Feather M0 RFM69 sleep mode

by johnlavik on Thu Jan 21, 2021 1:19 pm

Can you give me any references on how to invoke sleep mode on the Feather M0 RFM69? Is there a difference between the radio chip sleep mode and M0 sleep mode? Can I use interrupts to wake from sleep mode?

Are you using CircuitPython or Arduino?

For Arduino:

radio.sleep();
radio.setPowerLevel(0);

We also recommend this library has two deepsleep examples.

i use radio.sleep to power down the radio and additional RTC.Zero to power down the rest of the board. The SAMD21 has a internal 48kbit oscillator and a external 32kbit oscillator. The external oscillator give you the change to set a RTC and trigger a wakeup along the external clock.
