Hi there
I purchased an nRF52840dk to aid in debugging my device. I am using Arduino with the Bluefruit BLE library. PIO Core 6.1.14, VSCode on Windows.
When I use PlatformIO to upload, it erases the device and uploads the application but not the Bootloader. If I Burn the bootloader first then select Upload, same thing. If I Burn the bootloader then try Debug with upload, same thing.
I have checked the memory map layout via the nrf programmer app to confirm that the bootloader is missing.
Any suggestions?
