Getting Started with LoRa | Tutorial

Today I'll take a look at these LoRa modules from REYAX, do a little bit of Javascript programming, and create a gateway that allows LoRa devices to interact with devices on BLE and WiFi networks.

/* LoRa Modules */

REYAX sells two modules that have different frequency ranges and different countries have different standards for those. For more information check out the links below.

For the US/EU these are the correct ones:

But your country might require these:

/* Espruino Boards */

I am just researching in this field
Thank you for your very clear explanation
Wonderful

I like how you explain what the code does. I can actually understand it. I have little to no experience using js, and I want top make a instant messaging device that uses lora then, i could give them to my friends for testing.,

This is exactly what I need to create some remote control devices . I want to create a suction cup cam operated button pusher. When I press the button it rotates a motor that has a cam love on it one time to press a button on an old manual machine. Do you think this would be a good way to do that?

[jackwinter]

Do you know of a way you replace the spring antenna with a better one?

Is it possible to let's say make a simple alarm with Lora.
But each contact or Infrared detector will communicate with the base station using Lora.
Then the base station communicates with the outside world using Lora.
As apposed to having each Lora device on the loraWan

I’m looking to build my own gps tracking device for small pets. My personal inspiration is in that I’m a falconer who doesn’t want to spend a couple grand on something as imprecise as radio telemetry. I’ve found an already assembled device, but it also requires a SIM and subscription. I’m totally willing to do that, but my interest is piqued by this vid and your gps vid. Do you have suggestions?

looking for 923 compatible with the standard selected for Australia.

R u using lora as P2P communication? Do you have video of lora wan devices?

[richardriordan]

I'd like to see how to add the LoRa module to the GPS you made in the other YouTube. I need to put something in my RC airplane to find it when it flies out of sight and is lost.

(I'm a bit late to the party)
And why haven't I subscribed before this? Actually I just stumbled upon your CH. Really GR8T line-by-line descriptions of the code. Now I've got that "I WANT ONE" urge (among my many urges, sorry for that visual). SUBBED & BELLED, who wouldn't? p.s. Project wise. Mine is most likely a physics problem. Can it be condensed into the size of a key fob? Ok, a fatty key fob. I realize that's more of a micro question. But I though I would get the ball rolling. Thanks so much.

i want to take information from a model satelite. But the model satelite will be 1km higher than groudn station. So how can i use that module. Also i want to calirfy that i am gonna use rasberry pi 0 as an processor. Thanks for helping and thanks for video

[desiarvela]

Amazing..
Please create lora and sand mulriple sensor

[dinhuxp]

Is possible make a broadcast voice? Like a voice conference, however, with many LoRas talking simultaneously. I'm having a project to make a type of phone that communicates at a "short distance", creating a group between them.

[iot-armywengineers]

Is it possible to connect multiple module to each other ???

[neilhodgson]

Hi Davy, good intro to the hardware I am impressed. Would it be possible to use this to transmit an image / text to a OLED screen or similar over distances of say 1KM? I am thinking of developing some sort of project that can allow me to have display modules on all 18 tees of a golf course which can receive an updated image with text from the clubhouse. The modules would be low voltage build into the tee markers. Using a LORA I heard that the same data can pass through each LORA onto the next creating an extended network? I do a bit of electronics but not sure if I could make this kind of project work or not? Perhaps you have some ideas.

[Gkmbile]

This would be great to have in my mailbox 200m away, to see if I receive mail.. (if the power consumption is low enough to run on battery over time?)

[farisrusydiirham]

Is it able to use LoRa without any WiFi connections?

[letsgettomillwithoutvids]

Could I make a lora long distance jammer by using a lora transmitter and sending random noise

[hanib]

Hi, can you make a video using Lora to send gps coordinates?!!
The power consumption is also important.

[lieric]

I am doing lora with communication with arduino and pi4, comminications has problem, could you help me pls?
