Which solution would you recommend?
QuoteWhich solution would you recommend?How much data? How often? What range? Is loss of any data acceptable?You could use an XBee (coordinator) at the PC, and XBee (router/end device) at each Arduino to send data to the coordinator. Depending on the antenna style and power level, you can get various ranges. The XBees manage the collision detection and retransmission, assuring no data loss.
