this is a nice video. please tell how to use & how many ways we can use DIO1-5 pins. please suggest a module to communicate 5-6km, point to point communication and half/full duplex, in india, if u make a project on this that would be great.
Thanks! A note: The Ra-02 says 410-525Mhz, so I guess that is configurable (?). Do you know how to hook it up to a programmer and program it directly? It does not seem to be 5v tolerant by the way :)
can you make that module serial write date time that would last for a period of a month with a repeating signal that turns on every 1/2 hour to geo cache items in a geo cache hunt game? Can you show me how to do that I think that would be really cool and it adds a new twist to geo caching..
Sir i need confirmation between sender and receiver in lora 02 with atmega328 that the front has received the message.So no need to send the message now.is it possible
Hi great video really appreciate. I'm trying to use REYAX module and I'm blocked because I didn't found how to send a variable like temperature or humidity with the AT comman AT+SEND .Can you please be so kind and send me some ideas how to do it .Rgds
can someone help here im using an ra 02 ai thinker sx1278 433 mhzim trying to send packets then sensor data dht using an arduino well the problem here i want my signal to be in lora mode means css modulation but without succes s i tried using the registres in my programme but without success so if any one here used that module please give a damn programme who sends packets in css modulation why i want that because i want to decode the lora packet with gr lora project that uses css modulation so please please help ?
Please Help Yesterday I bought pair of RA-02, I have created my own breakout board for the project (DIY) . I am using one of the RA-02 with Node MCU and the other one with Mini Node MCU. I am sending Packets but it is not received by the other Module. Please Help me. I am using the same code of yours @CETech
you are wrong. The RFM96 is for 433 and 470 MHZ, not for 868 MHZ. The RFM97 is for 868, not for 433 MHZ. Read it here: www.digikey.com/en/datasheets/rf-solutions/rf-solutions-rfm95_96_97_98w
Very well explained and your hand drawings make the explanation easier to grasp than an animated or digital presentation. Thank you sir.
Well made video! Really helpful that you show of the differences between those modules.
Quite informative! and Yes Sir I do want to see Lora project using RFM98 !
Outstanding information. I found it extremely informative and helpful. Keep up your great videos. 👍👍👍
This is an intellectual generosity.. Thanks...

Do you have a video showing the SPI implementation of the two cheaper module? vs the UART of the Reyax RYLR993
Excellent Video. Very Detailed. Thanks.❤👍
RFM 95 is 868 Mhz , will it work in india for 865-867 Mhz then how to change frequency of modules
Great video. Very informative. Thank you.
Excelente video, cual tiene mayor alcance en mismas frecuencias? o cual frecuencia tiene mayor alcance?
Thanks! A note: The Ra-02 says 410-525Mhz, so I guess that is configurable (?). Do you know how to hook it up to a programmer and program it directly? It does not seem to be 5v tolerant by the way :)
can i run lora-02 on a frequency other than 433 , like 440Mhz or 450Mhz?
Okay you earned a subscriber
Thanks!
is it possible to make a mesh network with the LoRa Ra-02 module or with RFM 95
Great video CRTech. I wonder how can I make a LoRa gateway with those modules
How many transmitter lora node can communicate with single lora reciver
Can we make 3dr radio telemetry using this module?

How to access DIO1-DIO5? Thanks
What is the communication distance of all modules?
Sir i need confirmation between sender and receiver in lora 02 with atmega328 that the front has received the message.So no need to send the message now.is it possible
Hi, what are highest supported ranges by each modules?
ARE THESE MODULES ARE LICENSE FREE FOR OUTDOOR WORKS
what is the communication range of hopeRF devices, thank you
is it hope rf RFM98 works with radio head library??
can i use directly RFM95 library on RFM98??
Hi great video really appreciate. I'm trying to use REYAX module and I'm blocked because I didn't found how to send a variable like temperature or humidity with the AT comman AT+SEND .Can you please be so kind and send me some ideas how to do it .Rgds
Can I use the RFM95W module to work with the AU915 ISM band which is 915 - 928 MHz?
You have to set the correct frequency in the code
Can you give idea how can i transmit video data over lora. I want to build my own video transmitter for long range but didn't find anything
Video on that coming this weekend! Subscribe to stay notified...
Made me to learn more about it tq 👨
Fantastic Video!

are RFM95 and RFM97 compatible for transmission of audio signals?
yes pls...reply
Nope. Not used for audio signals
Sir,
What is transmission range of RFM95?
can RFM95 and RFM97 transmit of audio signals??
Nope. They are used for low bit rate signals
can we use RFM95 for transmission of current and voltage values
Yes you can
Great 👍 explanation!
Which one of rfm and ra-02 best for range?
I think can't be more then 2km
Similar range
Please Help
Yesterday I bought pair of RA-02, I have created my own breakout board for the project (DIY) . I am using one of the RA-02 with Node MCU and the other one with Mini Node MCU.
I am sending Packets but it is not received by the other Module. Please Help me.
I am using the same code of yours @CETech
heii me too
you should not connect the 5V arduino SPI to the 3.3V rfm95 directly btw...
Is any simulation software available for circuits containing lora? Thank you.
Nope, haven't come across one
According to datasheet RFM96 is of 433~470MHz, i guess you mistakenly wrote it of 868~915MHz.
Bhai ek video rc adrino transmitter for bluetooth deivce
can we downgrade oi frequency 865 or 867 bcoz this are licence free in India
Yes. Those are the frequency bands we need to use in India
can we user reyax R896 in India at 865Mhz or 867Mhz ?
Yes
any low cost lora for india bands
Yes RFM boards are legal in india and low cost too
Very helpfull. Thank you
Can I used Ra-02 in india? plz help guys
Yes
hello sir. As par my knowledge 433MHz is not used for commercial purposes.
Very informative
you are wrong. The RFM96 is for 433 and 470 MHZ, not for 868 MHZ. The RFM97 is for 868, not for 433 MHZ. Read it here: www.digikey.com/en/datasheets/rf-solutions/rf-solutions-rfm95_96_97_98w
Thank you!
It would be great if you could make a version in English! Or add subtitles.
What are you on about? It certainly is in English, and there is subtitles
