Hello,

Thank you very much for your explanation.

The solution is to call the functions :

• transportDisable() to put the radio in sleep mode
• transportReInitialise() to wake up the radio

I made the following test :

void loop() {
  delay(90);
  transportDisable();
  delay(60);
  transportReInitialise();
  sleep(30);
}

and verified the power consumption with an oscilloscope. I save 16mA, that is coherent with the rfm69 datasheet.
