FAQs on mBot Mega - Software

1. I can't use the default functions (gesture recognition, line following, and obstacle avoidance) after starting mBot Mega, why?

You need to update the firmware to the factory version before you use mBot Mega. For details about firmware update, see Updating the Firmware of mBot Mega.


2. Why does the previous program disappear after I update the firmware?

mBot Mega can store only one program. Updating the firmware also restores the ex-factory program and therefore the previous program is overwritten.
