen with limited flickers
-minimum 6 inch
-backlight
-jailbracking not mandatory


Hope this is clear

I am looking forward to reading you

I don't know of an ereader that would do that.
For the money spent, I would get me a GPS and bicycle mount.

There's a way around the Kindle network problem. I know of a guy who solved it for his bike computer.

GPS does to cover my need for two reasons:
it does not manage waypoints As I need for a roadbook for rally
screen is too small

my question is basic; which e-ink reader can access to a wifi hotspot tht is not connected itself to www. Kindle does it but control if internet is connected, propably to check things with amazon. the only way should be to jailbreak the kindle, but I do not want to go on this way.

Is someone having a pocketbook able to make such test ?

That looks really cool Nate.

There is no such thing as a backlit eink reader. Eink is opaque. If lighted, they are frontlit.

i'm assuming that the wifi device you are trying to connect to also has a built-in web server. and that you are trying to connect to this web server.

just a guess here, but perhaps the connection is not possible because you are NOT using the direct ip address. if you are trying to connect by using the website name you've set for the device, then your device will also need DNS information. for instance, without DNS, you cannot get to google.com by typing in "google.com" in the url bar. but it is possible to get to google.com by typing 216.58.219.14. and since this device is itself not connected to the internet, it would be unable to use DNS regardless (unless the device also has a DNS server built-in).

The Kobo Aura H2O might be what you want. 6.8" screen and waterproof. The various Kobo devices have been used for similar projects. XCSoar for gliders is one. There was also someone doing something similar for sailing. The Kobo device was accessing a device on the boat that served the speed and other information. The person who was doing this posted a couple of photo's of the result, but I can't find them at the moment.

And as a note, all the current Kobo devices share the same firmware. This is just Linux and doesn't need any real jailbreaking. The networking does check a site before finishing the connection, but there are several ways around this.

wooooa, lot of answers, looks this interests people


Yes the the web server embeds a wifi based on MC arduino and works fine.
The url is the IP address of it. When I test with Ipad, laptop, etc that works fine.

I tried to use a kindle pw2 as web client, but as my web server will never be connected to internet, the connexion fails. I know that the solution would be to jaibraike the kindle to set parameters to avoid this, but I DO NOT WANT to jailbrake the reader.

So KOBO or Pocketbook are fine for me, the first criteria is be able to connect to an ad-hoc wifi-webserver that is not connected to WWW and be able to put as favorite the url to make the launch of the web page easy.

so which one is better for my project from your thoughts ?

Perhaps using a generic eInk Android device, rather than a dedicate reader, might make the job easier? There are several of them around, such as the Boyue T62, Onyx T68, etc.

As Nate's article links to, you can have your Arduino serve the page your Kindle is expecting, but there is a simpler way... and I promise, no jailbreak is required.


Put a plain text file called "WIFI_NO_NET_PROBE" in the root of the userstore.
(That is, "/mnt/us/WIFI_NO_NET_PROBE" in the device's filesystem, but "K:\WIFI_NO_NET_PROBE" when plugged into a Windows PC, or "/media/Kindle/WIFI_NO_NET_PROBE" when plugged into a linux PC.)

There cannot be a .txt extension! (Windows tried to create one automatically, and may hide extensions from you, depending on your settings.)

Now, reboot your Kindle.


What this does: ordinarily, the Kindle probes a wifi-stub page on Amazon's servers, and if it doesn't receive the right response, it assumes the WiFi network is locked with a captive portal. It pops up the message that additional authentication may be required.
This file flag disables that check.

That's not it. From the bike hack article Nate linked:

Another twist peculiar to the Kindle is that when it connects to a new access point, it immediately tries to reach Amazon. If it doesn’t get the right response, it won’t treat the access point as valid. The solution was simple: Have the Pi supply the Kindle with the short response it was expecting from Amazon.
