Hello,
After flashing a sketch everything works fine. The issue I have is after powering down and the powering up, the nRF52832 goes directly into DFU mode. I suppose there my be something in the sdk_config.h file that is causing this to occur. I am using Arduino 1.8.15.
Any insight will be appreciated.
Craig H.
This occurs even when Basic Blink is flashed.

Craig,
Is there anything else connected to the controller? Do you see the same behavior when the power supply is USB connected to a PC versus a USB wall plug?
Which bootloader are you running?

And the bootloader version you are on?

I've located feather_nrf52832_bootloader-0.6.1_s132_6.1.1.zip
I don't see how to flash it to my board.

@craighoffman,
You can flash the bootloader to your board using the Arduino IDE or via command line utility adafruit-nrfutil. You can use the same link I provided last time for instructions.
https://learn.adafruit.com/bluefruit-nr ... bootloader
Be sure to unzip the downloaded file. There is another zip within that zip that is your bootloader to upload. Confusing, I know.

I am starting with a double reset to get the PYGAMERBOOT mounted.
Dragged that file onto the drive, GREEN lights changed to all whitish purple\?
The screen remains dark.

Craig,
How did we got from updating the bootloader on a nRF52832 device to the PYGAMER bootloader update?
