Hi

Congrats you just found a bug, we will fix that in the next release in the meantime

Just copy this folder

C:\OttoBlockly\compilation\arduino\packages\arduino\hardware\avr\1.8.3\libraries\SerialCommand

Into this folder

C:\OttoBlockly\compilation\arduino\packages\arduino\hardware\megaavr\1.8.6\libraries

and then it should work as you see here:

Hi @Johnny Acevedo12 

Otto Ninja uses Wi-Fi for communication, NOT Bluetooth, you will find out the steps on this guide.

The app is ready to download if you simply scan the QR code from the package, or you can also go to this link https://remotexy.com/en/download/14 or search "RemoteXY: Arduino control"  in the Google play or Apple Store

Hola @Javier Sanz37 

Yes we are just documenting but just follow this steps.

1. Upload the code attached then Open App
2. Press + Add new device
3. Select Wifi point

(Make sure to have wifi disconnected from other networks) and power Ninja with battery all time.
