Functions
otError	otPlatUartEnable (void)
	Enable the UART.

otError	otPlatUartDisable (void)
	Disable the UART.

otError	otPlatUartSend (const uint8_t *aBuf, uint16_t aBufLength)
	Send bytes over the UART.

otError	otPlatUartFlush (void)
	Flush the outgoing transmit buffer and wait for the data to be sent.

void	otPlatUartSendDone (void)
	The UART driver calls this method to notify OpenThread that the requested bytes have been sent.

Detailed Description

This module includes the platform abstraction for UART communication.

Function Documentation

otError otPlatUartDisable ( void )

Disable the UART.

Return values

`OT_ERROR_NONE`	Successfully disabled the UART.
`OT_ERROR_FAILED`	Failed to disable the UART.

otError otPlatUartEnable ( void )

Enable the UART.

Return values

`OT_ERROR_NONE`	Successfully enabled the UART.
`OT_ERROR_FAILED`	Failed to enabled the UART.

otError otPlatUartFlush ( void )

Flush the outgoing transmit buffer and wait for the data to be sent.

This is called when the CLI UART interface has a full buffer but still wishes to send more data.

Return values

`OT_ERROR_NONE`	Flush succeeded, we can proceed to write more data to the buffer.
`OT_ERROR_NOT_IMPLEMENTED`	Driver does not support synchronous flush.
`OT_ERROR_INVALID_STATE`	Driver has no data to flush.

The UART driver calls this method to notify OpenThread that bytes have been received.

Parameters

[in]	`aBuf`	A pointer to the received bytes.
[in]	`aBufLength`	The number of bytes received.

Send bytes over the UART.

Parameters

[in]	`aBuf`	A pointer to the data buffer.
[in]	`aBufLength`	Number of bytes to transmit.

Return values

`OT_ERROR_NONE`	Successfully started transmission.
`OT_ERROR_FAILED`	Failed to start the transmission.
