Full Changelog: 0.9.8...0.9.9

Please note that due to the limitations of the SAMD21 flash, we are currently splitting the firmware in different build files. These builds are:

SAMD21 MCU:

• SCK2.1 Air: Firmware for SCK2.1 versions with Urban Board and Air sensors connected to the auxiliary port. Files: SAM_firmware_sck_21_air.bin (.hex, .uf2 also available)
• SCK2.2 Air: Firmware for SCK2.2 versions with Urban Board and Air sensors connected to the auxiliary port. Files: SAM_firmware_sck_22_air.bin (.hex, .uf2 also available)
• SCK Water: Firmware for SCK versions without Urban Board but with water sensors connected to the auxiliary port. Files: SAM_firmware_sck_water.bin (.hex, .uf2 also available)
• SCK2: Firmware for SCK2.1 versions with core functionality. Good for dev purposes. Files: SAM_firmware_sck_2.bin (.hex, .uf2 also available)
• SCK2.2 Air Test: Test firmware. Do not use.

ESP8266 MCU:

• ESP: Only one firmware file. ESP_firmware.bin

0.9.8-PM

This release includes changes to support the new PM sensor batch behavior (zero readings problem), and some other fixes:

• Fix PM reporting zero on first two readings
• Needed for old PM sensors: longer Serial timeout, more strict command verification, and clearing buffer
• Avoid turning off PM sensor on sleep when reading interval is too short
• Implemented PM passive mode
• Added PM sensor debug messages
• PM last reading now uses rtc instead of millis and warmUp as trigger period
• Empty Serial buffer on getReading to be sure no old data is consumed
• PM old sensors set passive mode on each wakeUp and add small delay between commands
• Added Support for external SHT35 Temperature and Humidity sensor
• Updated some Libraries
• Some minor fixes in building and flashing script make.py
• Updated production test code
• Fix disabling urban sensors persistence
• Fix error on enable/disable PM/PN sensor groups
• Added SD card detection debouncing
• Fix Sanity reset not always triggering
• Longer (10 min) force publishing every minute period.

Full Changelog: 0.9.8...0.9.8-PM

Pre release SAM 0.9.8 - ESP 0.9.3

All changes will be detailed here.

SAM 0.9.7

New in this release

• Added CCS811 command for manually change sensor drivemode.
• Preliminary release of battery calculator (WIP).
• Power related changes:
  • Battery capacity can be configured via shell.
  • Kit now go to sleep with and without battery after sleep timer (solar panel friendly).
  • Shell configurable sleep timer (30 min default).
  • Button or sd card events keep kit awake.
  • While wakeup kit will publish as soon as readings are available.
  • After timer, kit will publish every 3 min as default.
  • New default PM sensor reading every 5 min.
  • With default settings a 2000mAh battery should last at least 5 days.

Fixes

• Updated INA219 auxiliary sensor to use auxWire bus
• Update tools scripts to work with python 3.
• Fixed bug that prevents per sensor intervals to work properly.
• Updated noise compensation tables to improve readings on quiet environments.

There are no changes on ESP firmware 0.9.2 version is still the latest. It is also attached to this release for convenience.

SAM 0.9.6

New in this release

• Chirp Soil moisture sensor work:
  • After calibration normal Soil Moisture sensor returns percent.
  • New Soil Moisture RAW sensor delivers capacitance.
  • Calibration data is saved on SAM flash.
  • Integrated Chirp light sensor.
  • Added reset command to recover Chirp sensor default I2C address.
• Rename build build.py script to make.py to avoid confusion on usage.
• Updated I2C Aux sensor address list.
• Stop urban board disabled sensors on boot. Important for PM power savings.

Fixes
