Hi,

received the device the other day and haven’t been able to update the firmware, too.
The App downloaded from Google-Play doesn’t even show the option to update the firmware, but it shows the build-version of the device.

The App downloaded from the given link in the box does include the option to update the firmware, but only gives the above already mentioned message “OAD not available on your BLE device.”. This App doesn’t show the build-version of the device, instead it shows the hardware adress.

Device is a Nexus 5 with Android 5 installed.
