We're planning on using Arduino for a telemetry system. The input data comes from RS232, and we'd like to communicate with another Arduino via XBee. We bought already the XBee shields as well as the Arduinos. The question is: would a RS232 shield for Arduino use the same ports as XBee? Because they should be working at the same time...
Hope I made myself clear.
P.S.: The RS232 shield we're planning to use is: http://dx.com/es/p/rs232-serial-port-to-ttl-converter-communication-module-for-arduino-148963?tc=EUR&utm_source=GoogleShoppingSP&utm_medium=CPC&utm_content=148963&utm_campaign=Arduino_&_Suministros_de_Chips_para_Microcomputadores&gclid=CPvT1uns2bcCFWfItAod-DcAOQ and now we've several digital pins free.
