Absolutely wonderful video, I am not lying when I say no other TH-camr could explain the module this well and get straight to the point... thanks, you've got a ney sub!
thanks mate!
Couldn’t agree more!
In stead of the brake-out board, you could consider using RfNano, that's an Arduino Nano+nrf24l01 in one. Maybe distance could be an issue, but I have good experience with RfNano.
This is exactly what I am looking for. Thanks a lot Sir.
Nice explanation . I have implemented without any problems.thank you sir...
Awesome I got your channel from your Coil gun
00:04 NRF24L01 for long-distance communication
00:46 NRF24L01 is a versatile and powerful wireless transceiver module.
01:23 NRF24L01 module is simple and best for small, cheap and short-range communication.
02:23 NRF24L01 comes in single and multiple pieces with different ranges
02:56 Understanding the wiring diagram for the transmitter setup.
03:48 Setting up transmitter and receiver for message transmission
04:24 Power the receiver externally and connect it to the transmitter and computer.
04:54 NRF24L01 eliminates the need for rewiring devices.
Thanks buddy for this video, it will be help me.
hello, I have a device that has an NRF24L01 in it, can I put the NRF24L01 PA/LNA to increase the signal range, will it work immediately or will I have to make settings, please tell me
i have 2 x rfx2402e module from wltoys v666-ufo, but i try with nrf library not working, is there any other library?
This was extremely helpful. Thank you so much. I understood your accent and everything. No offence intended just some smaller channel youtubers have very thick accents that are hard to understand. Anyway Thank You so much.
Glad it was helpful!
Tnx Arnov...That was to the point and very informative...can you post some test outdoors for this unit please?
Thanks! Will try to make a part 2 of this video in which some outdoor testing will be included.
Nice! 👌
Tahks you are very good
sir watt we can connect nrf240l transistor with the flysky ct6b receiver please give me replying please😢😊
Can an nrf24l01 can connect to an RF nano?
Is nrf adapter necessary to use with these nrf modules ?
Not really
Using nrf24l01 antenna module, i successfully get renge more then 700meters in open area. It's funny depending on power system and good connection! I had designed dadicated pcb for it I got 700meters...
Which one you use PA/LNA or the other one
@@ayanmukherjee4531 pa+lna module
Bro that's a qualityful content but plz can you tell me that what is the minimum range in the nrf24l01 antenna version in a heavily crowded area?
That depends on obstruction between sender and receiver. If there's whole building in between then maybe less than 100m. Even 50m
@@ArnovSharma ohh damn now this is really poor range
Here's one solution, add an antenna to this module. You can solder an external antenna cable directly with the nrf pcb antenna
@@ArnovSharma nah bro I said the nrf24l01 PA/LNA version not the PCB one what will be the range of that will be in a crowded area

Can someone help me with the Library required?
Maybe link?
Hello after working with these modules. I finally got it to work from your video THANK YOU. however, i have one problem. it will only send the signal a random amount of times then stop. I must then restart everything and it will again send a random amount of text's then stop. any idea what might be causing this
Baud rate perhaps
analog gaming controller?
Can you share the PCD design Files ?
how many meters it can communicate within building with multiple walls between TX and rx.will it communicate with person outside building
around 80-100 meters
please do range test for NRF24L01 PA/LNA in open and closed space
In close space, its around 50 meters and in open its 200 meters
@@ArnovSharma how many meters it can communicate within building with multiple walls between TX and rx.will it communicate with person outside building
why my serial monitor not appear?
I successfully use pushbutton to control LED wirelessly through this module but never with Servo. I don't know why.
please help.
its basically the same man, you should check my other video on this servo controlling topic. I prepared a transmitter and receiver setup for toggling LEDs, servos, ESC.
@@ArnovSharma Can't find the video about Servo that you mentioned. Here's the code. I don't know the problem which cause my UNO not responding to

nrf24l01 modules without antena is not 300 meters is maximum 50 meters open land
Thanks
Hey, where did u buy these modules?
Amazon
Need to make a wire less subwoofer, if you can prepare, i will pay the payment
Super sir for 10 km range which RF module is best
LORA MODULE
@@ArnovSharma sir lora ke bhi bhut projects dekhe but koi mila nhi open area me to chances h but building se nhi
Lora se 6 km range tak cover ho jati hai Bhai.. bass thoda mehnga hai Lora.
@@ArnovSharma ok bhai
Can we buy these modules directly from nordic semiconductor as half the modules in market are fake
Use Nordic official distributors, like arrow, mouser etc
Can u suggest me what is the cost of this module
In india 350rs -450rs max
Can you see this beacon on Android bluetooth scan by just powering up the module?? I mean without connecting it to a arduino???
What beacon
@@ArnovSharma I mean once you power up NRF24L01 will it show in bluetooth list even when not connected to arduino
@@razorr1920 didn't knew that. I guess because they both work on similar RF frequencies?
Can this receiver model work under water means receiver model can catch signal underwater
It can but you need to waterproof your setup by potting it in epoxy or similar stuff
Thank you sir
Can we use nrf 24l01 module to usb printer to make it wirelessly and send prints from mobile wifi and laptop wifi plz help me
Nice Project idea, it seems possible but why not use ESP32 instead of the NRF?
from where can i install the nrf24lo1 library
I also need it.if you have please share the link
hy, I dont know why, my nrf modules are not working anyhow. i have tried many methods but still not worked. can you or anyone help me out please.
May be there is a problem in the circuit , you can heat the pcb and try.
How many distance got by real time testing
Full coverage inside House and 200 m outside
@@ArnovSharma I ordered 10 pieces of normal nrf24l01 modules for my future projects..... If the range is too short it will be a waste ...... so thank you ✌️❤️
@@dov9528 you can increase the range by connecting them in a mesh system like one module will send data, the other will receive and then send it to another module, and so on.
Can I use that tool for WiFi repeater, pls pen
you can
Bro can we use it as wifi module
Nope
@@ArnovSharma tq bro
Hundred metre kaise hoga 1000 m hoga 1.2 km
Can nrf24L01 pa/lna communicate with nrf24L01?
It can. Just use same address for communication
@@ArnovSharma thanks arnov but what will be the range 100m or 1km?
@@Rehan-ru9ux 200-300m, for 1km use pa/ln module
@@ArnovSharma sir i mean to say what will be the range if we use one pa+lna and other nrf24l01 ?will it still be 200m?
@@Rehan-ru9ux it will be 200m because you are still using the smaller range version. PA LNA module can transmit at 1000m but the generic NRF24L01 cannot receive the data from the 1000 range.
Why my nrf24l01 not connected each other please reply the solution
have you added the capacitors to VCC and GND? if yes then try to reset both TX and RX setup at same time
Please reply how to reset tx and rx please send tutorial
