1 Fix a Problem

Cannot detect the Oscilloscope
  1. Check if your oscilloscope is supported in the list here.
  2. Check if your phone OTG work with the app USB Device info. After connecting the oscilloscope you should see this:In case you cannot see the oscilloscope with this app it won’t work with HScope. Possible reasons (check next questions for resolution):
  • OTG cable is not good (see next question)
  • Original oscilloscope USB cable too long / not suitable (some user got it working by replacing the USB cable)
  • Phone has not enough power for the oscilloscope
  • Phone USB OTG is disabled (hope not)
My OTG cable has issues?

Your OTG cable may have issue if:

  1. Oscilloscope is not detected
  2. Connection is unstable, the oscilloscope connect and disconnect during usage

The suggested OTG cables are as following:

  1. Flexible USB OTG cable (both from micro-usb or from usb type-c)
  2. Short OTG cable from micro-usb to USB-B (used in most oscilloscopes)
  3. Short OTG cables from micro-usb (Host goes to phone) to micro-usb (for HS10X DIY oscilloscopes)

Enable USB OTG on my phone

Read this if you already tested your oscilloscope / OTG cable on another phone so you are sure it is a phone related issue.

So one specific phone do not support USB OTG. Solutions:

  1. Some phone like some Huawei and Realme smartphones need to turn on USB OTG in the Android settings (go to the Settings -> Additional Settings and switch on the OTG connection)
  2. Need to enable OTG on the Android system. This procedure need first to root the phone, then you can edit an xml file as described here.

It has been found that USB OTG can be deactivated on Android phone (until a fresh restart) when this happen:

  1. USB port goes in electrical protection (too much power requested)
  2. USB device has some wrong usb configuration. A software data error can bring USB freezing on older Android versions (found on Android 4.4 and Android 6, not visible on Android 9).
Scrolling is not smooth

Some user experienced problems with scrolling, the scrolling position is stuck or the scrolling is not smooth. This is due to some phone model that have problems with the touch screen while the phone is charging due to instability of power supply.

To check this issue just enable the Developer options in Android, enable the option to show the taps on screen and/or the tap coordinates. Then you will see that when the phone is charging on the screen it detect wrong taps positions.

To avoid this issue on these phones just do not operate the App when the phone is charging.
