How to use at_setupCmdUartDef

[jerry]

Hi,
I can execute AT+UART_DEF=19200,8,1,0,3 in at mode.
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

Hi,
This works for me

Code: Select all

uart_div_modify(0, UART_CLK_FREQ / 115200);

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