battery-powered device (BPD)

A device on the mesh network that is powered by a battery and that communicates across the network through a neighboring continuously powered device (CPD). Examples are:

• Gas Interface Management Unit (IMU) Module

• Milli

• OpenWay Riva 500G ERT Module

• OpenWay Riva 500W ERT Module

To conserve power, BPD transmitters are usually in "sleep" mode. When a BPD first joins the network, it finds the best neighboring CPD as its proxy. Under normal operations, following a negotiated "listening schedule", the BPD wakes up and exchanges data, messages, and firmware updates with the CPD. Commands issued to the BPD are sent to the CPD, which returns answers after the BPD's next successful "wake" cycle. See also battery backed device (BBD).
