I recently purchased one Micro Maestro 12ch servo controller and two Xbee pro 60 mw wireless antennas (http://www.sparkfun.com/products/8742) together with two Xbee Explorer USB (http://www.sparkfun.com/products/8687). Our aim was to attain wireless communication with Micro Maestro through the two Xbee pro’s which communicate through Serial COM Ports. The picture bellow shows the working setup with direct connection to PC and everything went smoothly using the Pololu Maestro control Center.
But once we switch to wireless communication through the 2 Xbee Pro Modules, the Pololu Maestro control Center just doesn’t detect that the Micro Maestro is connected. ( Before hand, we tested the 2 Xbee Pro’s separately by connecting each of them to a different computer, we were able to achieve serial port communication between the two computers using Xbee’s X-CTU program.)
Now we don’t understand why it doesn’t work at all… I was browsing through the forums and came across this thread: Micro Maestro and Arduino FIO for 3 Servos and an ESC where it was mentioned that it is possible to “connect the XBee’s ground to the Maestro’s GND and connect the XBee’s TX to the Maestro’s RX” then it would work.
Much help and advice would be gladly appreciated!
