Raspberry pi pico nrf24l01 driver error

[UmutDemirel06]

Hi, I am trying to use the NRF24L01 module just to see how it works. I am using MicroPython to code, obviously, but I am encountering an error. Here is the error I am getting:

This is the code that I tried for testing:

https://github.com/tinkertechtrove/pico-pi-playing/blob/main/nrf24l01-spi/button.py

And this is where I got the library:

https://github.com/micropython/micropython-lib/tree/master/micropython/drivers/radio/nrf24l01

I am new to this hobby, and I just want the NRF module to work properly. Any kind of suggestion is welcome.

First guess would be something wrong with the wiring or the module. Can you describe (or post a photo) of how it's connected up?

Sure, but that doesn't help figure out what's wrong with your setup. Can you post a photo of yours?

Do you have a multimeter, can you check voltages etc on the nRF module?

[UmutDemirel06]

sure ı will do that as soon as ı can

I suggest you start with the official test script which has been tested on Picos. The code comments list the way to wire them up.

hi ı tried to do the test but

it's at this stage and ı don't know how to continue

[UmutDemirel06]

this is the wireing that ı did

Your wiring is wrong. For pin numbers you are using the board pin numbers but what you actually need are the GPIO Pin numbers. It's rare for board numbers and GPIO numbers to coincide. Consult the PICO pinout diagram for the correct pin allocations. They don't need to move far.

Also you have your 3.3v connection to the 3.3v EN pin not the 3.3v out pin on at least one of your boards.

Worth double checking module connections, it's impossible to see if they are correct from the photo.

I've tested the NRF24L901 board using the micropython-lib drivers and test program as suggested by Peter and it works as advertised with correctly connected pins.

ı am currently fixing the wiring thanks for your reply but ı dont know how to do the responder initiator thing can you help me with that

[UmutDemirel06]

ı finally ran the test but it's success=0 failure=16

[peterhinch]

Install nrf24l01test.py on both boards. Run

import nrf24l01test

on each board. It will print out the wiring that you should be using and will tell you how to run the test.

[UmutDemirel06]

it did tell me and ı fixed and checked the wiring but ı didnt under stand how to run initiator and responder thing

[peterhinch]

You run

>>> nrf24l01test.responder()

on one board, then

>>> nrf24l01test.initiator()

on the other.
