Unable to Upload Code to mBot, timeout error

I have just purchased the Mbot for my kid and he wrote a very simple block code but when we tried to upload we were not able to

here is the error -
Error: Sending 3020: receiveData timeout after 1000ms

Hi Dipteshd,

I have checked the web version as it bugs every now and then, but it looks okay. It is worth a little more information.

Web version with mLink or Local?
PC, MAC, Linux, Tablet?

When you indicate simple code. Did you try the starter block and simply turned on the 2 lights in red ??

It is resolved, i have an old mac so I switched to a PC ,

I have the same problem. I’m using an hp laptop that isn’t very old and I’m trying to upload block code to my mBot, but it’s saying Error: Sending 3020: receiveData timeout after 1000ms. I’m using Microsoft Edge as a web browser. I’ve tried using Google Chrome, but whenever I try connecting a device (mBot) it says Download and install mLink 2 now to connect devices for coding. Even though I already have mLink 2 downloaded, every time I try to connect the device, that message pops up.

Also, I don’t know what these mean, but it also said in red text: mcore.upload_fail_fded06b5
mcore.upload_fail_17773a37

@rackofshad @Dipteshd Did you make sure that Edge can access your ports, mLink is running, and that you connected the bot to the correct port?

@MINARDI welcome to the forum! Please see the post here:

And try some of those steps.

Is this a standard USB too USB port device connection? What port are you connecting to in the software? Provide some more info or screenshots of your steps, so I can troubleshoot further. Thanks!
