You can check out Serveral advanced projects like meshtastic, to get a real chat like experience

[@rohithg2975]

How we get that code

[@PeterNunnOZ]

Can you give us a hint as to where the repo went? I'm trying to set up exactly this at the moment and the code would be really helpful.

[@khushipandey6874]

Can we command quadcopter using LoRa , I mean rather then using RF can we use LoRa ?

[@MSMohdDali]

the github link can't be open. Pls provide another link.

[@debojitacharjee]

what will be the maximum communication range and is it possible to carry audio transmission?

[@mikesterling3949]

Thanks for the clear, powerful explanation. This is a "broadcast" sort of communication, isn't it ? Is it possible to do one-to-one communication with LoRa ? I mean, the sender decides who shall receive .... And the receiver only listens to "white-listed" senders ?

[@tobiashegemann1811]

P2P communication is possible with Lora and should have a higher usable bandwidth than LoraWAN, TTN or even a Lora meshes. But You would lose reliability and range because at least the receiver must use Class C Lora (Continues Listening) witch isn't great for power consumption.

thank you so much for such great videos you make.

Glad you like them!

[@mlit83]

Hey man! Greetings from Norway! I'm looking around for parts and ideas for a project of mine. I want to create a set of "walkie talkies" for my kids (boys 6 and 9). So some kind of IM device with an OLED screen and a tiny keyboard. Been thinking about using LoRa, ESP, or ZigBee, but yeah, .. u get the Idea? What would you suggest? I think 433 - 900MHz is good for penetrating walls etc, plus distance. Please let me know if you have any tips on how to get this happening, or if you know of some projects, please do tell! I'd like it to be like two small devices with a numpad (old phone keyboard) or a mini mini keyboard, a small 3-4 inch display and maybe a small speaker for incoming chat. Would you like to help me out?

[@CETech4u]

There's a video with title LoRa remote control on my channel. Check that out, you'll get some more ideas from there. Also you can email me if you require help! Thanks

[@Lokakyn]

Thanks for this video, it was very easy to follow and I have two working modules that are communicating successfully. I have two questions though: 1. I plan to use this with more than two similarly configured devices. Is there a way to make them broadcast as a unique name so when a device receives a message, it shows the sending devices "name" rather than "HIM:"? 2. Is there a way to interact with and program the RYLR LoRa module without having to disconnect it? I'd like to be able to configure it on the go, to change the network ID, address, and parameters from within the serial interface without having to disconnect it from the ESP module. Thanks for your time.

[@Lokakyn]

For anyone else wondering, I figured out how to command a default configuration for the LoRa module on startup, as well as sending a configurable name at the beginning of each message to identify the sending station. DM me if interested.

[@TecSanento]

For Your requirements you should Definitely Check out the meshtastic project

[@levicaaya5213]

any update abouit the github ?

[@SajalSirohiBIS]

Hi, you mentioned that these modules work on 890 Mhz band, but as per the indian standards LoRa can use only 865-867 Mhz band and also the 433 Mhz band because they are license free bands. I want to create a Lora network, but I dont think REYAX890 modules will comply with the rules set by theIndian regulatory bodies. Any suggestions on this? Thanks

[@CETech4u]

These modules from Reyax work in the licence free band i.e 865-867

[@vaibhavmali1841]

Can we use this without network ?

[@mananmodi1246]

Hey! I really liked your video but can you tell where i can get LORA RYLR896 Module in India?

[@kleetus92]

How did we go from 8kM to 600 M? Did you adjust the spreading factor at all?

[@CETech4u]

8km is for clear LoS and 600-800m is for urban area with many buildings for same spreading factor

[@dukenuke2690]

I dont quite understood what the ESP8266 was for ..?? are they connected to wifi ? COuld i also just use an USB to Serial adapter ?

[@CETech4u]

Yes you can

[@Bharghav861]

Why we are using esp8266 module here,why not other?

[@CETech4u]

Anything can be used

[@proudwing]

Hello sir, I was given a project that is a remote chatting program without internet connection. One of the specifications is using lora module.However,I'm not allowed to use any server.The package transfer must be done between end-to-end devices.So,I researched that how to do this but I found nothing.Could you please help me how to do this kinda transfer and project?

[@tobiashegemann1811]

There is a Lora mesh network called Meshtastic exactly for this porpoise kzbin.info/www/bejne/ioqZnmmciJ2Vrrc

Hi, good video, where can I get these modules please ? Also, how do you connect several devices, can they do a broadcast, can you set a name/address for each one ?

[@CETech4u]

Thanks, by default they work in broadcast manner. You can get the modules off Amazon, if unavailable in your region I can arrange them for you

[@TecSanento]

If you are looking for a more sophisticated version, check out the meshtastic project

[@LordGryllwotth]

Using bluetooth and a application on the phone would be nice, maybe even less power usage.

[@dankestporter]

Look up bridgefy app : it uses bluetooth to create mesh network for communication & if no one around uses wifi / cellular. I'm looking into building Raspberry Pi node boxes and then finding a way to add lora into this somehow.... because the app will run on "android things" on the Pi, so hypothetically it could communicate over Lora as well.

[@TecSanento]

Or as an alternative, the meshtastic creates a lost mesh network for wide spread networking and communication

[@polashchandramondal79]

what is the price of lora... that you use in video??
