NRF24L01 Getting Started Guide 

thanks mate!

Couldn’t agree more!

Thanks

Glad it was helpful!

Which one you use PA/LNA or the other one

@@ayanmukherjee4531 pa+lna module

Thanks! Will try to make a part 2 of this video in which some outdoor testing will be included.

Use Nordic official distributors, like arrow, mouser etc

Can u suggest me what is the cost of this module

In india 350rs -450rs max

Nice Project idea, it seems possible but why not use ESP32 instead of the NRF?

It can but you need to waterproof your setup by potting it in epoxy or similar stuff

Thank you sir

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.

Not really

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.

May be there is a problem in the circuit , you can heat the pcb and try.

around 80-100 meters

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

you can

Baud rate perhaps

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?

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

How to reset nrf24l01????

Nrf24l01 not working what I do ?reply

@@be8d973 Try to Reset both Transmitter and Reciever at the same time!

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

I also need it.if you have please share the link

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

@@tahasinmohammadtahasin9300 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...

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.

LIFE JOOOS

Nope

@@ArnovSharma tq bro

How about making an two way communicator with lora module. Like a walkie talkie for 10k range.

@@ArnovSharma device ON OFF with feedback possible or not sir

@@dassajityadav5555 possible

Thanks !
