Is this library still working?

[achapela]

I cannot make this library work anymore. On the receiving end, the "available" function always returns true, even if no signal is being received.

Is this library still working? Or is there another one that I could try out?
Please help.

Hello @achapela ,
Did you find a way to use this library?
I'm trying to use it to send/receive data on my Raspberry 2B but I have the same issue: the available function always return True =/
Thank you for your help

Yes. It´s working, I'm using in Raspberry PI 3 with Raspbian Jessy.

@Abi1506 Thank you for your answer :) I finally find another library to make it works.

@Gabedu2000 I use this one on my repo.
I just finished to create a readme file to explain steps to install it (with Python).
Don't hesitate to let me a comment if there are some mistake into my readme.

@achapela No, actually doesn't work.
Something changed in the Raspberry after an update.

Read this thread:
https://raspberrypi.stackexchange.com/questions/71730/possible-spi-issues-around-nrf24-operations-post-rpi-system-update

It´s necessary to add
self.spidev.max_speed_hz = 100000
in lib_nrf24.py

In the post say 4.000.000 but in my case I had to lower to 100.000 to make it works.

Thank you all for the help. I didn't make it work so I moved to another library. Cheers

@gcenjor Your fix worked thanks!

But your link no longer works here is the working link: https://raspberrypi.stackexchange.com/questions/71730/possible-spi-issues-around-nrf24-operations-post-rpi-system-update

Also for future referance you need to change in lib_nrf24.py in function:

def begin(self, csn_pin ... after self.spidev.open add:

self.spidev.max_speed_hz = 100000

@achapela thank you for opening this thread! I had exactly the same issue after an update to Raspbian Stretch and five minutes ago I finally managed to find this thread by the help of the "big G"
@fcanozkan and @gcenjor thank you for describing the solution - it works for me too.
You made my day!

This library no longer works on Buster and RPi 4. I've tried every possible combination of CE, CSN attachments and did the "self.spidev.max_speed_hz = " hack in lib_nrf24.py using various values. Can't seem to get it to talk to the radio. Also tried several different radios. Also - I have to radios humming away on two different arduinos sitting next to it so I know there is valid data being transmitted. Any additional help is very welcome!

using the hack
self.spidev.max_speed_hz = 100000

I can confirm that it worked in a raspberry pi zero w

somehow I needed to do a reboot after multiple tries and it works

I confirm what @markandkymward mentioned:

Despite numerous attempt I can not make it work on a raspberryPi4. The Pi refuse to send data. Also down same test with 2 Arduino and the rf24 transmitter/receiver are working fine.

Will check if other library make it work but for the moment I am stuck. Any help you may have would be appreciated
