Possibilities. OTG adapter or USB cable faulty. OTG plugged in to Pico instead of Phone. Adapters used to convert from Micro USB to Type-C or vice versa - this usually doesn't work with OTG. Phone might require OTG to be enabled in settings (unlikely). You can send a photo of your setup to me if you like.

The app asked for 5 stars. I don't see a reason not to give it 5. If that changes I'll update this review. Open source projects are the future. This is literally making the world better. Great work!

A very nice oscilloscope app. I like the Wifi settings like the AP setup. Now it is possible to operate wireless, away from home, without the internet router.
