AT 1.7.0 - AT+UART_DEF? always return 0 for every parameter #213

I've programmed AT firmware 1.7.0 to ESP-WROM-02 and AT+UART_DEF? always return 0 for every parameter. I tried it a few days ago, then setting baudrate to other was failed too. But today I was able to set baudrate to 921600 with AT+UARTDEF= command. It's interesting. After baudrate was set successfully, AT+UART_DEF? return correct values.

Hi， If you haven't sent AT+UART_DEF=xx command, the value in the flash is empty, so it returns 0. If you want to query the current baudrate, you can send AT+UART_CUR?
