    UART in Host Controller Mode

    abelardo.gonzalez_1573446

      I am using the Host Controller Mode in the PSoC 4200 BLE CY8C4248LQI-BL483. I want to use the highest speed available 921600 bps 

         

      I get this message:

         

      Clock Warning: (BLE_HAL_Uart_SCBCLK's accuracy range '12 MHz +/- 2%, (11.76 MHz - 12.24 MHz)' is not within the specified tolerance range '14.746 MHz +/- 5%, (14.008 MHz - 15.483 MHz)'.).

         

      It seems that the UART needs a clock 16 times the baud rate. If I assume that the clock in use is 12 MHZ Cristal freq) I could operate the UART at 750000 bps.

         

      I have done that; I send a command HCI_RESET and the device response with a envent that has the expected number of bytes (7) but they are all 0xFF
