Hi,

There are unfortunately clones (fake devices) of the nRF24L01+ out there, especially the cheapest modules (< 10 USD per module), where the markings are cloned to look like a genuine nRF24L01+ device, and these do not meet the quality assurance that we provide.

We strongly recommend that you obtain devices from one of our listed distributors:

Kind regards,

I bought this module from a vendor. I am using wire antenna of 23mm length in place of PCB antenna (PCB antennna scratched from its feeding point ). Could you tell me the failures of this module?

Hi,

Is this a module that you have developed, or have you obtained it somewhere else? Could you upload a picture of the module?

Best regards,

Håkon

Yes, this issue occurs regardless of the range.

I have used NRF24L01+ and attached 23 mm wired antenna after removing PCB antenna also used 1pf cap at feeding point.

Not checked as written in Q3.

SPI frequency is 1MHz

Some times data is sent but ack doesn't come

Hi,

Q1: Does this issue occur regardless of the range between the two devices?

Q2: Which module are you using? Could you upload a picture of it?

Q3: Have you tried stripping down the application to only sending data on-air (ie: remove any application specific code, like ADC/I2C handling etc) and see if the 1/10 payloads are still misbehaving?

Q4: What SPI frequency are you operating on? Could you try limiting it to ~0.5 MHz?

Best regards,

Håkon
