Dual channel wireless communication question

jmbertoncelli@USA

Hello,

I would like to know if having 4·x "912 MHz RF Transceiver" could be a good solution for my project.· I have a robotic rover and a computer laptop and my goal is to have the computer laptop responsible for the robot logic.· The robotic rover is propeller based and the control program on the laptop is multi-threaded.· I want that the propeller sending to the laptop realtime sensors information and navigation data (Telemetry), one cog could be responsible for this function·by sending data within an infinite loop.· A second cog·could be·responsible to receive the control command from the laptop.· Of course two channels must be open and dedicated to send or receive on both side.· The computer based control program has one thread for·outbound communication and another thread for inbound communication obvioulsy some other threads will be used (GUI, BACKGROUND data integration,...).

Does the "912 MHz RF Transceiver" be OK for this kind of job or should I look at XBEE-PRO (they are also less expensive than the PARALLAX RF TRANSCEIVER).

Thanks.

I really like the xBee. It already provides a full duplex channel with error checking and retries. You want a series 1 device though. The series 2 devices provide a network rather than a transparent full duplex channel. Read the documentation for details.
