hello,

H have a NRF24L01+ module that don't reply on MISO pin ,

and the CSN pin is High all of the time,

Is it malfunction ? and will not work?

How I can test it?

Hi,

 

Maybe it would be better if you ask this qustion in the Nordic Devzone.

 

Regards,

Moe

Many of the so called nrf24 modules don’t have a real Nordic device.

How can you test it? Run the Arduino examples. At least you can be reasonably sure the code will work.

Kartman...there is Laird...Rigado..and many else. while they are not called purely nRFxxxx, its based on the nordic modules, so inside there is the nordic modules which is compatible with the pin numbers. Its easier to use one of those Laird or Rigados BMD-330, BMD-340 because mainly the certification is easier for the RF and so on.

 

EDIT: typos

It may be easier to go buy something else, but it's quite possible the OP does not have that luxury. Kartman provided a very good answer on how to test the OP's hardware as per the request.

@Jim: I was refering/commenting on the first part of Kartmans comments , would you like to add something ?

Moe, whilst you may purchase brand name modules, the likes of Alibaba et al can get you some very cheap ones........

I wonder if the OP has a 'real' nrf24 or not so kosher one? I know where I'd lay my bet.....

If the CSN pin is always high, your counterfeit NRF will never output. It only pays attention to SPI when CSN is low.

 

The counterfeit parts contain an NRF compatible chip, which would be perfectly fine if they were not fraudulently labeled NORDIC.

Not at all.  It is commonplace here to simply tell the OP to go buy BrandX, or BrandY etc. and throw away what they have.  My comment was for everyone to simply remember that this may not be feasible for the OP.  It is not directed at one person specifically.  And the OP did ask:

To which Kartman provided an appropriate response.

 

Cheers,

A while back I did some work and concluded that the clones were notoriously bad. In my case I was able to check the registers against an authentic nRF24L01+ and compared it to a suspected clone.

 

 

The same code was used to print out the registers. The image on the left is a true authentic chip. Now there is no way to prove my theory, but the suspected clones had epoxy over the chip. The Authentic ones that I got from an authorized dealer did not. So you be thew judge.
