Hi,
Could you send me example how i could work with UART over VOXL2. In Voxl2 ,there is no voxl_io library ,that opens UART port and has voxl_uart_write/voxl_uart_read functionality.
Thanks,

@relevinsky For now your best bet will be to get an add on card that has a UART available for the applications processor. Future software releases will provide access to a UART on the DSP (As long as the flight controller isn't running) but that is not available today.
