On a side note, I’ve seen a strange behavior when using Reset.
As stated on Adafruit Feather 32u4 Lora thread, a reset put you in “Bootloader Mode”.
I did some testings with the same LoRa OTA Sketch.
It’s working fine either before or after a reset. There is a power consumption difference in deep-sleep though :
- First boot : Around 170µA
- After a reset : Around 230µA
I guess Bootloader mode forces USB to Serial on… Forever.
PS: To make a “normal” reboot, you can short EN pin
