Igaro C1

Firmware Changes Correct speed sensor detection not working on Garmin devices.

Firmware Changes Slow light duty ramping to improve boost wakeup prior to large power demand.

Firmware Changes Force Bluetooth appearance to Speed Sensor to work around Garmin incorrect BLE implementation.

App Changes Fix phone island area support. Remove storage full front/rear light config Add beam modes for low/high speed. Firmware Changes Ramp fast PWM duty on front/rear light enable to stop triggering a power warning event. Enforce 10% light output restriction on power warning event. Fix slow PWM duty potentially not setting on cycle. Fix hub tuning not enabling since 1.4.23. Remove beam transitioning. Hysteretic now always used. Add beam modes for hysteretic below/above speed values. Place USB disable back under hardware control. Remove storage full light config as without transitioning would likely to be only be set briefly.

Firmware Changes Revert UVLO speed change which may be the cause of false events since 1.5.0. Remove obsolete USB initialization code which would briefly turn lights off (not eye visible).

App Changes Rebuild with corrected firmware file. No change.

App Changes Update iOS SDK to v26. Add mppt frequency to metrics. Firmware Changes Convert PWM beam transition mode into hardware implementation. Convert PWM low duty output into hardware implementation. Improve very low speed/storage discharged brightness/stability. Fix ultra low band not enabling on storage decrease. Remove hysteresis from ultra and low bands for smoother power scaling.

App Changes Mitigate library error which could result in random connection failure on iOS. Improve speed calculation to ignore last value when time exceeds int16_t maximum.

App Changes Add support for showing dynamo AC frequency (click speed twice). Consume BLE CSCS service data correctly. Firmware Changes Add hysteresis to front low/main beam transitioning to eliminate small frequency variations causing light flutter. Switch the LED PWM driver from 60Hz to 70Hz. Correct the BLE CSCS implementation (now tested on various Apps such as Wahoo Fitness, OSMAND).

App ChangesChange motion timeout values from 1s to 0.5s intervals. Fix animation working on correct face when using ambient override. Add further debugging to trace sporadic iOS connect issue. Firmware Changes Overhaul motion capture method to eliminate delay and improve accuracy. Improve storage read method for less variance resulting in less hunting when on the boundary between switching light levels. Improve MPPT read capturing to use fast motion capture for improved power extraction.

Firmware ChangesResync version to fix bad Apple push. No change from 1.4.15.

Firmware ChangesAuto updates values for new functionality released in 1.4.11 where those values haven't been set (either manually or via reset).

App Changes Add support for full-charge output level settings for front/rear outputs. Update RPM calculations for corrected BLE speed profile. Revert BLE module to hopefully fix random BLE characteristic value swapping on iOS. Simplify info/error information. Firmware Changes Add full-change output level settings for front/rear outputs. Enhance accuracy of RPM values exported to BLE speed profile. Tweak default configuration front/rear output values to align with hardware efficiency characteristics.

App Changes The Bluetooth management code has been refactored to be more fault tolerant with corrected recovery in such cases. Firmware Changes A bug which prevented established Bluetooth link updates has been corrected. A Bluetooth issue which kept the CPU awake has been corrected. Testing shows this has dropped CPU power usage ny half. Bluetooth link updates were only implemented for the first connection. With multiple connections now possible this has been corrected.

App ChangesAdd a 15s failsafe timeout for Bluetooth connection tasks.Force order of Bluetooth disconnect clean-up operations.Correct Bluetooth connection tasks potentially not capturing errors.Fix App crashing when going into background (which then required an unnecessary reconnection).

App Changes The current motion/ambient/storage configuration is now animated. Firmware Changes Fix speed time value overload on 1/64 reads. Fix rear light using front light duty ramp values. Fix front/rear light flickering due to bouncing between duty ramp values. Change default moving/dark/band #2 front & rear brightness from 30% to 20% to allow faster charge into band #3 where increased hardware efficiency will maintain a higher brightness. Current users are recommended to reduce the values manually.

App Changes Overhaul Bluetooth code for more reliable connecting and connection handling. Switch Status polling nature to new push notification implementation. Switch Speed/Frequency to Speed/RPM consuming new Cycling Speed and Cadence Service. Firmware Changes Change shutdown timeout to cancel on motion detected and moving. Add Bluetooth Cycling Speed and Cadence Service (use Igaro C1 as a speed sensor for Wahoo etc). Remove polling nature of Status updates and replace with push notifications. Overhaul Bluetooth code for execution, fault tolerance and supporting multiple devices.Fix Bluetooth disconnect causing hardware reset.

App Changes Fix blank screen issue on iOS introduced in last version due to unpublished resources. Update Bluetooth library for iOS.

App Changes Add Velogical Trekking rim dynamo to options list. Detect Apple iPhones with island and move navigation tabs. Fix value sync issues for SP dynamo hubs Firmware Changes Add Velogical Trekking rim dynamo support.

Firmware Changes Minor optimization to LED PWM/effects timing. Won't be human eye visible.

Firmware Changes Fixes setting and saving Bluetooth advertising power crashing the CPU on reboot.

Firmware Changes Adds a hidden means to wipe settings.

Firmware Changes Disable motion noise implementation until further testing can validate approach. Original reason for introduction no longer applicable. Correct hub tuning potentially not enabling due to race condition. Correct mppt using preductive rather than ramp for some event triggers Fix hub tuning potentially being left on after mppt has disabled resulting in unnecessary current consumption.

Firmware Changes Bootstrap capacitors backup charge timing change.

App Changes Switch motion timeouts from half-seconds to seconds. Firmware Changes Resolve very unlikely to occur boot issue where the C1 would appear faulty until super-capacitors decreased below 4v. Resolve incorrect timing execution of scheduled tasks. Switch motion frequency to pure hardware implementation for supporting fast AC sources, add over-sampling and other optimizations. Fix buffer-overrun error which could conflict with MPPT shutdown. Merge two timer resources for slightly lower power usage. Increase storage over-sampling to reduce light hunting between storage increase/decrease.
