Hi Yveaux, many thanks for your effort to my case.
I didn't knew that after a wakeup, nrf24 is in stby before the next restart loop.
Indeed, I tried a new sketch and confirm this particularity.
So, a workaround should be to put a "sleep()" at start of the "loop"
void loop()
{
// => At this point NRF is in RX mode
sleep(xxx ms); // Put NRF24 in stby
// ******
//
// All job here without NRF consumption !!
//
// *****
} // End of loop
I will do something like that !!
Maybe, a new definition should be interresting, like MY_NRF24_RXMODE_DISABLED
I'm sure many nodes never need the RX mode.
PS: Hum.. !! I didn't tried if after the send command, NRF24 come back in RX mode or not.
