I was wondering can Spark Core can be controlled over Android USB (OTG) instead of WiFi?
@mrabie, can you provide more information of how exactly you want it to be controlled with OTG?
It’s not clear but the STM32F103 probably does not come with OTG Host capabilities.
Sorry for the late reply. I have a project that I want to control the core from an Android tablet directly from the USB port. Can I use the Spark Core like IOIO?
I’m afraid the core might not be able to handle that as a USB host mode so something like a usb host shield might be considered to achieve what you want to do.
I would personally use Bluetooth to perform control that way.
