Industrial IoT with Crystal-Free Mote-on-Chip

SCμM is a 2×3×0.3 mm ³ system-on-chip that contains an ARM Cortex-M0 and a 2.4 GHz IEEE802.15.4 radio. This paper describes the two-step calibration routine needed to run a full 6TiSCH stack on SCμM. It is, to the best of our knowledge, the first time a fully standards-compliant protocol stack runs on a crystal-free radio, such that it can participate in a network with off-the-shelf radios.
