Feather 32U4 LoRa always enters bootloader after reset

Post by map_93 »

Hello everybody,
I am using a Feather 32u4 with lora module.
Whenever I press the reset button (1 quick press) the board enters the bootloader mode for 10 seconds, then it resets and starts the sketch. The same happens when I press the reset button twice in quick sequence.
I though the board would enter the bootloader mode only with the double tap of the reset button. Waiting for 10 seconds every time before the program is executed is a bit of a problem for me.
Does anybody have any suggestions on how to avoid this problem?
Thanks a lot for the help!

One quick press should just be a reboot and two presses to enter bootloader according to the docs.

What code are you running on it? If you upload a basic blink program do you see the same behavior?

Hi mikeysklar,
Thanks for the reply.
No matter what sketch I run, the behaviour is the same. I tried with my sketch, the blink sketch, an empty one too.
Any ideas?

I have a Feather 32u4 Bluefruit which goes into bootloader mode on single or double reset press. I see the fading red LED next to the USB micro-B port pulse for 10 seconds with either press.

I'll ask engineering about the discrepancy with the documentation.

Hi,
Same exact behaviour I am observing. I have 4 different boards (same Feather 32u4 LoRa model) and they all do the same.
Thanks for asking the engineering team, let's hope they have a solution.
