Can you Rename the Bluetooth name in the mBot?

#1

I am going to be teaching a community college robotics class with the mBot. It would be nice if you could rename the BlueTooth name of the mBot from MakeBlock, so I don’t have a room full of the same names. Does anyone know how to do that?

Hi ITInstructor,

The Bluetooth name can’t be modified to be unique since it is integrated inside the chip.
We have no way to change it.

While, we have plan to purchase new Bluetooth which has unique name afterwards.

Hi, maybe it’s possible.

This kind of module has a set of AT command that you can use to change a few stuffs.
Searching in internet for this module i found out this:
https://beststore-online.com/item?id=44464097771&vendorId=telesky旗舰店
in which are listed the supported AT commands.

So i tried to connect the BT module directly to a pc using a USB to serial adaptor (few dollars on ebay).
Then i used a terminal sw (you can use Putty as well) to send the AT commands to the module.
It seems to work!

Ask for the version:
AT+VER?
+VER:(Makeblock)Ver2.3.17.2(Apr 21 2015)

ask for the MAC:
AT+MAC?
+MAC:000D1903172B

ask for the name:
AT+DNAME?
+DNAME:Makeblock

change the name:
AT+DNAME=SuperMario
OK

asking for the name again:
AT+DNAME?
+DNAME:SuperMario

I still have to try if it works 100% on the mBot, but it seems ok.
Enjoy!

That was a good thought. However, it doesn’t show up in mBlock as the rename, but as Makeblock. I tried renaming the at+lename, but then mBlock doesn’t find it. It seems the mBlock is hard coded to Makeblock.
