Gazell reception interrupt for nRF24LU1

[astella]

To the kind attention of Nordic support team,

I have got legacy code to work with for nRF24LU1. Radio packets payload and receiving pipe are retrieved using  if(gzll_rx_fifo_read(payload, &length, &receive_pipe)) instruction inside a super loop polling. I downloaded nRFgo SDK 2.3.0.10040 to search for an example where receiving interrupts are enabled. I like how this thing is handled like in nRF5_SDK_15.2.0_9412b96 for nRF52 new platform. For the new platform in new SDK void nrf_gzll_host_rx_data_ready(uint32_t pipe, nrf_gzll_host_rx_info_t rx_info) is called like a callback every time a radio packet has been received. My question: is there something like this for the old nRF24? Should be the case may you please point me to the right example o documentation so that I can enable rx interrupt for nRF24? Thanks for your attention and kindness.

Hi,

 

Unfortunately, the nRF24L implementation of gazell is designed around polling. There's certain aspects in 8051 that can be challenging, such as function pointers, as there's several RAM types in 8051, and handling memory overlaying can then be challenging. See this app note for more info:

Kind regards,
