pyserial on android device

[harryberlin]

Hello

i tried to use a usb serial silabs on my android tablet on kodi (xbmc). the serial device got the path "/dev/bus/usb/001/002"
for pySerial i needed to download the modul importlib and placed in serial folder.
but pyserial can't open the device.
there are some other access rights required?

to be sure the device is working. i did a small test with the app UDevTerm. result was ok.

Android does not come with drivers for USB devices (except some support for HID and mass storage profiles). So there is no serial device provided by the Kernel and pySerial won't work here.

You may be able to write an URL handler that works with the low-level USB API that android provides, but that may also depend on the Python binding you are using, if it exposes that Android API. In any case you need to know how to talk to the USB firmware. There are also USB-Serial libraries for Android, that do this low-level stuff. The App you have used to test most likely uses one of those.
