mBot broken out of the box?

#1

I purchased an mBot for my daughters and it looks like it is broken out of the box. When I turn it on it does three tones, increasing in pitch. I press “A” on the remote and it beeps, if I try moving forward or backwards I just get the same three increasing tones. Sometimes turning right or left works, other times it doesn’t.

I did do a “Reset Default Program” through the “mBlock” application, but that didn’t seem to fix things.

I also have a Bluetooth module, but if I plug that in the whole board just beeps rapidly and nothing at all works.

Is it time to return it?

Thanks.

Try to Upgrade the Firmware before resetting the default program.

@tec_support, any other ideas?

Hi Make,

Yes, please upgrade firmware for mBot first, then reset default program again have a try. Here are the two instructions for detail steps:

1.How to reset default program manually.docx.zip (404.1 KB)
It is suggested to temporarily remove the Bluetooth module from mCore board while you try above steps.

Besides, sometimes, the mBot will function abnormal if it cannot get enough power from the battery. You may change the batteries for the mBot have try.
According to our test and research, it is suggested to use rechargeable Li-ion battery or rechargeable nickel-metal hydride, nickel-cadmium which can be bought from amazon or local shop. Or Alkaline battery with good quality like Energizer, DURACELL.
