EV3 to EV3 Communication

[shoringit]

I know that I can use Bluetooth communication between two EV3 bricks, but I'm wondering if there's a way to do it with a wired connection under pybricks. I know that it doesn't support the USB daisy-chaining that was supported in EV3-G, but I'm wondering if it would be possible to communicate between them using I2C?... Connect sensor-port to sensor-port and use IODevices to send/receive messages between the two programs... Is this possible? Has it been done before?...

Thanks,

Danny

You could make a modified cable that swaps the two data wires, and then use UARTDevice on both EV3s.

That's what I figured. I may have to test this...

It's also possible to use TCP/IP sockets over the USB cable.

With a little fiddling, the Pybricks mailbox stuff could be used with this (by replacing the Bluetooth RFCOMM sockets with regular network sockets).

Good to know. Thanks,
