Application Help with Choosing an RF protocol

Mike C56083

Other Parts Discussed in Thread: CC2564

I am currently in the processor of looking over various RF protocols for use as basic cable replacements in some measurement devices. These devices take various readings and would in most cases be continuously sending data when the sensor is being used. I have been looking at the ZigBee, Bluetooth (classic and low energy), and the 433 MHz band.

My main factors would be the ability to operate from 2 AAA for months, operate at about 20ft, cost <$20, and be FCC approved.

I am very interested in the bluetooth low energy modules TI has coming out (specifically the CC2564) however I am unsure if my application would constitute BLE use...

I was hoping someone might be able to help me atleast narrow down the field to one specific protocol (right now I am looking pretty hard at bluetooth but I would definitely be swayed by logical arguments).

 

Thanks

    You mention a little bit about your application, but the specific answers to these questions will better help determine the right technology for your application:

    1. What data rate is required? Is the data bursty, or a steady stream?

    2. What kind of latency is required?
