No, the ZigBee module is inside the same enclosure as the PIC. The PIC
sends/receives data locally with the ZigBee module, which then
sends/receives this data to a base station. I guess what I said was a
little ambiguous. The PIC is merely using the module to communicate
via RF, but the timing of the RF link is entirely determined by the
module, not the PIC.
