Firmware Changelog
Correct power values depended on having zero offsets that were accurate to a level that in practice was difficult to achieve. This is no longer the case.
When recording High Speed Data, a number of samples were being discarded and not recorded to the .fit file. This has now been fixed.
Some power meters exhibited occasional erroneous values in the output column of the Calibration page. The underlying issue has now been resolved.
Power/force is now being measured in the thrust plane only (the plane normal to the blade face). Only a negligible amount power/force is generated in the orthogonal plane, so this change shouldn't have a noticeable affect on the total power values.
The LED represents the remaining battery capacity (when not charging) and no longer represents the connection state. Every five seconds the LED on each shaft will blink for a short period up to five times. Five blinks represents 80-100% capacity, four blinks represents 60-80% capacity etc. The LED blink will switch to 'breathing' mode when charging (on for one second, off for one second). This 'breathing' will change to on for 5 seconds, off for 10ms when the shaft is fully charged.
The transmit power for the bicycle power meter ANT+ channel has been increased from 0dBm to +4dBm.
The firmware version running on the left shaft (kayak) is now displayed in the Web Bluetooth app.
The 'Power balance' metric was found to favour one side of the stroke. This has now been fixed.
ANT+ displays will now correctly interpret the power values as per stroke (rather than per second) and subsequently store them in the .fit file in a physiologically appropriate manner where each sample represents the average power output over the recording interval (typically 1s).
The battery state of the left shaft (kayak) is communicated by the right shaft (kayak) to the Web Bluetooth app using a different protocol (to support Polar head-units and accessing the Web Bluetooth app on iOS). Web Bluetooth app v0.0.17 or higher is required to correctly receive the left shaft battery state.
Support for Polar head-units (tested with M460 and V800).
Deep sleep mode triggering issues.
Increased wake-up motion threshold from 750mg to 1000mg.
The left shaft (kayak) no longer appears as a cycling power meter to prevent the user accidentally connecting to the left shaft over Bluetooth (when the right shaft (kayak) is asleep) when using e.g. the Wahoo 'Fitness' app.
Active gain error compensation of the load cells analog-to-digital converter.
Support for the Kayak Power Meter model (without High Speed Data).
