send_data
Send data to serial ports through the UART MCP Server, supporting both text and binary transmission modes for device communication.
Instructions

Input Schema
TableJSON Schema
| Name | Required | Description | Default |
|---|---|---|---|
| port | Yes | 串口路径，如 /dev/ttyUSB0 或 COM1 | |
| data | Yes | 要发送的数据（文本为UTF-8，二进制为Base64） | |
| is_binary | No | 是否为二进制模式，True 时 data 为 Base64 编码 |
Implementation Reference
- src/uart_mcp/tools/data_ops.py:13-40 (handler)The main handler function for the 'send_data' tool. It encodes the input data (text as UTF-8 or binary from Base64) and sends it via the serial manager, returning the bytes written.def send_data( port: str, data: str, is_binary: bool = False, ) -> dict[str, Any]: """发送数据到串口 Args: port: 串口路径 data: 要发送的数据（文本模式为 UTF-8 字符串，二进制模式为 Base64 编码） is_binary: 是否为二进制模式 Returns: 发送结果，包含发送的字节数 """ manager = get_serial_manager() # 编码转换 if is_binary: try: raw_data = base64.b64decode(data) except Exception as e: raise InvalidParamError("data", data, f"Base64 解码失败：{e}") else: raw_data = data.encode("utf-8") bytes_written = manager.send_data(port, raw_data) return {"success": True, "bytes_written": bytes_written}
