Flashing with a pkg.zip

• Download the release zip: https://github.com/larsgk/web-nrf52-dongle/releases

• Put the device into bootloader mode by pressing the teeny tiny button on the side of the component next to the obvious button (near the N logo in Nordic). It will flash red

• Find the device address, look for the odd one out:

ls -lha /dev/tty*

• Flash the device:

nrfutil dfu serial -pkg pkg.zip -p /dev/tty.usbmodemE12DB15768271
