The mechanism monitors confirmed transmissions from TX events (SMTC_MODEM_EVENT_TXDONE/SMTC_MODEM_EVENT_TXDONE_CONFIRMED) and the last_uplink_confirmed_requested indication. Upon detecting a consecutive number of ACK failures above a threshold, the supervisor temporarily activates a fallback mode with progressively increasing Spreading Factor (SF) until communication is re-established; then, after a defined usage window, the device returns to the standard ADR controlled by the network.</p> <p><br><strong>Modified file:</strong> lbm_examples/main_examples/main_periodical_uplink.c</p> <p><br>This artifact aims to support the reproducibility of the experimental methodology described in the study.</p> <p> </p> <p></p> |
