Hello fellow programmers,
I’ve got a question regarding the realisation of an app which should be able to send AT commands via USB to a connected hardware.
Is it possible to send these commands over USB without root? I would not want to have rooted phones as target market as I want the application to be useable for the average Android platform. Is there any solution out there which you know and can give some links to that?
cheers

If the phones support the optional usb host api then likely yes. You will probably need a USB-OTG style adapter cable which grounds the extra pin to help put the phone in host mode.
If not, no, unless you have one that can be made a usb host via kernel modifications (requiring root, likely kernel reflashing, and possibly a special cable to inject power)
