UART0 rx data

[wtpaul]

in version 3.3.1 rxdata could be received and processed, allowing for a user test menu to be utilised.
I upgraded to ver 3.3.2 today and data is not being received.
Does anyone know what has changed?
And if there is a simple fix please.


UART0 init

Code: Select all

uart_config_t uart_config = {
	  .baud_rate = 115200,
	  .data_bits = UART_DATA_8_BITS,
	  .parity = UART_PARITY_DISABLE,
	  .stop_bits = UART_STOP_BITS_1,
	  .flow_ctrl = UART_HW_FLOWCTRL_DISABLE
	};
	uart_param_config(UART_NUM_0, &uart_config);

	uart_set_pin(UART_NUM_0, TXD_PIN, RXD_PIN, UART_PIN_NO_CHANGE, UART_PIN_NO_CHANGE);
	uart_driver_install(UART_NUM_0, RX_BUF_SIZE * 2, 0, 0, NULL, 0);

//	setvbuf(stdout, NULL, _IONBF, 0);
	setbuf(stdout, NULL);

	ESP_LOGI(TAG, "UART0 initialise\r\n");

to access input data

Code: Select all

rx_cnt = uart_read_bytes(UART_NUM_0, buf, length, ticks_to_wait);	

to print to the uart (output mixed with log data)

Code: Select all

int menu_printf(const char *fmt, ...)
{
	int		str_len;
	va_list 	args;
	va_start(args, fmt);
		
	str_len = vprintf (fmt, args);	//to uart0
	va_end (args);
		
	return(str_len);
}
