Using Device Info for Troubleshooting your Coder

It can be helpful to understand what Coder cards the Coder is actually reading, so that you can better understand how and why your robot's behaviors are occurring in a project. Within the Classroom App, the Device Info section can be used to see the Coder cards that are in a Coder, as well as any card errors. You can use that information to help you better understand your robot's functionality, and have an additional troubleshooting tool to use if you suspect something is not working as expected.

Coder card errors

If a Coder slot is empty and does not have a Coder card in it, it will show as a blank space in the project slots. An empty slot in a project could cause the project not to run as intended.

If a Coder card is not inserted properly (upside down, backwards, bent, etc.) the Device Info will show 'Card Read Error'. Remove the Coder card, and reinsert it correctly.

If a Coder card is damaged, it may read as a different command altogether. 

Viewing the Coder cards in the Device info can be useful to validate that the Coder cards in a project are all being read correctly.
