Tech - CORE Changelog
The changelog outlines the key updates and improvements to the CORE sensor firmware. Please follow this link for information on updating / changing CORE sensor firmware.
0.8.2 (2023-07-09)
- Fix bug with COROS watches
0.8.1 (2023-06-19)
- Implement advanced algorithm switching mode logic (default ‘simple switching’)
- Enable ANT writing into Moxy (with default value core temp in both SmO2 and THb)
- Allow up to 3 simultaneous BLE connections
- Improve iOS Firmware update speed
- BLE connection improvements
0.8.0 (2023-02-23)
-
Enables concurrent use of the CORE app and a Bluetooth client (e.g. BLE smartwatch)
- Reduced ripple on ANT+ and BLE body temperature signal output
0.7.4 (2022-08-10)
-
Improved resolution of history data interval to once every minute (before: once every 5 minutes)
0.7.3 (2022-04-29)
- Improvements on the smart algorithm switching.
- Fixes excessively high temperature readings after removing and re-positioning the sensor. Note: equilibration time until first value is displayed might increase in cold ambient situations.
0.7.2 (2022-03-01)
-
Fixes excessively high temperature readings at the beginning of a workout.
0.7.0 (2022-02-02)
-
Smart algorithm switching
-
CORE automatically switches to low activity algorithm when approriate (rest, sleep), even when heart rate monitor is paired.
-
-
Last 4 digits of CORE ID added to the device name
-
In app device scan, device will show up as "CORE 3A:5F" instead of "CORE"
-
Facilitates identification of unkown devices under iOS
-
Note: Only applies if no nickname is set
-
-
Adaptions to Bluetooth Health Thermometer Profile (HTP)
0.6.0 (2021-09-24)
-
Adapted LED feedback:
-
Battery state of charge indication upon shaking core
-
Adapted blink pattern to indicate heart rate monitor connection status
-
"slow blink" pattern when core is charging
-
-
Standby mode support (Requires CORE app 1.3.5): Increases time between re-charges to up to 5 weeks
-
Bugfix: ANT connection logic leading to heart rate re-connection problems
-
Shaking CORE leads to an addictional scan for heart rate monitors
0.4.1 (2021-06-21)
- Improved handling of bad heart rate signal
- Data quality as low in case of extreme jumps in HR signal
- Intermediate better support on Wahoo bicycle computers
0.4.0 (2021-05-26)
- Activity algorithm dynamic switching without necessary algorithm reset:
- This is a big change internally when transitioning between the 24/7 Everyday Living algorithm and the Sports Algorithm (with heart rate monitor)
- Bugfix: Guard against sports algorithm rare crash (scaled feature)
- Improved "cold start" for greater initial accuracy
- Heart Rate values < 30 are now regarded as invalid
- Proper rounding for skin_temp in ANT CORE profile
0.3.20 (2021-04-23)
- Set data quality to 0 if charger is plugged-in
- Reset CoreTemp and quality when leaving a measuring mode
- Miscellaneous internal bug fixes
0.3.19 (2021-03-24)
-
Update on data quality 0 is used
-
Always save history independent of quality (before: only saved if quality>0)
-
Continuously update BLE health thermometer profile core body temp value
-
send notifications if enabled
-
transmit IEEE11073-NaN if quality == 0
-
-
Research mode channels fields logging updated
-
Server unit calibration settings verified and synced properly
0.3.18 (2021-03-10)
- Auto-fix too many paired Heart Rate monitors bug at firmware startup
- Updates to the research mode functionality
0.3.17 (2021-02-17)
- Add standard BLE battery profile
- Run ANT Heart Rate monitor search after new device paired or new measurement started
- ANT Core profile: page0 HR status now indicates active HR connection (instead of 'min. 1 device paired')
- Miscellaneous internal bug fixes
0.3.16 (2021-02-04)
-
Quality score in no-sports mode now based updated to more relevant value
-
ANT Core profile
-
allow pairing with wildcards
-
handle page70 requests for pages 0 and 1
-
transmit correct ANT page0 HR source status
-
HR pairing via ANT
-
0.3.15 and earlier
