RobotMesh with other Python libraries?

Thanks, @tabor473 . I am interested in this bluetooth solution you’ve proposed. Can you provide a few more details?

The HC-05 chip you linked would plug into the cortex - would we need any add-on for the laptop? Does the laptop just output a standard bluetooth signal? How do you pair the laptop and the HC-05?

Additional thoughts:

Quick note - none of this is being used in competition.

Previously I’ve accomplished this using a MindSensors PiStorms interface and I’ve run the vision code using a Raspberry Pi. I’m looking to transition to VEX this year instead of LEGO MindStorms but I need to figure out if I can do the computer vision work.

I’m also wondering whether it would make sense to strap a Raspberry Pi to the Cortex and do some of the processing there. It’s not clear to me whether that provides any benefit over using the laptop over bluetooth.

Thanks for helping me think through this!

So it has been discussed here

It is really quite simple to use. Your laptop just needs to have built in bluetooth functionality. I just assume all of them do. A raspi would also work, communication between pi and cortex would have to be over UART anyway so the code would be identical on both ends. (Bluetooth, UART, USB are all categorized as just different com devices)

If you want the computer on board the pi would be better but I assume you already have a laptop.

I am one of the guys around the forum who works a lot with coprocessors and communication to laptops. Ran both of these projects.
