Hi arpruss!

I'm Alberto, from Argentina.

I'm trying to use the oscilloscope with VectorDisplay, but I can't use Vector Display in my Tablet.

I can use VectorDisplay' circles example if I try with my cell phone but I can't with my tablet.

The tablet has USB OTG and it works ok.

When I install VectorDisplay in the tablet and I open it (without my STM32 connected), it queries me for the permission, which sounds strange.

When I connect the STM32, VectorDisplay app doesn't communicate with it.

I installed an app from the PlayStore which lists the USB devices connected to the tablet, and it says there's two devices connected. One is the STM32 and the other is the Wireless Controller of the Tablet.

When I disconnect the STM32, that app lists only the Wireless Controller.

I suspect that the VectorDisplay is always trying to communicate with the first USB device encountered (the Wireless Controller) and it never try to connect with the STM32.

It doesn't matter the order I connect the STM32 and VectorDisplay, it never works.

What do you think?

In my cellphone the USB devices app only shows the STM32 when it is connected, and the VectorDisplay works fine.

I wait for your response,

Best Regards,

Alberto
