BleuIO continues to release firmware versions and adds new features regularly. Therefore, it is important to keep the dongle updated.

BleuIO users were able to update the dongle from Windows and Linux system. This new updater allows updating the dongle from Mac as well.

The BleuIO comes with a bootloader to allow us to update the firmware or flash our own application to the dongle. To flash the dongle we will need an image file containing the new firmware or our own application and the updater script.
