Arduino Nano IOT disconnects while in Nano Motor Carrier

Official Hardware Nano Family Nano Motor Carrier
1

Hello, I have Arduino Nano IOT and Nano Motor Carrier.

  1. I was following this article, to set up these devices, but CHRG LED wasnt on.

  2. I have connected Nano IOT to PC, and was able to control DC motor from Matlab and Adruino IDE 2.

  3. I wanted to charge battery, that I connected in step 1, and the Tech Specs says, that the Nano Motor Carrier should be able to so after reading this, in Charging the Battery section I found out, that I have to solder VUSB pins in order to charge the battery.

  4. I soldered those pins.

  5. I have connected only the Nano IOT not connected to Nano Motor Carrier and was able to upload compiled sketch and connect it to Matlab as before.

  6. I was, once again, following article from first step, wanted to to setup both devices and got the CHRG LED to turn on, which was what I wanted.

  7. But now, while the Arduino Nano IOT is connected to Nano motor Carrier, I am unable to connect the Arduino Nano IOT to PC, it doesnt show up. Additionally, while the Arduino Nano IOT is connected to Nano Motor Carrier, the reset button, while pressed, doesnt turn off the ON LED and when trying to get to bootloader mode double pressing the reset button doesnt do anything

Thank you for any help.

To use both boards, you need to install the carrier library via manage library and the Arduino Nano IOT package core (via board manager).
Use IDE 2.0.3 and install all the dependencies that shows up after the installation.

I have the ArduinoMotorCarrier library and this it the other one I would say.

Does the Nano Motor Carrier power LED light up when the power switch is in the ON position? If the carrier is powered on correctly, try unistalling the IDE ( * Uninstall Arduino IDE) and re-installing it with all the dependcies.

I am having the same exact issue for weeks, and I doubt this is a software issue as MATLAB and any other device you plug this into does not detect it. I tried to install and reinstall multiple programs but nothing works. I think there is something wrong with the motor carrier itself rather than the IDE.

Reinstalling didnt work.
Also, when I upload Example DC motor test from Nano motor carrier library to arduino Nano IOT, while not connected to carrier and then, when I disconnect the arduino Nano from PC and connect it to Carrier and turn it on, I would expect the motors to start running, but it doesnt do anything.

And one guy on discord said something about motor carrier using pins 1 and 0 on the board, then it wouldnt connect to the PC, but I would expect being able to connect it to PC while in motor carrier while charging the battery.

Did you guys managed to find a solution? i have the same problem.
