Best control method over Xbee link

Wireless & IoT
1

Hi,

Ok yes I’m kinda a new when it comes to arduino’s / Xbee’s and the like but alas its time to learn. . .

I plan on controlling two stepper motors and 4 relays wirelessly with an arduino with a Joystick Shield

Whats the best communication method for this??

  1. I/O Line Passing

shield/arduino → Xbee —//—> Xbee → stepper driver chip / relay’s

  1. UART

shield/arduino → Xbee —//—> Xbee → arduino → stepper driver chip / relay’s

Thanks for you help :slight_smile:

XBee series 1 virtual wire can do relays, of course.

And there may be enough bits left to do CW/CCW step pulses. But if you need recurring stepping pulses such as for locomotion, I think you need an aboard microprocessor. Just a small one, like an tinyAVR that talks to the serial port of the XBee for commands.
