Before you connect a USB cable to this device you must REMOVE BATTERY !
This important info is missing from the getting started document, but you’ll
find it on the shop’s webpage :thinking:

also its even better to remove the PCB from the backplate, because if not, you can’t press the reset button.

OK… what firmware/bootloader is installed then on this device ? I don’t know
I allready disconnected the battery and connected the micro usb cable.

first I checked win 10 devices and (in my case) updated the Silicon Labs 210X driver
to make sure my USB-serial is working

my first attempts to ‘talk’ to the device failed :sunglasses:
