One motor won't go forward with Bluetooth

#1

Hi all first time user here. Bought my son an mbot for xmas. Super cool. Works great with the remote. However, when connected to Bluetooth I lose forward control of one motor. Firmware has been updated, motor connections have been swapped, and batteries have been tested and changed for good measure.
So…totally confused. Any help would be great.

Does the motor run properly when you remote control the bot using the IR remote?

#3

Yes. This is super aggravating.

I think you need help from @tec_support

Hi Maver1ck,

Please reset default program for the mBot with latest mBlock 3.4.5, you can refer to this document to reset default program.2.How to reset default program manually.docx.zip (677.9 KB)

Please note, temporarily disconnect Bluetooth while reset default program.
On the mobile devices side, please make sure you are using the latest version Makeblock APP in this link.

Once still the same issue after above, please kindly take a video to show the behaves on the mBot.
Besides, may I know what kind of batteries do you use? Do you use the rechargeable lithium battery?
