It´s good that you changed your mind and set it for free. 
But it would be cool if one could directly download it as a PDF.
Currentyl i would have to go to the last page, to get the number of that page and then print it from page 1 on, on a PDF-printer… but you´ll get an error, that you can´t print more then 50 pages in one step…
After 11 steps, which result in 11 pdf-files, one has to put them together, to get the book as a single pdf-file, which isn´t very comfortable. 
Potential new customer here. Unless the tutorial is made as a PDF, I can’t reccomend SiWi to our design team. Simply shocking that the ‘fix’ was to make it an online e-book reader!
Holding back information that should be readily available isn’t going to earn you any customers.
Dear chiptech,
I understand your point, that’s right Sierra Wireless doesn’t have plan to publish a PDF version.
In order to improve Open AT Tutorial Book reading and printing experience, here are some details about the reader:

About the printing, it appears that there are effectively a limitation of 50 pages maximum at a time. Limitation is due to the reader in place. That was not in our initial expectation, there is no restriction from Sierra Wireless to let you manage complete printing of the book.
I invite you to try the bookmark feature which is cool, helping browsing the book and going to expected page immediately.
is this some licensing thing? aren´t you allowed to publish it as a pdf, but as a whatever this might be called?
Thibault,
With all due respect the web SW viewer is a very inefficient (and painful) way of reading the document compared with downloading and reading a PDF. It also mean you have to be on-line whenever you want to read the document - that seems daft!
I know you’ve said
but I believe that’s a backward step. Why on earth can’t you make the “book” available to developers in PDF format for download? Is there some issue with the original publisher of the book?
Eric
Guys, I understand very well all your arguments here.
I’m currently working with the product team in order to find a better solution.
Stay tuned. I’ll keep you posted here.

Hello people,
Even if you want to print the book on paper, it may not work well. On the web site, i have printed a single page on a paper and saw that the pixels were horrible 
Printing quality is not good.
i also have a pdf printer on my windows pc. if i successed a quality copy, i would print all pages 50 by 50 to pdf and merge it for you as a single pdf file. But no luck
I completely agree with the comments on this thread. I have been a member of numerous developer programs starting with Microsoft, continuing through Novel’s DIO program etc. etc. They were put in place to encourage developers to adopt their platforms because they knew that without applications they were dead in the water. And they were enormously successful. When I first saw the Sierra Wireless Developer’s forum I was encouraged. It looked pretty comprehensive. Only on closer inspection did I find that although it looked good it was nearly impossible to put into use by a busy practicing software engineer. In particular the Open AT tutorial is presented in a way that is 1) Not searchable (there is a search box but it won’t accept text!!), 2) no clickable table of contents or index. 3) Not printable. Even though there is a print option you get a blank page. In other words, you have to page through a 508 page document using Abobe reader. Simply not usable.
By not making the document available as a .pdf, by charging for a paper copy of the manual and by implying the only real way to get the documentation necessary to develop code for Open AT is to attend the classes, Sierra is in practice, if not in fact, behaving as though training was a profit opportunity for them as opposed to a way to encourage product sales by expanding the applications for the Fastrack devices.
Sierra Wireless has a very promising product. Open AT looks robust and powerful. But there are a number of companies out there with competing products and the race will go to the company that can build good developer relationships. Please please, get a .pdf copy of the Open AT Tutorial on the site as soon as possible!
Thanks!
Really, it just needs to be a PDF 
It’s a no-brainer - that is the standard, ubiquitous, universally-accepted delivery format.
Dear all,
Hoping that you’ll all enjoy it, the Open AT Tutorial Book is now available as a PDF for download.
Christophe
Excellent
