This extensive video tutorial covers the technical specifications and practical applications of the RYLR 998, a blue chip equipped with a LoRa ultra-long-range modem, perfect for various hardware integrations including Raspberry Pi, Arduino, and ESP-32.

We'll walk you through the setup process using UART connections, GPIO pin configurations, and the necessary AT commands for device communication and network settings. Discover how to connect the chip to a range of devices using a USB to TTL converter, making it compatible with almost any USB-supported hardware. Learn the nuances of network IDs, address settings, and RF parameter adjustments to optimize your setup for maximum efficiency and minimal power consumption.

The video features detailed demonstrations of the chip's capabilities, including sending and receiving messages in extreme conditions and conducting a range test to validate its communication range and reliability. We also discuss the potential impacts of this technology on the smart device ecosystem and how it could revolutionize connectivity in remote or challenging environments.

Furthermore, explore potential safety applications for extreme hikers and outdoor adventurers, using the chip's technology to transmit critical environmental data and emergency communications, enhancing safety in wilderness settings.

By the end of this video, you'll have a thorough understanding of how to implement and utilize the RYLR 998 microchip in your projects, pushing the boundaries of what's possible with long-range, low-power communication technology. Whether you're a hobbyist looking to experiment with new tech or a professional seeking robust communication solutions, this guide offers the insights and practical advice needed to get started with LoRa and the RYLR 998.

LoRa is regulated by FCC as well (It’s just license free similar to the ISM band but you do have some limitations, which when exceeded means that you’re disobeying the law.
You don’t need a license to use a cordless phone as well).
By the way this regulation limits the number of messages that are allowed to be transmitted every hour by limiting the transmission duty cycle to between 0.1% and 1.0% per day depending on the channel.
Another note, it’s quite easy to triangulate such a device to find the transmitter so beware when you disobey the law.
Also you forgot to mention that the fastest transmissions speed for LoRa is 22Kbps (kilobit, not kilobyte) which will only work for short range communication (not much of a WiFi replacement lol).
In order to increase the range to the numbers you’ve talked about you have to reduce the speed to be 0.3kbps or slower.
At maximum speed at 1% duty cycle you’re limited by law and not allowed to transmit more than 2.376 megabytes per day.
There are less limitations on LoRa for HAMs in case the transmission is in one of the HAM bands (for example some LoRa chips use the 433Mhz band).
This case requires a license and has some other limitations.
For example encryption is not allowed as well as you’re required to transmit your call sign every time you start a transmission and every 10 minutes of transmission.

These are amazing little modules, easy to use with simple Serial control and insane range. Using decent tuned DIY antennas they easily make 11 miles LOS so far.

As a side note: no reason for the "wifi killer?" thumbnail thing, kinda clickbaity for something that is in no way at all related to wifi. That's like showing a picture of a Ford Focus with "Learjet killer?" You can't really run to the corner store in a Jet and you can't drive a Focus across an ocean, why pretend to compare them?

A cheap way to ping your lost pet and get a simple gps location returned without some kind of subscription would make a lot of people happy.

[AlexandreLefaure]

"You’ve Never Seen WiFi Like This" sure because this is not WiFi...

[LasseVågsætherKarlsen]

Heh, the "might not be up for long because industry giants prefer you not see this", that is usually the sign of a scam video or article.

[robertheinrich]

there is a swiss youtuber, who toys around with lorawan (european bands) and he tested it in alpine settings. connect to a known base station from a mountain, with a good antenna: maximum range 200km.
or in other words: the main problem is suddenly the earths curvature.
totally scary idea: what would be required for EME (moonbounce). regular moonbounce transmission require more than 100W sending power, way more than what lora specs allow. but since the requirements for a successful connection are lower too, a few watts might be sufficient.

[woahwoahweewah]

good intro... but for now what you said is just straight bullshit. LoRa is regulated to use different frequency in different part of the world, like 915MHz, 867MHz, 433MHz, and then there is the data rate, right now, LoRa theoretically top out at around 250kbps with 2.4GHz LoRa specification. You can't even watch your own video with that kind of bandwidth. You are misleading those people who don't have a strong background. In no world will LoRa replace WLAN. Then again, if your are already using 2.4GHz band, why not use Wifi then? It has way more bandwidth and crucially generally supported by most devices nowadays. If you would like to use on DIY project, why don't use a ESP32 then? It just as easy to use and it's way cheaper then LoRa modules.

You are a very smart guy and I did learn a lot from watching your other videos, but probably should have done more digging before making this video.

Yea i have not seen a wifi like this couse its lora duh

[GizmoFromPizmo]

I spent several years in the Industrial controls industry and the company I worked for made hardware and software peripheral devices for Programmable Logic Controllers of different vendors. Our serially connected devices used the computer's serial port (9-pin or 25-pin) and, although versatile it was bound by the slowness of the UART (pronounced "You-art"). (UART stands for Universal Asynchronous Receiver Transmitter). The data rate of the UART is known as the Baud Rate (pronounced "bod rate"). Nobody in the industry (and I spoke with a LOT of engineers and systems integrators) ever called it the "boud rate". It's baud, rhymes with "Maud".

[JorgeMen-yi]

"Wifi killer"??
I don't think so.
If you exceed the 0'1% duty cycle you can be fined a very-very-very expensive fine. (Up to 1 million euros.)
This technology is designed mainly for sensors and IOT devices. And I think it's awesome.

[allwayne]

Just an FYI, 'BAUD' rate would rhyme with Applaud, Maraud, Fraud, etc. It is not pronounced like it rhymes with Loud, Cloud, or Shroud. GREAT video though, well done.

"This microchip can send datas 12 miles away", no, it is not a "microchip", it ia module, composed of an MCU and a transceiver, none of which is made by the brand you affiliate, as a side note i find it funny enough these modules have the shape of a pigeon, it seems appropriate i would say.

[paratrooperlane]

I don't a have clue to what you are talking about, but I find it fascinating.

[davidrussell]

Back in 1960 I at 5 to 7 yrs old, was given a small device( radio) that you clamped onto a lampshade steel bracket( back when lampshades used a brass or steel shade bracket), or some peice of steel.it was able to pickup radio stations with no battery and worked on static electricity .
It had a volune control and staion changer, was the size of half a cigarette.

[brunodinis]

so.... a LoRa... thank you for the clickbait title

[newmonengineering]

I have a perfect idea for safety and lora. It would keep people safe. I think I will try to build one to test out. A simple esp32 or other microcontroller, a single sensor and an emergency call button is all that is needed to hike with, and a simple reciever tied to a cellphone as a base station would be able to make an emergency call if there is an issue. The hardest part is the what if sections of the code. But it would be a cool project

[johndoughto]

"traditional terminal like bash" - haha, was using AT commands via a "terminal" before linux was born in '91

Love this video... having flash backs to the 80's, with acoustic couplers and basic programming - just like your doing now!

this is amazing!

[JohnJones-oymd]

Once I heard him pronounce "baud" I started to doubt everything else that followed.

[parrotraiser]

How many people watching this immediately thought "Hayes modem commands"?

[foogod]

FYI, UART is generally considered an acronym, not an initialism. That means you pronounce it "yoo-ahrt" (like a word), not "yoo-ay-ahr-tee" (individual letters).
