Forum Post: eZ430-Chronos Watch to Xbee RF Modules

Hi there,

I'm currently working on a project where I would like to use the eZ430-Chronos Watch as a mobile node in a wireless sensor network localisation system. My Chronos Watch is the 915MHz version.

Basically, I want to be able to receive a signal from the watch at multiple reference nodes, extract the RSSI from that signal, and use trilateration to calculate the watch's position.

I'm currently using Xbee 802.15.4 RF modules, which operate on a 2.4GHz frequency.

Are these modules capable of receiving an output signal from the Chronos Watch? And if not, would XBee Pro 900 modules (which operate between 900 and 928MHz) work instead?

Any help would be greatly appreciated.
