WebUSB on Android Smartphone

[TedNIVAN]

Hi there,

I have an app (link here) using webusb that works well on PC. I'm able to detect an Arduino board and connect to it.
However when I try to use the same app on an Android phone (Android version 10), I can detect the device but nothing happens when I click the connect button.

1. Do you guys know how to make a webusb app work on Android?
2. Maybe there are some permissions/settings to enable on the phone?

Kind regards,

Which board are you using? There's a known issue (sorry, I can't find the link right now) where SAMD boards don't respond to descriptor requests properly and that breaks connections on Android.

I'm using the Arduino NANO 33 IoT board which is indeed a SAMD board.

Any workaround?
