Thanks for that clarification. I did upgrade the firmware file on my LabRadar SD card. But my Samsung Galaxy S21 still won't bluetooth connect to LabRadar. This seems to be problematic for some Samsung smart phones, and not so much with iPhones, from what I've read and gather...
But Samsung tablets seem to bluetooth connect to Labradar just fine.
