Changed

• Applied markdown lint to markdown files
• Bumped TinyGSM dependency
  • Changed datatypes for modem voltage outputs.
• Switched from Soligen fork of ADS1115 library to the standard Adafruit version. #456

• Consistently apply all pre-processor defined checks with function-like syntax
• Consistently check for both __AVR__ and ARDUINO_ARCH_AVR in all cases.
  • Not all AVR boards defin __AVR__ within the PlatformIO system, which was confusing the SCons preprocessor.
• Modified implementation of initial short logging intervals.
• Allow non-sleep before returing from testing or logging functions.
• Modified returns of modem variables from uint's to int's for consistency with the latest version of TinyGSM.

v0.35.1 2024-08-26

This is a hot-fix type release, pushing out fixes for sleeping for the SAMD21. It is not fully tested. If you are not using a SAMD21, please stick to version 0.35.0 until 0.36 is released.

Changed

• BREAKING Switched default clock for SAMD21 from the built-in 32bit RTC to the DS3231.
  This is not be a permanent change.
• Switched to reusable workflows for CI

Fixed

Fixed clock configuration for SAMD21

Changed

• BREAKING Refactored how the publisher transmit buffer works. This will require adjustment to custom data publishers.
• Update GitHub actions
• Remove date from copyright for easier tracking
• Turn modem off at end of setup, regardless of time
• Clean function to set file timestamp on SD card
• Use equation rather than table for CSQ
• Only polling modem for enabled parameters
• INCREASED THE MAXIMUM NUMBER OF VARIABLES FROM A SINGLE SENSOR and implemented an option to set this by build flag.
  • This will increase memory use for the entire library.
    If you are not using the GroPoint sensors which require many variables, I recommend you change this value via the build flag -D MAX_NUMBER_VARS=8
• Allow all WiFi modems to first attempt to connect using existing on-modem saved credentials rather than immediately sending new credentials.
• Add further debug printouts to the processor stats

Added

• Support GroPoint Profile GPLP-8 Eight-Segment Soil Moisture and Temperature Profiling Probe
• Support Vega Puls 21 Radar
• Functions to enable and disable modem metadata polling by bitmask

Removed

• Removed the (unused) sendOffset parameter from dataPublisherBase.

Fixed

• Minor bug fixes for XBee Wifi
• Handle no SIM card response from SIM7080G (EnviroDIY LTE Bee)
• Fixed Keller debugging output.
• Fixed file reference for SDFat 2.2.3

Known Issues

• The modem hardware, firmware, and serial number is only implemented for the Digi XBee WiFi.

Changed

• BREAKING - Removed support for light sleep on Espressif modules.
  This changes the order of the constructor for the ESP32 and ESP8266!
  • The light sleep mode is non-functional anyway, and confusion over the sleep request pin was putting the board in a position not to sleep at all.
• Minor tweek to clang-format
• Moved all variable initialization to default header values and initializer lists
• Converted all "c-style" casts to static casts
• Switched cases of strcat and strcpy to snprintf
• Specify python version 3.x for actions (used by PlatformIO)

Added

• Support Campbell RainVUE10 SDI-12 Precipitation Sensor #416
• Support YosemiTech Y700 Pressor Sensor (#421)

Removed

Fixed

• Fixed bug in YosemiTech Y4000 Sonde (#420)
• Fixed non-concurrent data fetch for SDI-12 when NOT using debugging.
• Fixed internet connection when in "testing mode"
• Allow a non-zero wait time for SDI-12 sensors
• Fixed outdated GitHub actions

Fixed

• Increased warm-up and measurement time for Campbell ClariVUE-10 to work with the latest version of the sensor.

Fixed

• Increased measurement time for Hydros21 to work with the latest version of the sensor.

Fixed

• Fixed script to install and zip libraries for a release

Changed

Added

• Added a typedef and header for the ESP32
  • This is just another name to the ESP8266 class to help any who don't know they're identical for our purposes.
• Example: Created a new DRWI wifi example for workshop.

Removed

Fixed

Changed

• Breaking: Renamed the static markedEpochTime variable to markedLocalEpochTime.
  • This was sometimes used in "complex" loops. Code utilizing it will have to be changed.
  • This is part of the effort to clarify where localized and UTC time are being used.
    We recommend a logger's real time clock always be set in UTC and then localized for printing and storing data.
• Breaking: Renamed the function setNowEpoch(uint32_t) to setNowUTCEpoch(uint32_t).
  • Although public, this was never intended to be used externally.
• Breaking: Renamed the YosemiTech Y550 COD sensor as Y551. See below.
• Potentially Breaking: Changed the default "button" interrupt pin mode from INPUT_PULLUP to INPUT and created optional arguments to the setTestingModePin and setLoggerPins functions to specify the pin mode and pull-up resistor state.
  • INPUT is the proper mode for the Mayfly.
    The Mayfly has an external pull down on the button pin with the button being active high.
    This means having the pull-up resistors on negates the button signal.
    The pin mode had been set as INPUT_PULLUP for the button, backwards for the Mayfly, since July of 2017.
    By some electrical luck, with the 0.x versions of the Mayfly, the external pull-down on the button pin was strong enough to out-weigh the incorretly activated pull-up resistors and an interrupt was still registered when the button was pressed.
    With a different pull-down resistor on the Mayfly 1.x, the button no longer registers with the pull-up resistors active.
    So, for most of our users with Mayflies, this will be a fix.
    But for anyone using a different board/processor/button configuration that depended on the processor pull-up resistors, this will be a breaking change and they will need to specify the button mode in the setTestingModePin or setLoggerPins function to return to the previous behavior.
• Added a longer warm up time and removed some of the modem set-up to work with the ESP-IDF AT firmware versions >2.0
• Made sure that all example clock synchronization happens at noon instead of midnight.
• Renamed Classes: Renamed several classes for internal consistency.
  These are not breaking changes at this time; the old class names are still usable.
  • Rename class MPL115A2 to FreescaleMPL115A2
  • Rename class MPL115A2_Pressure to FreescaleMPL115A2_Pressure
  • Rename class MPL115A2_Temp to FreescaleMPL115A2_Temp
  • Rename class TIINA219_Volt to TIINA219_Voltage
  • Rename class PaleoTerraRedox_Volt to PaleoTerraRedox_Voltage
  • Rename class ExternalVoltage to TIADS1x15
  • Rename class ExternalVoltage_Volt to TIADS1x15_Voltage
• Documentation: Migrated to latest version of Doxygen (1.9.3).

Added

• Sensor Added support for the YosemiTech Y551 COD Sensor, which makes a UV254 light absorption and translates it to estimates of Chemical Oxygen Demand (COD) (or Total Organic Carbon (TOC)) and Turbidity.
  • NOTE that this upgrade removes the earlier Y550 from the library, as it was never tested and is no longer available form YosemiTech. If anyone has a Y550 sensor, the Y551 commands should work. Let us know if they don't.
• Sensor Added support for the YosemiTech Y560 Ammonium Probe, which is a mini sonde for three Ion Selective Electrode (ISE) sensors (pH, NH4+, K+) that together are used to provide a corrected estimate of total ammonium nitrogen (NH4_N) in mg/L.
  • NOTE that this release only includes outputs for NH4_N, pH, and temperature. A future release will also include estimates of potassium (K) and raw potential values from each of the electrodes.
• Sensor Added support for the SDI-12 In-Situ Level TROLL 400, 500 & 700 Data Loggers
• Sensor Added support for the Sensirion SHT40 relative humidity and temperature sensor
• Sensor Added support for the Everlight ALS-PT19 ambient light sensor
• Sensor Added support for the Bosch SensorTec BMP388 and BMP390 pressure sensors

Removed

Fixed

• Fixed memory leak for AOSong AM2315 thanks to @neilh10

Changed

• Restructured SDI-12 slightly to break out the start measurement functionality into a new function.
• Modified Decagon 5-TM and Meter Teros 11 to use the SDI-12 get results function rather than addSingleMeasurmentResult.
  This will allow both sensors to honor the 'non-concurrent' flag, if that is set.
  Previously, they would not have.
• Documentation: Migrated to latest version of Doxygen (1.9.2).
  This required some changes with m.css to properly ignore the doxyfile.xml the current version generates.

Added

• Board: Adds 1.0 and 1.1 as valid version numbers for the Mayfly. Does not yet support any new features of those boards.
• Add a new parameter (internal variable) to the sensor base class for the number of internally calculated variables.
  These are used for values that we would always calculate for a sensor and depend only on the raw results of that single sensor.
  This is separate from any calculated variables that are created on-the-fly and depend on multiple other sensors.
  In many cases, this is 0 and in most of the other cases the value is informational only.
  For the SDI-12 sensors, I'm actually using this to make sure I'm getting the number of values expected.
• Sensor: Added support for v0.2.0 of the EnviroDIY/TippingBucketRainCounter device firmware, which added capability to count rotations on a reed-switch anemometer and fixed a critical bug that failed to count high rainfall rates.
