Question

我正在开展一个大学项目，我必须使用带有GSM模块的Arduino mega（SIM800），通过GPRS在Android应用程序上使用TCP服务器发送传感器数据。

当我执行AT+CIPSEND时，我在HyperTerminal中收到错误（请参阅随附的屏幕截图和编码）。

超级终端：

Answer 1

首先，使用

使SIM800达到全部功能

set :default_env, { 'PASSENGER_INSTANCE_REGISTRY_DIR' => '/home/MYUSER/passenger_temp' }

然后按照以下顺序：

AT+CFUN=1

在此响应确定之后，您可以尝试将数据发送到服务器。请确保您对以上所有内容都做出响应，否则请尝试打印错误代码并检查数据表中的详细错误。您可以在第343页
