Thanks Will. The 10mA is sort of what I'ver been reading. Was just poking to see if anyone had different numbers based on real experience and/or with mynewt specifically.
I'm specifically after the scenario were LoRa radio would be turned on to listen/receive for very short periods of time. I read on an Adafruit post that "The ~13mA quiescent current is the current draw for listening (~2mA) plus ~11mA for the microcontroller." That made me question if it'd be possible to bring LoRa power drain to only 2mA. source: https://learn.adafruit.com/adafruit-feather-32u4-radio-with-lora-radio-module/power-management Sent from Mailspring (https://link.getmailspring.com/link/[email protected]/0?redirect=https%3A%2F%2Fgetmailspring.com%3Fref%3Dclient&recipient=dev%40mynewt.apache.org), the best free email app for work On Nov 7 2017, at 1:14 am, will sanfilippo <[email protected]> wrote: > Marco: > > Not sure if you are referring to the current mynewt LoRa implementation or > LoRa in general.
