c - USR-TCP232-T2 : Basic config and port config commands returns 0xBE 0x45 (Error)

Question

这是我第一次使用USR-TCP232-T2模块(TTL-以太网转换器)。我的项目是通过串口(不是LAN口)对模块进行配置和Tx\Rx。当我发送基本参数配置命令或端口参数配置命令时，结果是0xBE 0x45(错误)。

说明:在初始化期间，我发送读取配置命令。模块返回137字节如下:

任何帮助将不胜感激。

我发现问题了。发送命令的代码是:

u8 BasicSettingCom[] = {0x55, 0xBE, &basicParamsStruct, checkSum};
.
.
SendDataToClient((u8*)BasicSettingCom, Length);

因此发送的是 basicParamsStruct 的指针，而不是其内容。

现在发送命令的代码是:

const u8 BasicSettingCmd[] = {0x55, 0xBE};
.
.
SendDataToClient((u8*)BasicSettingCmd, cmdLen);
SendDataToClient((u8*)basicParamsStruct , dataLen);
SendByteToClient(checkSum);

而且效果很好。
