CC1310: 串口接收数据异常

Part Number: CC1310

CC1310模块在串口开启的情况下,与模块的RX脚连接的串口数据发送脚先拉低50-100ms,然后再拉高并发送数据。此时1310模块无法接收到数据。

为什么会出现上述情况?

如何解决?

串口配置如下,接收采用UART_MODE_CALLBACK模式。

UART_Params_init(&myuartParams);
myuartParams.writeDataMode = UART_DATA_BINARY;
myuartParams.readDataMode = UART_DATA_BINARY;
myuartParams.readReturnMode = UART_RETURN_FULL;
myuartParams.readEcho = UART_ECHO_OFF;
myuartParams.baudRate = 9600;

myuartParams.readMode = UART_MODE_CALLBACK;
myuartParams.readCallback = hal_uart_Callback;
