Beginning LoRa Radio Networks with Arduino: Build Long Range, Low Power Wireless IoT Networks

This book is a great introduction to LoRa for Arduino users. Easy to follow, with accurate list of materials material. Both beginners and advanced users will find value information to create its own Lora nodes and interesting applications. Nowadays all the LoRa information is spread on the internet, so it's easy to get lost. We have the luck to count on this book to guide us. There are few books about LoRa and Arduino on paper edition today, and I can say this is the best one I have read and it is also up to date (edited 2019).Highly recommended if you want to dive on the LoRa secrets.

I don’t usually leave reviews, but this warrants one.If you’re not a “I know nothing Beginner in 2022ish” don’t waste your money..All the information in this book could be summed up in a chapter or two. Everything else is telling you what to buy and will quickly be outdated..Over half the book is download this, install this, click run, make sure the power is on type stuff..

I love to read, I love to learn, I love technology and I love radios. It takes a lot to make me hate a book. This is my first negative Amazon book review in quite a few years. I actually feel ripped off.There is about 10-20 pages of solid, useful content in this book. Unfortunately, it's scattered among 300 pages of irrelevant, page-filler, plagiarized, and literal empty space.Since literally MOST OF THE BOOK is this kind of useless junk, I'm going to only be able to summarize the, er, highlights.- The entirety of page 69 is a screenshot of the Windows launch menu (aka Start Menu, in general).- Not to be outdone, page 68 consists entirely of photos showing you how to plug in a USB cable. I wish I was kidding.- And equally annoying, most of page 54 is taken up by a photo of a USB power supply. You know, the kind that EVERYONE has to charge their phones? Yep. That. It's Figure 2-27!- Not to be outdone in the USB department, half of page 43 is, I kid you not, a photo of a USB cable. Just a regular USB cable.- I read the text on page 16, saying "single-channel LoRa gateways can be built with the same chipsets designed for the end devices (Table 1-3)." I looked at that table and thought - how is this different from table 1-1 from ONE PAGE EARLIER? And the answer: it's a copy and paste. They only changed the heading.- Starting on page 17, we have 5 pages of photos of LoRa gateways. Do we have a comparison between them? No. Only a note on page 21 that multi-channel gateways are more expensive, so "in this book we will focus on building single-channel LoRa gateways." Unfortunately, the authors note on page 13 that only multichannel gateways are LoRaWAN-compatible. Ugh.- Chapter 3, which covers pages 63 - 98, is mostly filled with screenshots of installing software on Windows. Among the highlights I haven't already mentioned from this section is page 75, which is taken up by a screenshot of the "you've successfully installed the driver" screen.- Page 249 is a screenshot of a webpage with a single button to click. The entire page is a screenshot and a sentence saying to click it.- In fact, the majority of chapters 7 and 8 consist of instructions for what to type into forms on websites, followed by screenshots of THE EXACT SAME THING.- The large photo of a plastic bag on page 30 is somewhat entertaining, at least.- The description of the Dragino LG01 on page 58 struck me as really odd -- it was reintroducing LoRa concepts that had already been covered earlier in the book, saying in part "The LoRa wireless allows users to send data and reach extremely long ranges at low data rates." Well yes, we've established this already repeatedly. It was so odd that I googled the text, and found it was plagiarized from the Dragino wiki.- The entirety of Appendix A - all 13 pages of it - is copied directly from the LoRa Alliance website - and the authors (for once) actually give the URL for the document.- I put a few photos above, but literally almost the WHOLE BOOK is like this. I'm not kidding.Inexplicably for a book that came out in 2019, the screenshots are from Windows 8, not Windows 10, which was released in 2015.You might say, "But this is a book for beginners!" Perhaps, but it spends far more pages talking about installing Windows software and showing you USB cables than it does about how to solder (despite multiple instructions to do so, it doesn't describe it at all) or how to use the C code that is presented. (There is SOME explanation of that, but it is not really suited for a beginner.) I'd really like to meet these hordes of people that apparently are seasoned with both C and soldering but don't know how to use the Start Menu. I'm sorry, but if you aren't capable of plugging in a USB cable or using the Start Menu, then I don't think Arduino is going to be for you.There are a few bits of useful information. The parts lists were useful, the bits about how to assemble the hardware were useful, and some parts of the chapters at the end were useful - though all of these were laden with so much redundant and useless information it lessened the impact.All in all, I learned very little from this book and am hugely disappointed in it. It's a fantastic topic and I was really looking forward to it.

The problem is not the book, the writing, or the author. The problem is the subject.An Arduino compares to a baja bug with a single port 1500 engine. too little, old and slow. great as a toy, if you live where you can play in the dirt within seconds. in no way practical, incapable of real work.The cost of an Arduino clone and the Adafruit module you need to do LoRa is more than the cost of an ESP32 with a built in LoRa radio, WiFi, Bluetooth and a tiny OLED display. An ESP32, compared to an Arduino, is a 4WD Bronco with a 5.4L fuel injected V8.Arduinos are fine entry level platforms for learning how to use the various interfaces and the programming language and the IDE. They are notso hotso at doing real grownup work. If you put a Dragino LoRa shield on an UNO you end up with pins 3, 4,and 5 available, and analog pins A0 - A7. If you put a GPS on that, and use 3 & 4 for Software serial, 5 for the PPS - you have 6 not especially useful pins leftIt is also about LoRa, versus LoRaWAN. the problem here is that you get very limited utility out of a single or dual channel LoRa Gateway. to get full service you need an 8 channel concentrator. everybody who tries a homebrew LoRa gateway ( there is no reason not to, given the price of an ESP32 with LoRa ) ends up buying a commercial gateway. commercial LoRa gateways cost ~$120. A commercial 8 channel concentrator costs ~$200. dude, if you're going to be a bear, be a grizzly. Buy a RAK7244. good luck setting it up as a LoRa gateway; if you find a way to make it wok, let me know.

The book also tells how to use raspberry pi.

Everything in this book can be downloaded from either The Things Network, or a LoRa module manufacturer. A complete and utter waste of money.There is no discussion of the LoRa protocol, the LoRaWAN protocol, how to set up in any location that uses 915MHz (since the examples in the book won't work at 915MHz - they will require the Hybrid model), what the message length limitations are, etc.You won't learn anything from this book, and you'll be left with the mistaken impression that you'll be able to do anything more than the downloaded (from the manufacturers) scripts.

Um livro para montar um ponto de acesso para IOT.

A very well put book , BUT the gateway project , do not build as it’s a waste of time as the software has not been supported and many People, as I have done have built it to find it will not work, a lot of money and time wasted. This should be noted in the sale of the book

O livro é muito bom, te explica o passo a passo de maneira clara com imagens. Se o seu interesse for montar uma rede Lora IOT este livro irá te ajudar.*ENTRETANTO* este livro não detalha o que de fato é o protocolo LORA, apenas cita as informações básicas do que é, como funciona e algumas caracteristicas.Se você tem o interesse em estudar a teoria(como montar o protocolo em si) este livro nao aborta este tema.Guilherme CasagrandeEng.
