Is there any nrf24LU software demo?

[SevenZeng]

Hi all,

I want to make a 2.4g wireless keypad usb reciever application, I tried to found some offical software demo but get nothing, is there such demo supplied officially? Or how can I get it from anywhere?

Many thanks

Hi,

There are two options, either the nRF24LU1+ (old chip, no software updates for several years) or nRF52840 (new chip, supports also BLE)

For the nRF24LU1+ you need to check out nRFgo SDK v2.3: https://www.nordicsemi.com/Products/Low-power-short-range-wireless/nRF24-series 

For the nRF52840 you need to check out nRF5 SDK v15.2: https://www.nordicsemi.com/Software-and-Tools/Software/nRF5-SDK 
(Examples: https://www.nordicsemi.com/DocLib/Content/SDK_Doc/nRF5_SDK/v15-2-0/examples_usb) 

Best regards,
Kenneth

Hi Kenneth,

Thanks for your help. I've downloaded the code I'm looking for.

I have a further question after reading some of the docs recently which is bothering me: What's the relationship between Gazell and ESB? Seems they can both accomplish the wireless communication, and use the same radio peripheral,  but what's the different between them?

According to my understanding, the lifetime of the nrf24LU product which has a USB controller is ending, is there any nrf product that is compatible with this one which has an USB controller as well?

Many thanks!

Hi,

GZLL is based on ESB.

ESB handles auto-ACKing under-the-hood, and it communicates on a static RF channel (no hopping). 

GZLL has a top layer, which also includes frequency hopping/frequency agility to ensure a stable RF link.

You may consider the nRF52840 instead of nRF24LU1, however there is no plan to obsolete the nRF24LU1. In general check out: https://www.nordicsemi.com/-/media/Investor-Relations-and-QA/QA-reports-and-certificates/GAN00111pdf20160215120205nRFseriesLongtermPartsAva.pdf
