Then we could check the ones we receive and put this experience also in the above mentioned thread? Is there a chance to write si241r short arduino program to check the identity of the nrf chip used? Am I the only one missing references to earlier discussions in this subject? For example, operation at the ends of the ISM frequency band. Most purchases from business sellers are protected by the Consumer Contract Regulations which give you the right to cancel the purchase within 14 days after the day you receive the item.
Some circuits that are really si4r1 to that si24t1. My guess is that rather than using specific designs to specifications like the originals, the counterfeits just toss together pre-designed modules that get close enough to mostly work.
This applies to all radios being genuine or clones, si244r1 mixed? In this case, the most similar nrf24l01 clone is the SI24R01 data sheet available on baidubut there are others as well. Any experience using them? This item will be sent through the Global Shipping Programme and includes international tracking.
Nordic NRF24L01+ – Real vs Fake
This is my question as well. Postage cost can’t be calculated. So our nRF modules started out at “pasturized process cheese”, and now there’s “imitation pasturized process cheese food” entering the market – without such honest labeling.
In the US there used to be ” natural ” cheese, and “pasturized process ” cheese like “American cheese”, a sad thing to have named after your nation. I ei24r1 my sensors from e-Bay. Hi tekka, thanks again but result is always the same Got mine off Amazon, figure it would be safer then ebay….
si24r1 vs nrf24l01+ – working distance difference
Simple deep discharge protection for battery operated sensors? For additional information, see the Global Shipping Programme terms and conditions – opens in a new window or tab. Again, it’s going to tend to be measured via the visible registered from transmit fired to packet received.
Sl24r1 how your comment data is processed. Hi tekka, just for information: Of course I mean in the case of serious manufacturing, for some low cost low quantity stuff that might not be practical. Emailed my contact at Nordic about this a month ago.
Thanks for the warning. Have you tried other channels and locations and power supplies to rule out heavy interference or noise?
We are mostly using fake nRF24L01+’s, but worse fakes are emerging. | MySensors Forum
Report item – opens in a new window or tab. But the challenge of counterfeits is still a big issue. I wonder how else to test RF quality. If ACK’s are eliminated, then the timeout value could probably be driven much lower. So now I need to implement a random number generator on my PIC16F so that it starts with a different number on each boot up.
Let me start by saying that I do have a dog in this fight as I work for Nordic Semiconductor. I am a victim of those fake clones.
Sometimes these structures will be in the street between die and sometimes they will be drop-ins replacing several die in an array of x by y die.
Add to Watch list Watching. Hardware CRC checks can fail, and I’m assuming they were turned on by Mirf as a default definitely did. There are unfortunately little they can do about the problem.

On some other thread S2i4r1 gave a good argument for doing the tests without any ACK’s, and I believe he’s right.
Pooling our information should reveal who the good vendors are. After I receive the modules I ordered today, I’ll post which vendor I purchased them from, the price, and whether or not I think they’re ai24r1 i.

This is done for all or most devices used in that process, in various test conditions. Add to Watch list Watching Watch list is full.
And I mean on production sire, not just in an office in china.
