Great presentation. Simple and easy to understand. One correction: Resistor divider should always be where Uno provides an output signal going to RYLR998 as input. In the case of the transmitter circuit you have it right but in the case of the receiver the 5v Tx signal from Uno is going unprotected to RYLR998 which is not correct. No resistor on LED for any extended period of time will burn out Uno. Briefly, might be ok but generally not a good practice.
My BBS days are long ago, My serial communication is rusty. But, I'm Excited to do this, If done right I could use Telnet stuff, or SSH. Man, so many projects, so little time. I'm pumped I will make this work.
Beautiful work, thank you so very much. Now it's my turn to make an interface between the PC and the Arduino board to serially x-fer files via UHF between boxes......
Hi am using software serial 2,3 as rx and tx. I am just trying to send simple sting message hi in a loop. but its only receiving hi only for a few times then stops it only receives more if i only restart the transmitter program. I uses the baud rate as 57600 as per your video
HI have been trying to get my lora modules working on Arduino for weeks, this is the first tutorial that explains setting up the LoRa BEFORE connecting the Uno. That's great and thank you BUT what is with hiding the code and circuit diagram in that bloody google drive that I can't open??? thanks for nothing. Another wasted effort- this stuff is the most frustrating thing in my life. Also all other projects with LEDs use 220ohm resistors why not here?
You have received +ERR=2 in the receiver part, so that means we cannot see what it is receiving in incomingstring.My question is how to get rid of this +ERR=2 error and see what data is coming from the sender?
He didn't set the bandwidth and spreak, I dont understand all that yet but that affects the power output and range. Look in the Reyax AT command setup.

Thanks for the feedback♥
I agree with your point, for continuous usage it is good to use resistor.
Thank you for a clear presentation on this subject. This is the first video that I was able to replicate your work using my RYLR998. Now I can play.
You're welcome!🙂

I have one doubt clarify ,is RYLR lora can communicate serially sending lora , mediate LORA , receiving LORA

in the circuit diagram you put resistors in between, but I can't find any resistors in the actual, how come?
Better to use resistors, the modules work with 3.3v.
Using for some time without resistor is fine.
Hi, Thanks for uploading this awesome project. Can we do same with Esp32 controller?
Yes
750m damn, i thought 10km !
This range we got in congested region. If open space it might reach very good range.

That little pig tail of an antenna is for shit.
If there any possibility to configure lora module without UART, maybe with arduino directly?
You can use Arduino uart pins to communicate with module. But it didn't work for me in the beginning.
