问题 It looks like the UsbManager is gone in the build. How do we communicate with usb peripherals now? Things like usb->serial etc using https://github.com/mik3y/usb-serial-for-android 回答1: Currently the Peripheral HAL doesn't recognize usbserial based UART peripherals. But if your usbserial device (ex: Arduino) exposes individual UART TX RX pins, you can communicate with it using the UART Peripheral API. Caveat: Don't forget to cross TX and RX when connecting the peripheral to the UART board of

问题 I'm trying to write to a value on AT.
