Nice work Antony! I'm very impressed with those modules!

Nice test. Impressive results.

Thank you. Just now i was able to transmit distance of 16.29 km or 10.1 miles

Very impressive distance!

Hello it was a nice tutorial and thank you for sharing knowledge. Kindly please share code and circuit diagram, will this module work through walls and trees?

It would be interesting to see a range test with spreading factor 11, and a thinner bandwidth than default 125khz. These two things from what I saw in videos are the things that provide the longest range. There seems to be some sweet spot to it.

Nice video, keep it up, thanks :)

Excellent

Hey this is the point to point connection lora example.. can you try these modules with any lora gateway? Btw, brilliant range from these modules!

Hi Antony, Great Video! BTW, Have you tested this module, indoor? If not, will you plan to test it indoor? Tnx.

Hello, I have a question for you about the reyax module, I'm working with lora for a project , I need to make lora multi-point nodes but your example is the point-to-point connection, my question is: if I use a reyax module as a gateway and other two diferents reyax modules as lora nodes ,they could send information at the same reyax gateway ? or they only function with point-to-point connection?

It is amazing!!!

What type of data rates can you get with these things? I can't find that specified anywhere. I'm looking at these for an autonomous vehicle project, but I'd need a few kilobaud at least. A few tens of kilobaud would be even better.

And this is achieved with the simple embedded wire antenna... Imagine the distance that little thing could do with a nice pair of yagi or patch antennas ? Insane!

Can we do a follow up video, please? I couldn't source this Reyax modules in the UK so I got a pair of Heltec LoRa v2, they work great and are the same chipset. They are unfortunately limited to peer to peer links without a LoRa gateway but these Reyax modules appear to be configurable to different addresses. They should lend themselves well to creating LoRa networks. Why not get a 3rd and show us how to network them? I have ordered some now but from the US and that will take a while. Thanks....

Ok, i bought two. if they work well, i'll guy a ton more. thanks for the video

is this a good choice for RC airplanes? I'm liking this idea.

Do they works in optimal directions? What will be range? Or they are only for line of sight? Please do answer

lol that bag looked soooo dodgy lucky cops didn't think it was a bomb lol

my result with AI Tinker RA-01 SX1278 Lora 433Mhz modules (very similar to yours and same copper antenna) while sending a "hello" with an increasing appended number was the following: the sender was going with me out of the apartment while the receiver printed out what it received and was sitting on a table, I made 20 meters going downstairs from a second floor, out of the stairs, an apartment with big bricked walls and a pair of apartments down to the street. Not that exciting but better than nothing, surely totally different result from line of sight transmission.

Very impressed by the range, I have ordered myself a pair. You have any project ideas in mind for these? Great video series, thanks!

nicely done, what about some range testing for urban environments?

Hi, could you do a part 4 to this series, showing how to modify your sketch to incorporate sensors, maybe a DHT22 ?

Hi, what would you recommend as transceiver module for 100-200 Meters distance? The RYLR890 seems to good for shorter distances and I am looking for something cheaper. Thank you

FYI... I just came across a similar Lora module called DRF1278DM.. Look it up on google

Did you manage to make a project with those module??

Should make a repeater with them and a solar cell and battery put a few out in the wild your distance would be pretty much unlimited up to how many repeaters you have. Could almost create some sort of "mesh network".

Many thx... Very helpful indeed A question.... I wonder how far you can transmit even when their is obstruction like buildings and mountains?

Hi Anthony, Nice test here, unfortunately you overlooked a few things that may land you in hot water... 915mhz is a licensed band in the UK and is used for mobile telephony, in the EU we should be using 868mhz LoRa transceivers to keep it legal. Also if you where using 868mhz transceivers you are also probably breaking the rules as there are duty cycle limitations in this band, transmitting every 1 second even with a 1 byte payload breaks this duty cycle. Anyway I would suggest looking at The Things Networking and LoRaWAN for your next experimentation, this offers internet connectivity for these devices on a community basis which looks promising.

Wow, I bet you could of gone around the bend and still had good signal. Maybe you could do another test and on the mobile unit add the oled display so you could see ping times. Instead of having the other unit just send, have the mobile send to the stationary unit, then that one would reply. Measure the time it took for the round trip. You could also send a longer message, like 64 bytes, and see if you get back the exact same message. Which means, another trio of videos ;)

Hi thanks for the video you could have used the Arduino Mini 3.3 volt that would make a good match but loved the video I think I will order two as I want to make a door sensor. Your links no longer work!!

As long as you have line of sight, you can go a long long way with radios.

What were your spread factor, bit rate, and bandwidth or were all of these left in default mode? Did you perform a comparison with the theoretical vs. field testing?

Hi Antony! Are they low power ? Can we use battery for a very long time ? Thanks. Marc.

Hello can this be used to track a stolen car ? what addiotnal parts would be needed and how much would it cost ?

LAP E01 voice transciver device.it uses LoRa.along with it which module here used?can you plz tell me

I want this to transmit a picture of the gate.

Nice test. Thanks. Lucky you didn't get the bomb squad involved. Bag of wires and blinking lights tied to a bridge?!?!

Is there any other transmitter and reciver i can use that is cheap and has a long range up to 200m?

Can u tell me your config? AT+PARAMETER Thanks..

I used it , but it's range is not more than 300 meters ! Did I do anything wrong ? or should I use an antenna ?

Can I use the module as both a receiver and a transmitter?

Where can I buy this ship? Can't find it on ebay

how many lora rf module we can connect at a time as master & slave ?

I thought the arduino was only needed for programming?

If I wanted to go to school to learn about transmiters and receivers, what would be the best place to enroll (in the U.S.).

can this work with helium miner ?

What spread factor and bandwidth are these modules using?

What about higher voltage.

Was there any loss of transmission rate?

Is 915 MHz allowed in Europe ????!!! By the way I really like and enjoy your tutorials. Thank you.

Hi Antony. Whats your at config? Thanks. Marc.

Hmm..how would someone react to seeing that at 4:32 a radioactive doggie poop bag or plastic bag filled with wires and flashing led tied to a bridge..I'm surprised someone didnt call 999 and the area evacuated 😮 I think you should have labeled the breadboards, are you sure you didnt take the transmitter with you by mistake ?

Probability -140db , -20 issr , non signal or non block on around.

Hi, I made skech on Arduino +HC12 it is "weather statdion" , one module send date ( DHT22 hum and temp), second receive and dispay on oled, if you want tell me, best regards, very good tourtial. Meaby you can check yours modul's with this one soft. Sorry - poor english

Any chance you can share your code? I am trying to figure out how to range test myself...

Obvio que esta distancia se cubrió configurando la potencia a 20dbi ¿O no?

4:37 do that in the states and you would get arrested on suspicion of terrorism ^_^ XD

Hi, Bro Where is the source code and the schematic. Kindly share it too...

Nice, but absolutely against laws..... if catched, it can be very expensive.

Stopped watching 3 minutes into the video because you didn’t get to the bloody point fast enough. Be concise.
