I have spent numerous hours in reading articles and watching Youtube video’s.
Now I’m having a good understanding of what Lora, LoraWan and TTN implies and would like to get my hands dirty with some hands-on experience.
For this, I would like to start small and simple; connect a node to an existing Gateway.
Although I have good programming and soldering experience I would like to start with a “known-good” setup, or at least a setup which is guaranteed to work.
Understand I’m not the first one with such question but I’m really stuck in all the options. All solutions I have found come with drawbacks and it looks like there’s no silver bullet available
The Things Node looks ideal, but no longer produced. Would it make sense to try to find one?
TTGO boards, examples which I have found needs to be ported from Platform.io and are not always compatible with the different board revisions.
Some reference boards used during Lora conferences, dating from 2017 so likely outdated information / status ?
Looks like there is still some misunderstanding as nodes connect to the network, not to a gateway. I know I’m picking nits, but these little details are what results in many hours of frustration when you get them wrong,
That’s right, there is not one use case either.
If you want something useful look for an LHT65, reports temperature and humidity at configurable intervals, indoor rated only. It’s a known good device if purchased with recent firmware (not 2 year and stock that has been gathering dust).
Make sure to get a unit for your region using the right frequencies.
The people there already have some experience with the device side (getting data to the network) and also with the backend side (getting your data out the other end). They may already have a gateway available, e.g. give you access to the live data of the gateway or lend you a TTIG.
If you get a board with an RN2483 chip, all of the device-side LoRaWAN stuff is handled by the chip, making things somewhat easier. Your device-side code only has to send high-level commands to the chip, and there are libraries for that. If you get a board with a bare LoRa chip (e.g. SX1272 or SX1262), like a heltec/ttgo ESP32 LoRa board, you need to configure / compile the LoRaWAN stack yourself, which is more of a challenge (but still doable).
