NRF24L01+ - Not 250KBPS

[JeJ]

I recived 10 pcs of NRF24L01+ a few days ago but when i try them they only work on 1 or 2 MBPS.
When i run the Getting started sketch it tells me it's the + version.
Has anybody else had this problem?

@JeJ do you have + sign on the chip itself?

it is strange that it is not working on 250kbps while presenting itself as NRF24L01+

[JeJ]

Yes i have the + sign on the chip

@JeJ ok
all should work
may be some mistakes in a logic of your testing?

[JeJ]

If i plug in another "old" radio that i have it works perfectly!
It has to be something wrong with the new ones.
I bought then from the store on the Mysensors page.

AliExpress or Ebay?

Could you post a link to the product page from your purchase history?

That's the same ones I bought. First shipment was lost and 2nd shipment is supposedly on its way. They were good at resolving that, but hopefully these are legit chips and not some partially functioning clones. I should have mine in about a week from now and will test them for that. What's the best test procedure to confirm operation at the different speeds?

I got that exact batch of 10 from the same seller a couple of weeks ago. I did try one radio randomly and it did seem to work at 250kbps. Perhaps it is time to look at those radios again. Haven't really used them in a "production" unit.
