Hi TI Team,

I have a requirement to set 1ms delays between bytes to of TX in UART.

I am using the zed_switch_cc26x2lp of SDK simplelink_cc26x2_sdk_2_20_00_36/simplelink_zigbee_sdk_plugin_2_20_00_06.

Here is my uart setting:

UART_init();
UART_Params_init(&uartParams);
uartParams.writeDataMode = UART_DATA_BINARY;
uartParams.readDataMode = UART_DATA_BINARY;
uartParams.readReturnMode = UART_RETURN_FULL;
uartParams.readTimeout = MSEC_TO_TICKS(10000);
uartParams.readEcho = UART_ECHO_OFF;
uartParams.baudRate = 250000;
Uhandle = UART_open(Board_UART0, &uartParams);

It seems that there is no mechanism to do in uartparams configuration.

How to set inter byte delay in the TX of UART?

Thanks and Regards,

Walter

I suppose you can try to send TX byte by byte and add a delay in between.

Hello Walter,

This type of feature is not supported by the UART Driver. You can implement your own API that uses the UART drivers to send multiple bytes with a delay in between.
