irq pin for nrf24l01

ok, thanks. What MY_RX_MESSAGE_BUFFER_FEATURE actually do ? what are the cons nad pros in the context of the repeater node ?

What MY_RX_MESSAGE_BUFFER_FEATURE actually do?
The nrf24 radios can only buffer 3 incoming messages at most, if more come in they will be lost.
For repeaters and gateway (basically non-sleeping sensors) this feature enables immediate retrieval of incoming messages and buffering in internal ram. For crowded networks, or sensors which send a lot of data at once, this feature reduces packet loss.
Drawbacks are the increased use of ram (amount of messages buffered can be configured) and the nrf irq has to be connected. -

el free to update th
"NRF24L01+ & ESP8266" section should be also updated ?

understand, but now i'm designing the device which hopefully will run for couple of years, so sooner or later this irq pin wiil be necessary.
-
so if i use an esp8266 as gateway AND i want to use the bufferfeature - to which pin do i have to actually connect the irq on the esp8266? The documentation is not helping me here.

ESP8266 does not support message queuing, sorry.
