无法使用SIM800L在Thingspeak上发送连续数据

标签： tcp microcontroller pic

我正在尝试通过与SIM800L和PIC16F1936的TCP / IP连接在Thingspeak上发送数据。但是它并没有向峰值数据发送数据，同时ADC值随着模拟输入的变化而变化。我找不到我想要的东西。

它在while循环中卡在“ SENDING DATA”上，但Analog val工作正常。

我对该程序做了一些更改。现在它正在发送数据，但是只有一次。 我正在尝试发送连续数据，但到目前为止我还没有运气。 下面是代码。

}

发送数据后，它卡在了while循环中的SENDING DATA上，但ADC值仍然更改。
