Code:

uart_div_modify(0, UART_CLK_FREQ / 115200);

// or in your case
uart_div_modify(0, UART_CLK_FREQ / 19200);

at_setupCmdUartDef(0,"\"=19200,8,1,0,0\"");




btw, which doku you have read about api at_setupCmdUARTDef then parameter stands in this how it must be call.

or perhabs this ..

However, I failed to set baud rate in user_init() by following line
at_setupCmdUartDef(0,"=19200,8,1,0,0");
It just response ERROR
Does any one know how to setup default baud rate in user_init()?
Note: I'm using esp_iot_sdk_v1.1.0_15_05_22
thanks
