I'm coming here from the device recovery page because after a dozen recovery attempts, my Feather is still acting weird. Before this incident, I had it working well. I was able to connect to it and echo characters sent to it, and I implemented a heartbeat signal that was working as expected.
The problem started when I uploaded a sketch in which I was trying to read UART messages that would trigger LEDs patterns using the FastLED library. When I uploaded the sketch, the Feather became non-functional would no longer stay connected to my computer for very long, much less send the heartbeat signal. I could still connect to it from the BluefruitConnect app, but no more heartbeat signal in the UART interface. After going through all of the DFU stuff on the recovery page with no luck, I was able to get the Blink sketch to run by double-clicking the reset button while uploading.
But now I have another problem. I have uploaded the "feathertester" example app, and this is my Serial output:

Have I bricked my Feather? If so, how?
