Feather M0 RFM95 upload sketch while in low power sleep

by michaelstranks on Sat Oct 16, 2021 11:52 am

I have a M0 with the RFM95 and I am using it as a field unit for collecting and sending data. I am using LowPower.sleep() to save power between transmissions, but when it is in low power mode, I cannot access it via the com port (Windows 10) it doesn't even show up in the list. Currently, the way it's set up, I have to leave the batter plugged in, so I can't technically even power it down. Is there some way I can factory reset it while still on battery power so that I can find it in the COM ports and upload a new sketch?

@michaelstranks,

When you want to upload a new sketch would you physically be near the controller where you can double tap the reset button to put it into bootloader mode and upload your sketch?
