When you first connect the Arduino to your phone it will ask you for permission to access the USB device. Did you see this dialog?

If yes, you need to give permission.

If no, you probably have a connection issue.

Can you confirm you used the cable specified in the BOM? It needs to be an OTG cable (ID connected to ground)

I'm using One plus 5T which supports OTG(TYPE C USB Charging port). I tried Using Oppo F9 pro too(micro USB charging port)

  • Double-check the baud rate of App and Arduino are the same (they should be unless you changed something.
  • Try another cable.
  • Confirm your phone supports USB-OTG.

Yes it asked for permission to access the USB device. I gave yes and the openbot app opens automatically when my arduino nano is plugged into OTG. but when the app is opened it shows a dialogue text "Please Check the USB Connection". Why so?

I used cable converter. One is "Type C to USB female" and other is "Mini to USB male" i have attached my converter cables for your reference 4201bd64-8364-45ad-8ca6-8de23d9198cd

Should work in principle, but we never tried with adapters. Can you verify with another phone or device that the cables work?

thias15 commented 4 years ago

What happens when you try to toggle the connection switch in the app? Are you sure the Arduino has the firmware flashed correctly? Can you try to flash it again and then open the serial monitor to see if the Arduino is connecting and sending it's messages.
