Lights rgb in core always red don't become green or white

#1

Hello,

Mbot has always works fine, but when we put the mbot on on now, the lights in the core don’t become white, they’re still red. When we put him on usb, the mbot re-works fine. Is it possible that the bluetooth card is broken?

Thanks

Hello Eva,
Good morning~
You can download Makeblock App (ios or android), check if you can connect mBot with Bluetooth and control it.
To run online program, please make sure you have done “firmware upgrade”.
Connect mBlock to mBot with PC built-in Bluetooth, it may get worse compatibility than Makeblock Bluetooth dongle. And mBlock 5 may not work with PC built-in Bluetooth.
Also make sure battery is fully charged.
