Known Issues

• General workaround for issues: delete and reinstall the app.
• License Activation problems found for some phones.
  Workaround: remove/close the app from Android tasks list and restart the app. Restart the phone and keep internet on the first time to let Google Play to sync the account.
• Wifi oscilloscope disconnect randomly, also during logging.
  Workaround: disable bluetooth since when some paired device is nearby the Android system stops all the apps, including HScope.

TODO List

• Advice for low sampling rate respect signal frequency.
• Reference signal cannot enabled when HS101 connected by Bluetooth.
• Add legend to cylinders timing overlay.
• Enable CH-0 move on Automotive Module
