I have the similar problem to

mBlock Ranger onboard LEDs not working properly

Hello, I received my mBot Ranger today, and I love it. Me and the kids started playing with it right away and everything went smoothly. However, we noticed that some times, only half of the onboard LEDs would light up when activating them through the APP. I just started testing the mBlcok development tooling, and while I was able to get a light show running at first, now only half the leds (1 through 6) seem to be working. Uploading the latetst firmware doesn’t fix this. Am I doing something…

Changing the battery or using the USB cable DID NOT work for me.
I am using mBlock for MAC in my class. some students have problem locating the bluetooth of the mBot Ranger

This does indeed sound like the same problem I had with my LED’s. Eventually, I ended up making a small recording with my phone and sending that in with a support request. Based on that, they had me send everything back under warranty. All in all, this was a good solution, since my new board works like a charm.

mBlock 5 had a lot of limitation. You will not able to complete the task in the ebook if you use mblock 5. My advise is to stick to mBlock 3 if you are teaching this unit.
