iLogger Fw ver. 1.0.2:

  • Fixed” Live Telemetry on Single Vescs
  • Minor bug fixed and adjustments

iLogger Fw ver. 1.0.1 Most notable ChangeLog:

  • New” Logging format is now byte encoded, Allowing full precision and reducing storage space. Can also store multiple vescs data + GPS into a single record.
  • New” Folders hierarchy based on Year/Month/Day/Timestamps_.lg
  • New” Life time stats – Saved on SD Card under LT.Dat – Records total odometer distance and overall run time.
  • New” Multiple Export functions added : Formats are:
  • New” Automatic MTU negotiation and dynamic streaming rate of live data / records streaming to use the maximum supported rate over BLE.
  • New” Log All ESCs: <On – Off> Logs all detected Vescs simultaneously or only the master unit. When using CAN, iLogger attempts to detect and Log all Vescs on CAN network. When using UART, both master and slave Vescs are logged.
  • New” Log after time sync only: <On – Off> When toggled on, starts logging only after time has been synchronized automatically through Wifi or GPS lock.
  • New” Logging Type: <Log Manually – Log on Power ON – Log After Elapsed Time>: Three possible logging modes can be selected.
    • Log manually: Doesn’t start logging unless the “Start Logging” button is tapped, and doesn’t stop logging until “Stop Logging” button is tapped.
    • Log After Elapsed Time: Starts logging automatically on Power ON after a specified delay in Seconds.
    • Log on Power ON: Starts logging automatically on Power ON without delay.
  • New” Log Start Delay (s): When Log after delay is selected, logging automatically starts after specified delay in seconds.
  • New” UART Slave Vesc ID: When UART is used, specify slave vesc ID to allow dual VESC logging.
  • New” Updated charts on the app fixing many performance issues.
  • New” Logging status on the real time tab. Shows the current logging status.
  • New” “Start Logging/Stop logging” button on the SD Card tab with elapsed time since logging started.
  • New” Record viewing screen, shoes summary of all logged data (Multiple vescs and GPS data if available)
  • New” Expanded viewing screen, shows a more detailed view of each vesc data.
  • New” Power logs and calculation, shows total consumed power, max watts, regen, efficiency Wh/Mi etc…
  • New” Longer logging sessions are now possible, without limit.
  • New” Firmware version check when connecting to a device, making it easy to be notified when a new update is available
  • New” switching back and forth between vescs on live data views (on Both CAN and UART)
  • New” Timestamped faults
  • Improved” DieBieMS/ FlexiBMS support

Online system was also updated to be compatible with the new records format

Re-designed to focus more on important data, added energy and efficiency calculations, general stats like runtime, distance etc…as well as toggle between Imperial and Metric

You can now switch between all logged vescs from the online viewer.
