  Long range wireless connectivity opens the door for new IoT applications. Low
energy consumption is essential to enable long autonomy of devices powered by
batteries or even relying on harvested energy. This paper introduces
technologies for long-distance interaction with energy-constraint embedded
devices. It proposes sleepy strategies for power management for the platform
and the transmission. Adequate signal processing on the remote modules is
demonstrated to play a crucial role to sustain the autonomy of these systems.
The presented open-source development platform invites the signal processing
community to a smooth validation of new algorithms and applications.
