I recently bought a Romeo BLE - Arduino Robot controller board V1.0 (SKU:DFR0305).

There is a button near the center-left with a label "BOOT" printed below (next to the pair-LED). Your WIKI describes it as "BLE Update Button". However I still do not know what its real objective is. I have searched your site but cannot find any further description.

I would appreciate if anyone can give me some idea. Many thanks in advance.
Hi thanks for your support.
This "BOOT" only used in updating Bluetooth firmware, you need not use in daily use.
Only when big bug occurs will we need to press Boot to update firmware.
