it displays junk in the serial monitor
Set the Serial Monitor speed to 57600 as written in the setup
Syed,
Excellent write-up on interfacing the Arduino with the NRF24. I've been researching this for some time and found your explanation simplest to follw. One question: How would the transmit and receiver sketches change if I want to use all 6 pipes. Basically having 1 byte of data sent from 6 individual Arduinos to the central Arduino?
I want to send two unsigned long variables, what do I have to edit in the sketch to make it work, can you explain also this part :
typedef enum { role_ping_out = 1, role_pong_back } role_e;
const char* role_friendly_name[] = { "invalid", "Ping out", "Pong back"};
role_e role = role_pong_back;
great, its working.
i want to add a button to the transmitter side.and put led to the receiver side.when i press the button then led should turn on.
what editing do i need in this code?
Hello, I have tried many times to get these chips talking without success .This is a very clear and easy to understand tutorial .Well done. The downside is i am like one of the other commentors getting just a series of numbers in the serial monitor eg.4294967295 what is wrong? its so simple ,I am getting no errors and the baud rate is correct.I have double checked all connections.
can i transmitte GPS data through this from TX to Rx side.
Hello Sir,
I need the NRF24L01 library for Proteus and I didn't find it nowhere.
May you please help me and show me any link to download it?
Thanks in advance!
hello, your above article was really helpful for the start up. i have this doubt, if nrf24l01 can be use to communicate with android. if possible, please do brief on it.
Hi there! I did everything that you said step by step and my transmitter isn't transmitting and my receiver isn't showing a thing on the serial monitor... its just blank! I really need an advice guys :D
hello zain
my nrf24 stoped working,
I am wobdring what is the probleme ?
what gonna happen if I Source them by 5v instead of 3.3v? would they have been burned ?
the same question if i basculate the ground with 3.3v?
I have nrf and nrf + antenne
Yeah they could be damaged if you don't provide power supply correctly. So, I would suggest you to first check the default example and test your NRF chips.
hello, how do i interface two arduino to communicate to pc using nrf 24? this mean that my two arduino are both tx and pc is the Rx
thank you
same here
since you dont get a reply i was wondering if u got your project working..
if so what did u do?
i'm stucked.. have some things to try yet but cant figure out exactly what is happening
I'm stuck and need help!
all blank in my serial monitors
using a robocore arduino uno
and a arduino mega
radio(9,10) on uno
radio(9,53) on mega
doublecked all the connections
tried the capacitor solution with a 70uF
still nothing
help anyone?
It works! Thanks for the tutorial! Upon testing I have noticed that the signal is weak. The connection is lost when I move the transmitter one wall apart or 1 floor apart from the receiver. Is it the same with yours?
I am recieving 0 on the serial monitor and somr random number in the middle like 234785. I am not able to get the problem.Please let me know what is the solution for this.
have you got it?
I need that too!
Hola, me funciona muy bien, que tendria que hacer para usar un servo,
muchas gracias
Hello, it works very well, I would have to do to use a servo,
thank you very much
i got the same problem
You need to place a capacitor of 100uF between +3.3V and GND of nRf24L01. For more details, read this tutorial: https://www.theengineeringprojects.com/2015/10/nrf24l01-arduino-response-timed.html
Hi I've copied the program correctly and installed everything like the video but it does not send the number one but it sends random typing what is the solution
