  • Page 28 • Barometer (pressure) Default Operation The analog sensors are sampled at the Sample Rate. The current sample is compared to the previous sample. A sensor reading is transmitted if the difference between the two readings is greater than the configured delta. The Reporting Period ensures that a sample is transmitted at the configured period or less.

Door/Window (Reed Switch) Operation The reed switch sensor detects a magnetic field near the notch on the right-hand side of the device. Ensure that the notch on the magnet and the notch on the device line up with minimal gap when the door or window is in the closed position.

  • Page 31: Data Caching

    6.4.5 Data Caching (v0.60.0 and later) The Data Caching feature allows failed confirmed uplinks to be stored locally for later retrieval. Data Caching is enabled through configuration parameter 0x0D (see section 6.3.3). Currently only MQPS uplinks are supported. Only confirmed uplinks are eligible to be stored, as set by configuration parameter 0x0A.

  • Page 33: External Temperature Probe Calibration

    Example: Request all available records. The first record found, with timestamp 1 January, 2023 at 00:00, is a temperature report of 23.0 C. The second record, with timestamp 2 January, 2023 at 00:00, is a temperature report of 22.9 C. The full report could not be sent in a single uplink, so more uplinks are sent until all records are reported.

  • Page 34: Get/Set Calibration Configuration

    Piece wise linear interpolation is used to calculate the actual or calibrated values between points. The nearest line segment will be used for points outside the defined calibration points. At least two calibration points must be defined to enable calibration. The calibration points are created/removed/inspected using the following LoraWAN payloads on FPort 218.
