Some or all of the sensors on the Smartsuit Pro do not work

You managed to connect the Smartsuit Pro in Rokoko Studio, but you notice that some, or all of the sensors of your Smartsuit Pro don't work. Sensors can fail for one of two reasons:
During a firmware update, some or all the sensors got stuck in bootloader mode.
Sensors are physically damaged.

*Solution  - Sensors stuck in Bootloader Mode

Sometimes during a Firmware update sensors can get stuck in the bootloader mode. This can for example be caused by unplugging the USB-C cable before the update has finished successfully, or if the hub was underpowered during the update. This results in not fully functioning sensors that are constantly blinking green or lighting blue (physically, not in Studio) and are displayed grey in the Rokoko Studio diagnostics panel.

Below is an example of grey sensors not responding :

Instructions to debug sensors stuck in bootloader mode

Table of contents:

Part 1: Get COM port from Command Prompt & Make all sensors stuck in boot
Part 2: Get sensors out of boot

Part 1: Get COM port from Command Prompt & Make all sensors stuck in boot

Download and unzip to the desired destination:

Please make sure that Rokoko Studio is not running.

Open a terminal (cmd) and navigate to the unzipped directory that contains the content of If you are not used to working with the command prompt, here is some guidance:

Unzip the to a folder, for example on your desktop
Open the command prompt
Directly type cd Note: there is a space after "cd"
Drag and drop the unzipped Fixfrombootv2B folder in the command prompt

In the terminal type: 1 followed by Enter. 


Press any key to continue. At this point If there's a Smartsuit Pro connected, this command will show the USB COMx port that the suit is connected to in the last line


Enter the number as per COM# ( just the number ) and hit Enter. If the COM number is 10 or higher, then the full name of the COM will look like this  \\.\COM10 In this case follow this guide to lower your COM# to a single digit number ( COM# <10 )


Press any key to continue and be ready to disconnect Smartsuit when you see the message below 


Now you should see the message above ( as shown in screenshot .) Press any key to continue and proceed to step 2 of the procedure. Unplug SmartSuit Pro and wait 10 secs to replug it.

Plug the Smartsuit Pro back to the computer and verify that all the sensors are blinking green. If they are not, repeat step 1 and increase (or decrease) the time you spend to unplug the USB.

Part 2: Get sensors out of boot

All sensors should be now blinking (stuck in boot loader).
In the command prompt windows type: 2 followed by Enter.
You will have to input again the COM# you get


Press any key to continue and let the process finish. After a while you should see the following :


Press any key to continue and exit.
Unplug your SmartSuit Pro and after 10 secs replug.

Start Rokoko Studio and verify that SmartSuit Pro is working as expected.

If the steps didn't work on your first try please repeat it 1-5 times.
