Hello everyone,

I want to ask does STM32f103c8t6 can be used as an accessory device for android? I want to create a project that uses Android Phone to communicate with my STM32. Instead of using Android phone to power up the STM32, I will use a separate supply to power up both the Android Phone and STM32 while making the two devices communicate. If communication is possible, can you give me pointers on how to solve this problem. Thanks :)

Why specifically STM32?
You ought to be able to communicate with any MCU.
I want to use it becuz its cheap and it can support 3 UART, several GPIOs, and Micro USB which is suited for my requirements. Sadly, i didn't realize it sooner that when android is in usb otg mode, the android device will draw power for the stm32.

I want the android device and stm32 to communicate while the android device is charging and stm32 uses separate source. Do you have some solution to my problem?
