    RS1xx for transmission at a later time. With confirmed packets, if three successive uplinks are not acknowledged, the sensor tries to rejoin. Unconfirmed packets continue to be transmitted while the sensor is powered. https://www.ezurio.com/ © Copyright 2025 Ezurio All Rights Reserved...
  • Page 14: Adaptive Data Rate (Adr)

    Sensor starts transmitting Join requests alternately on a random 125-kHz channel at data rate 2 in the selected sub- Sentrius™ band and then a random 500-kHz channel at data rate 6. It continues this sequence until the sensor joins the network. https://www.ezurio.com/ © Copyright 2025 Ezurio All Rights Reserved...

    Most importantly, keep the sensor away from warm/humid environments after removing from the chiller/freezer • 8.4 LoRa Messages Note: The LoRa API is available in the ‘RS1xx LoRa Protocol Guide’ which is available from the RS1xx product page. https://www.ezurio.com/ © Copyright 2025 Ezurio All Rights Reserved...

    Every two unsuccessful attempts at a data rate causes the sensor to lower its data rate by one. Refer to the following tables for how many attempts are made at each data rate. https://www.ezurio.com/ © Copyright 2025 Ezurio All Rights Reserved...
  • Page 17: Disconnect

    This is required for the sensor to store data in the internal log flash. The sensor transmits data without the network time being available, but it cannot commit this to flash storage. This does not apply when configured for the Cayenne packet format, due to the protocol not supporting a timestamp. https://www.ezurio.com/ © Copyright 2025 Ezurio All Rights Reserved...
  • Page 18: Logging Feature

    While a unit is in the backoff state, it continues to read the sensor, but it stores its data to FLASH. The backoff period could be assigned to the sensor from which the backlog is extracted, other sensors in the network, or both, depending on the application. https://www.ezurio.com/ © Copyright 2025 Ezurio All Rights Reserved...
