Using RB-Dfr-148 as an "XBee shield" for Arduino?

Lynxmotion Rovers, Sumo, and Tracked

Hi all,

RB-Rbo-40 includes an XBee USB adapter so that you can plug one of the XBees into a PC to drive the rover. My question is, could you use the adapter’s TTL connections to connect it to another Arduino instead of a PC? So the second Arduino takes the place of the controlling device, instead of a PC?

Many thanks,

Hi,

Thanks for the reply :slight_smile:

OK, that’s great. Thanks very much for your help :slight_smile:

We’d love to see a video of it working.

Received Signal Strength Indication. You can see where it’s connected in the schematic.

If the light is strong / solid, you have a good signal.

Can you upload a video showing it in action? Always curious to see what customers are doing with their Rovers.

Of course! Planning to make a joystick module? Upload a video if you can - we’d love to see what you are working on.

You don’t really need to connect DTR - just Tx / Rx / V / GND.

Hi Coleman,

This works very well, thanks for the tips. I’ve used it to build a wireless Nunchuk-based controller for driving the DFRobotshop Rover and operating a pan/tilt rig. There’s a 900MHz camera on the rover, and I’m now adding a TV overlay board to the controller so that I can overlay the rover’s telemetry onto the TV feed.

When it’s finished :wink:

Hi Coleman,

What does the RSSI LED on the RB-Dfr-148 denote?

Many thanks,

Hi Coleman,

So when it’s on/off, it means…? Good signal? Bad signal?

Many thanks,

…and here’s a quick shot of what I’m working on (minus the lid). I had to change the Nunchuck for a pair of 2-axis joysticks due to timing conflicts with the video overlay shield:

In the background you can see the receiver for the camera on the rover, which connects to the overlay shield. One of the joysticks drives the rover and the other operates the pan/tilt rig.
